A headphone amp and USB digital-to-analog converter for just $99 each

Schiit Audio's very first product, the Asgard headphone amplifier, left me shaken and stirred back in 2010. It sold for $249, looked and sounded amazing, and to top things off, it was made in the U.S. -- not just assembled here. Most of the Asgard's parts are sourced from U.S. companies.

The Asgard is still in company's product line, and it's still $249. But Schiit has grown since then, and now offers a full line of more expensive headphone amps and USB digital-to-analog converters (DACs) -- which is great. But the company's most recent offerings sell for just $99 each! The Magni headphone amp and the Modi DAC are also made in America, and they sound spectacular.

They're both the same ultra-compact size, just 5x3.5x1.25 inches, and they each weigh about a pound. Both feature an all-metal case, and the design looks pretty serious. The Magni amp puts out up to 1.2 watts, so it's considerably more powerful than your average AV receiver's headphone amp. And unlike those built-in headphone amps, the Magni is not a chip-based amp that costs 20 cents. Most headphones don't need all that power -- but some headphones, like my Hifiman HE-400s, really come alive with more potent amps.

Yes, what you plug your headphones into can make or break their sound. Heck, most $1,000 receivers have marginal headphone amps. (They're not a big priority for most buyers.) But the Magni's innards feature fully discrete FET/bipolar, Class AB circuitry. That means the Magni is built like a miniature high-end speaker amplifier. I don't know of another headphone amp built that way for less than $250, and most $250-$500 amps aren't built as well as the Magni. The amp has just one set of RCA analog inputs on its backside, and a 6.3mm headphone jack on the front panel.

The Magni amp uses an external wall wart power supply; the Modi DAC is powered via the USB 2.0 asynchronous input connection. The USB is the only digital input -- there's no coaxial or Toslink optical inputs, but there's a pair of RCA analog outputs on the rear panel. The DAC handles up to 96kHz/24-bit digital audio. The Modi features switched-capacitor filtering and an active filter section, so you can run long analog cables from the Modi back to your hi-fi system without any loss of quality.

I played the Magni and Modi together, and loved the sound. Like the bigger Schiit amps I've tested, the sound is rich, with lots of detail and oomph. I started with my old Sennheiser HD 580 and Grado RS-1 headphones, and moved onto the brand-new Yamaha PRO 500, Sony MDR-1R, Noontec Zoro, and Koss Porta Pro over-the-ear and on-ear headphones, plus a few in-ear models, including Ultimate Ears UE 900s. I have quite a few more expensive desktop amps on hand, including the other Schiits at my disposal. But there was nothing about the sound of the Magni/Modi combo that I found wanting. They deliver bona-fide high-end sound quality. A lot of desktop headphone amps aren't quiet enough to use with in-ear headphones, but the Magni is.

Then I compared the Modi with the $449 Schiit Bifrost DAC, and it was easy to hear the difference. The Modi is sweet and mellow and very tolerant of cruddy-sounding low bit-rate files and streaming audio sources. But when I played great-sounding CDs, the Bifrost was a lot more transparent and detailed. There's less standing between my ears and the music. But as I did the Modi vs. Bifrost shootout, my respect for the Magni amp's sound went up. The $99 amp easily resolved the differences between the two DACs over my Hifiman HE 400 headphones. Stepping up from the Magni to the Asgard produced similar improvement, but to a much smaller degree. The Magni would still be an outstanding value for double the price.

The Magni and Modi come with two-year warranties. That's twice the coverage of most desktop components in their price range. Schiit has a 15-day return policy, so you can still send it back for a refund if you're not happy with the sound, but there is a 15 percent restocking fee.

Pictures: Civil War Shipwreck Revealed by Sonar

Photograph by Jesse Cancelmo

A fishing net, likely only decades old, drapes over machinery that once connected the Hatteras' pistons to its paddle wheels, said Delgado.

From archived documents, the NOAA archaeologist learned that Blake, the ship's commander, surrendered as his ship was sinking. "It was listing to port, [or the left]," Delgado said. The Alabama took the wounded and the rest of the crew and put them in irons.

The officers were allowed to keep their swords and wander the deck as long as they promised not to lead an uprising against the Alabama's crew, he added.

From there, the Alabama dropped off their captives in Jamaica, leaving them to make their own way back to the U.S.

Delgado wants to dig even further into the crew of the Hatteras. He'd like see if members of the public recognize any of the names on his list of crew members and can give him background on the men.

"That's why I do archaeology," he said.

Poisoned Lottery Winner's Kin Were Suspicious

Urooj Khan had just brought home his $425,000 lottery check when he unexpectedly died the following day. Now, certain members of Khan's family are speaking publicly about the mystery -- and his nephew told ABC News they knew something was not right.

"He was a healthy guy, you know?" said the nephew, Minhaj Khan. "He worked so hard. He was always going about his business and, the thing is: After he won the lottery and the next day later he passes away -- it's awkward. It raises some eyebrows."

The medical examiner initially ruled Urooj Khan, 46, an immigrant from India who owned dry-cleaning businesses in Chicago, died July 20, 2012, of natural causes. But after a family member demanded more tests, authorities in November found a lethal amount of cyanide in his blood, turning the case into a homicide investigation.

"When we found out there was cyanide in his blood after the extensive toxicology reports, we had to believe that ... somebody had to kill him," Minhaj Khan said. "It had to happen, because where can you get cyanide?"

Authorities could be one step closer to learning what happened to Urooj Khan. A judge Friday approved an order to exhume his body at Rosehill Cemetery in Chicago as early as Thursday to perform further tests.

Lottery Winner Murdered: Widow Questioned By Police Watch Video

Moments after the court hearing, Urooj Khan's sister, Meraj Khan, remembered her brother as the kind of person who would've shared his jackpot with anyone. Speaking at the Cook County Courthouse, she hoped the exhumation would help the investigation.

"It's very hard because I wanted my brother to rest in peace, but then we have to have justice served," she said, according to ABC News station WLS in Chicago. "So if that's what it takes for him to bring justice and peace, then that's what needs to be done."

Khan reportedly did not have a will. With the investigation moving forward, his family is waging a legal fight against his widow, Shabana Ansari, 32, over more than $1 million, including Urooj Khan's lottery winnings, as well as his business and real estate holdings.

Khan's brother filed a petition Wednesday to a judge asking Citibank to release information about Khan's assets to "ultimately ensure" that [Khan's] minor daughter from a prior marriage "receives her proper share."

Ansari may have tried to cash the jackpot check after Khan's death, according to court documents, which also showed Urooj Khan's family is questioning if the couple was ever even legally married.

Ansari, Urooj Khan's second wife, who still works at the couple's dry cleaning business, has insisted they were married legally.

She has told reporters the night before her husband died, she cooked a traditional Indian meal for him and their family, including Khan's daughter and Ansari's father. Not feeling well, Khan retired early, Ansari told the Chicago Sun-Times, falling asleep in a chair, waking up in agony, then collapsing in the middle of the night. She said she called 911.

"It has been an incredibly hard time," she told ABC News earlier this week. "We went from being the happiest the day we got the check. It was the best sleep I've had. And then the next day, everything was gone.

"I am cooperating with the investigation," Ansari told ABC News. "I want the truth to come out."

Ansari has not been named a suspect, but her attorney, Steven Kozicki, said investigators did question her for more than four hours.

Mali hits back at Islamists with French, African backing

BAMAKO: Mali on Friday declared a state of emergency and unleashed an offensive against Islamists who control the north of the country with military backing from France, Nigeria and Senegal.

President Francois Hollande confirmed in Paris that French forces were involved in an attack aimed at repelling Al-Qaeda-linked radicals who have triggered international alarm with a push south towards the capital Bamako.

In the capital, officers said the first objective was to retake Konna, a central town that was captured by Islamist forces earlier this week, and confirmed that initial exchanges had resulted in casualties on both sides.

"As in any war, the Malian army has suffered losses, the enemy also," Colonel Oumar Dao told a press conference.

The colonel also confirmed that Nigerian and Senegalese troops were helping to support Malian forces who are, on their own, considered too weak and poorly organised to meet the challenge represented by the various Islamist groups who seized control of the north last year, taking advantage of the power vacuum created by a coup in Bamako.

Hollande gave no indication of the scale of French involvement in its former colony but said it would last "for as long as is necessary."

Sources said he had decided to authorise the deployment of French troops on Friday morning following an appeal for help from Mali's interim president Dioncounda Traore.

"Mali is facing a terrorist threat coming from the north, which the world knows for its brutality and fanaticism," Hollande said.

He said Mali's "very existence", the country's population and 6,000 French expatriates were under threat.

"France will always be there when it concerns the rights of a population that wants to live in freedom and democracy."

France had earlier advised its nationals in Mali to leave the country.

Defence Minister Jean-Yves Le Drian held talks with US Defense Secretary Leon Panetta and was due to talk to his British and German counterparts later in the day.

The offensive came a day after Mali's government appealed to France and the United Nations for help in pushing back the Islamists.

As well as capturing Konna, the rebel forces had moved about 1,200 fighters to within 20 kilometres (12.5 miles) of Mopti, a strategically important town on the frontier between rebel-held and government-held territories.

Hollande said France's support for Mali's action was legitimate in international law and in line with the wishes of the UN Security Council.

The Security Council has already given its blessing for a 3,000-strong African force to be sent to Mali but it will not be ready to deploy before September at the earliest.

That created pressure on France to act quickly and Hollande acknowledged earlier in the day that the situation had become critical.

"They are trying to deliver a fatal blow to the very existence of this country," he said. "France, like its African partners and the whole of the international community, cannot accept this.

Traore will visit Paris on Wednesday for talks with Hollande.

The Islamists' advance has exacerbated fears of Mali becoming an Afghanistan-style haven for extremists within easy reach of Western Europe.

France has led calls for an international response but had, until Friday, insisted its involvement would be limited to providing logistical support for the force being prepared, slowly, by the West African regional bloc ECOWAS.

That stance changed when the Islamists seized Konna, an advance that opened the door to an assault on the capital, according to French defence minister Le Drian.

"Given the political situation in Bamako, it would not take much for the country to fall into the most total anarchy," Le Drian said.

Le Drian said he had been struck by the level of coordination and military organisation shown by the rebels at Konna.

LAS VEGAS--Every year at CES, the Mobile Apps Showdown pits dozens of downloads against one another to see which mobile app emerges as the best. This year's event was the biggest yet, and based on the excitement we saw at the event, we think it will only continue to grow.

Here's how it works: a panel of judges first narrows the pool of entrants down to 10 finalists. The developers of the finalists are then invited to present their apps to a live audience at the Mobile Apps Showdown here in Las Vegas, and the app that receives the loudest applause is crowned the winner.

This year, the 10 finalists in contention were:

At the end of the 10 presentations, the hosts of the event -- comedians, Jon Hein and Gary Dell'Abate -- did a quick roll call with their applause-o-meter. When all was said and done, it was clear by the deafening cheers and applause that the winner of the coveted award was MyScript Calculator, a groundbreaking tool that lets you perform mathematical operations with freehand writing of expressions on your touch screen.

MyScript Calculator may not sound all that sexy, but the handwriting recognition technology that powers it is unquestionably incredibly impressive. It can recognize radical symbols, trigonometric functions, and of course basic arithmetic operations. It can even solve for variables. For more details on MyScript Calculator, check out CNET's First Take.

Also, this is the first year that a single app won both the in-person App Showdown award and the online People's Choice award -- a noteworthy achievement, indeed.

Space Pictures This Week: Australia Burns, Pulsars Wobble

Image courtesy P. Kalas, U. California, and ESA/NASA

This new Hubble Space Telescope image of a nearby star, Fomalhaut, and its surrounding disc of debris have made astronomers sit up and take notice. That's because the picture, released January 8, reveals that the debris field—made of ice, dust, and rocks—is wider than previously thought, spanning an area 14 to 20 billion miles from the star.

Scientists have also used the image to calculate the path of a planet, Fomalhaut b, as it makes its away around the star. It turns out that the planet's 2,000-year elliptical orbit takes it three times closer to Fomalhaut than previously thought, and that its eccentric path could send it plowing through the rock and ice contained in the debris field.

The resulting collision, if it happens, could occur around the year 2032 and result in a show similar to what happened when the comet Shoemaker-Levy 9 crashed into Jupiter, astronomer Paul Kalas, of the University of California at Berkeley, said in a statement.

James Holmes Told to 'Rot in Hell' By Victim's Dad

The father of a young woman allegedly slain by James Holmes in the Aurora movie theater massacre yelled "Rot in hell, Holmes" during a court hearing today.

The outburst by Steve Hernandez prompted judge William Sylvester to have an off-the-record conference with prosecutors and defense attorneys. Sylvester then reconvened court to address the issue while armed court deputies watched over Hernandez at the front of the gallery.

Hernandez's daughter, Rebecca Wingo, was one of Holmes' 12 murder victims when he opened fire in the crowded movie theater July 20 during the midnight showing of "Dark Knight Rises." Wingo, 32, was the mother of two young girls.

"I am terribly sorry for your loss," Sylvester told Hernandez. "I can only begin to imagine the emotions that this is raising."

He then lectured Hernandez about the decorum order in place to prevent outbursts in the courtroom.

"I meant no disrespect," Hernandez apologized, promising there would be no further trouble and he was let go.

The judge decided on Thursday night that there is enough evidence against Holmes to proceed to trial and scheduled Holmes' arraignment for March 12. Holmes will enter a plea at the arraignment.

In an order posted late Thursday, the judge wrote that "the People have carried their burden of proof and have established that there is probable cause to believe that Defendant committed the crimes charged."

The ruling came after a three-day preliminary hearing this week that revealed new details about how Holmes allegedly planned and carried out the movie theater shooting, including how investigators say he amassed an arsenal of guns and ammunition, how he booby-trapped his apartment to explode, and his bizarre behavior after his arrest.

Holmes is charged with 166 counts, including murder, attempted murder and other charges. His shooting rampage left 12 people dead and 58 wounded by gunfire. An additional 12 people suffered non-gunshot injuries.

Sylvester also ordered that Holmes be held without bail.

Holmes' attorneys have said in court that the former University of Colorado neuroscience student is mentally ill. The district attorney overseeing the case has not yet announced whether Holmes, now 25, can face the death penalty.

Venezuela stages inauguration rally without Chavez

CARACAS: With cancer-stricken President Hugo Chavez hospitalised in Cuba, tens of thousands of flag-waving Venezuelans filled the streets of Caracas on Thursday to inaugurate his new term without him.

Bands played patriotic anthems from street-side stages as citizens clad in the red of Chavez's leftist movement poured out of buses to make their way on foot toward the Miraflores presidential palace.

There, they staged a symbolic swearing-in of the people, in place of Chavez, who is too sick to re-take the oath of office himself.

Shouts of "Chavez, Chavez!" and the anti-opposition "They will not return" could be heard as Chavista militants stoked the crowds with fiery speeches.

On one stage, an evangelical religious service was underway, and street vendors sold Chavez memorabilia on the sidewallk.

"I love the president," said Pedro Brito, a 60-year-old law professor, in a red T-shirt with the slogan "I am Chavez."

"He has done a lot for poor people, the ones who had no place to sleep of food to eat. He has shown us how to love the country."

Gladys Guerrero, 35, said she travelled by bus from the eastern state of Monagas "to repay love with love."

Vice President Nicolas Maduro hosted a meeting of leftist Latin America presidents and other foreign representatives who have come to show support for the Chavez government in a period of deep uncertainty about the future.

As pro-Chavez crowds built outside the presidential palace, the opposition called for counter-demonstrations on January 23, the day Venezuela's modern democratic era began in 1958 with the ouster of its last military dictatorship.

"We want to especially address the people of Venezuela, and summon the entire country to give a massive demonstration of force in the streets," said Miriam Montilla, a deputy speaking on behalf of the parliamentary opposition.

The Supreme Court cleared the ailing Chavez to indefinitely postpone his swearing-in and said his existing administration could remain in office until he is well enough to take the oath.

It was the last legal hurdle to a government plan for resolving the vacuum created by Chavez's illness that met fierce resistance from the opposition, which had argued it was unconstitutional.

Leopoldo Lopez, an opposition leader, said Chavez's failure to turn up to his own ceremony had created "an indefinite situation in which we can be without a president, and without clear signs that the president is governing."

Henrique Capriles, who ran unsuccessfully against Chavez in the October presidential elections, accepted the Supreme Court ruling as "binding" but said it did not end the uncertainties facing the oil-rich country.

But even without an official ceremony Venezuela's government turned the day into a celebration of Chavez, who won re-election in October by an 11-point margin, despite concerns about his failing health.

In televised speeches, on Twitter and in work places, the government has made blanket appeals for Venezuelans to turn out.

The military announced it was reinforcing security in the city and at other strategic points to ensure the day was observed peacefully.

And the government stopped a broadcaster, Globovision, from airing videos about the controversy over Chavez's non-inauguration, saying they risked inciting political "intolerance."

Globovision, known for being critical of the government, denounced the ban as an act of censorship.

It has been a month since Chavez, who is recovering from a fourth round of cancer surgery in Havana, has been seen in public -- his longest stretch of absence in 14 years in power.

The government has said that he is recovering from complications from surgery, most recently a severe pulmonary infection that had resulted in a "respiratory insufficiency."

Information Minister Ernesto Villegas said late Monday that Chavez's medical condition was unchanged.

Supreme Court president Luisa Estella Morales, who read out the decision upholding the inauguration delay, also ruled out convening a medical board to assess the health of the president.

Uruguay's President Jose Mujica was the first foreign leader to arrive here for Thursday's show of support.

Bolivian President Evo Morales, Nicaraguan President Daniel Ortega, Haitian Prime Minister Laurent Lamothe, and Foreign Ministers Hector Timerman of Argentina and Ricardo Patino of Ecuador were in attendance.

Maduro highlighted the expressions of support he had received from other leaders who are not attending, like Brazilian President Dilma Rousseff.

In Ecuador, President Rafael Correa said the Venezuelan leader's absence would be a "blow" for Latin America.

Throughout his illness, first detected in June 2011, Chavez has refused to relinquish the powers of the presidency, even when leaving for Cuba for his latest surgery.

The charter says new elections must be held within 30 days if the president-elect or president dies or is permanently incapacitated either before he takes office or in the first four years of his six-year term.
