Mission impossible: A bona fide audiophile headphone amp for $219

I don't remember who told me about Bottlehead, but I'd like to thank whoever it was that made the introduction. I review and play around with a lot of audio gear, and as much as I love great budget stuff, the best-sounding products are always a lot more expensive. Not this time; the Bottlehead Crack amplifier I'm reporting on today goes for just $219, and it sounds like it's five times that price. Bottlehead has been selling electronic kits for 17 years.

First things first; $219 buys the Crack as a build-it-yourself kit, but Bottlehead's founder Dan Schmalle assures me the kit is super easy to build by anyone who knows which end of a soldering iron gets hot. It should take an evening or two to complete. The Crack is an output transformerless amp, specifically designed for high-impedance (100 ohms or higher) headphones like many Sennheiser, AKG, and Beyerdynamic models (Bottlehead offers other amps tuned for low-impedance Grado, Audio Technica, etc., models).

Most Bottlehead customers buy the kits, but the company sells factory-assembled Crack headphone amps for $369, and considering the Crack's build and sound quality, it's still a major deal. The amp's chassis, real wood base, power transformer, PC boards, and even that nifty little Bottlehead badge are all made in the U.S.A. The Crack is a bit bigger than most desktop amps--it's 7 inches wide and 11.25 inches deep--and it was designed by Paul Birkeland.

I first tried the Crack with my high-impedance Sennheiser HD 580 full-size headphones. I bought these at least 10 years ago, and played 'em with countless receivers and headphone amps, but the Crack took the HD 580's sound to the next level. The sound was pure and clear, but never hard or bright. That's what the best tube amps do, you hear more of what's going on in the music, minus the edge or false hyped "detail" of typical budget-priced headphone amps. The Crack delivers bona fide high-end sound.… Read more

The 404 772: Where we eat shows like this for breakfast (podcast)

March 8, 2011, marks two important holidays: one is a global day to recognize the economic, political, and social achievements of women past, present, and future, and the other is a fabricated day of rejoicing for the most important meal of the day: breakfast!

This year is the 100th anniversary of International Women's Day, so check out Mashable's list of what you can do to show your appreciation for females around the world. Our favorite is a joint collaboration between Vivanista, CARE, and Sprinkles Cupcakes that helps you organize a Cupcake Party for a Purpose to meet with like-minded women in your area.

National Breakfast Day sounds like a pseudo-holiday fabricated by Kellogg to sell more breakfast cereal, but the company's latest campaign at shareyourbreakfast.com is so cool we don't even care.

For every picture that gets uploaded to the Web site, Kellogg will donate a breakfast to a hungry child with the help of Action for Healthy Kids, a nonprofit volunteer organization that helps out underserved children in America. More than 800 photos of breakfasts have already been uploaded, and you can even text a photo or description of yours with the word "Share" to 21534 or post a picture on Twitter with the accompanying hashtag #shareurbreakfast.

Wilson's all about the advancement of women and eating breakfast, but as usual he's distracted with this Friday's iPad 2 release. On the other hand, he's not as obsessed as this Texan already camped out in line to buy one. It's Justin Wagoner, the same dude who… Read more

Israel eyes Street View amid security, privacy fears

Israel is considering allowing Google's photo-snapping Street View service into the country, but the government is worried about the privacy and security implications.

A team headed by Israeli Minister Dan Meridor on Monday met to discuss the pros and cons of Street View photographing neighborhoods across Israel, according to a press release. The controversial service is due to launch in Israel soon, the release said.

The government sees benefits in Street View's ability to boost tourism and enhance the country's image. But there are clear concerns as well.

In addition to the usual worries that Street View … Read more

Buzz Out Loud 1391: Google's Eric Schmidt is out and CNET New York is in

It's not your regular Buzz Outloud today. From New York City, Wilson G. Tang, Jeff Bakalar, Dan Ackerman and Rex Brian (AKA Scott Stein) take over, and needless to say it's a very different BOL. In this topsy-turvy world, Google's Dr. Eric Schmidt is forced out as CEO. HP joins the fray by rearranging its board of directors with four new members, including former California gubernatorial candidate Meg Whitman. Verizon files suit against the FCC for rules they proposed, and no, the iPad 2 won't be getting the Retina Display--much to our dismay.

DanKam smartphone app aids the color-blind

When Jeff Sparkman draws his comic book-style superheroes with colored pencils he often has to ask other people to tell him what color his masked men turned out to be because he's color-blind.

Now, a new smartphone app can help him figure out what colors he's using and how the picture looks to most everyone else.

The DanKam app, available for iPhone and Android for $2.99, is an augmented reality application that turns the vague hues that 1 percent of the population with color-blindness sees into the "true" colors as everyone else sees them.

The 404 725: Where everybody calls in sick (podcast)

With Jeff too sick to come in this morning, Dan Ackerman and Scott Stein from CNET's Digital City Podcast jump into the studio with me to record today's show.

And don't worry, this will NOT be a repeat of the infamous "Cheese Stands Alone" episode, so big thanks to Dan and Scott for coming to my rescue!

We spoke briefly about Google Chrome OS on yesterday's show, but I'd be a dummy not to ask two of our laptop editors about it while I have a chance.

At Tuesday's Chrome OS launch event, Google unveiled the Cr-48 Chrome Netbook that has a 12.1-inch display, a full-size keyboard, embedded 3G access and 802.11n Wi-Fi, an SSD, and a battery rated to eight hours of continuous use, and more than eight days of standby time.

The laptop won't be available to purchase until the final one rolls out at the end of next year, but Google's Chrome pilot program gives anyone the chance to be a beta tester for the hardware and software.

To apply, start by filling out this form, but hurry because quantities are limited and some lucky geeks already received theirs today!

Speaking of laptops, Dan brings in the Dell Inspiron Duo for show and tell. The creative design marries the traditional folding clamshell laptop computer with a hinge in the middle of the lid that flips the screen 180 degrees, transforming the device into a tablet PC.

You can also purchase an optional speaker dock for higher-quality media playback, and we like that there's a built-in Web cam for video chats, but it's built into part of the screen bezel so it disappears when the display is flipped into tablet mode- doh!

A good portion of the show is also dedicated to a prototype of a new prosthetic arm shaped like a tentacle, but you'll have to tune in to get the full story.

Thanks again to Scott and Dan for coming in this morning, and send your best wishes to Jeff for a quick recovery! Seriously, the show can't go on without at least 2/3 hosts!

Facebook-MySpace joint announcement set for today

Facebook and MySpace have something up their sleeves for later today.

The two social networks sent out an e-mail overnight to news organizations including CNET, teasing an invitation-only announcement scheduled for noon PT today. The invite says only that Mike Jones, CEO of MySpace, and Dan Rose, VP of partnerships and platform marketing for Facebook, will be making the joint announcement.

The terse wording has prompted speculation over what the two companies might announce. The London Telegraph, for instance, cited rumors that MySpace will launch a Facebook Connect button across its site, letting people use their Facebook accounts to access … Read more

Where does Google TV go from here?

Those beautiful Sony television sets featuring Google TV are starting to look a lot like high-priced door stops.

Google TV enables users to view Web sites and Internet video on their home TVs. However, consumers are prevented from accessing content from the four major broadcast networks on the software platform as Fox announced Wednesday it would join ABC, CBS, and NBC in blocking access to their content.

While some Google TV enthusiasts are cautioning people not to panic, noting that Google TV still offers such fare as "The Jersey Shore" and other popular shows from the likes of … Read more

Google News spammer has new site, same trick

It didn't take very long for 70 Holdings--and a similar site tied to a Los Angeles-based search-engine optimization company--to start spamming Google News again.

Last week, after CNET pointed out that a company called 70 Holdings Inc. was spamming Google News under the moniker of Red Label News, Google pulled that content from its site. However, over the weekend 70 Holdings popped back up using one of the 44 domains it owns to once again flood Google News with the same type of nearly empty stories tied to search-friendly keywords and advertising.

Big North Sea wind farm to power up Munich

Swedish energy company Vattenfall announced today that it's partnering with Germany's largest utility to build a massive offshore wind farm in the North Sea at a cost of about 1 billion euros ($1.4 billion) .

The DanTysk wind farm will consist of giant wind turbines supplied by Siemens and spaced out over a 70-square-kilometer area about 70 kilometers (42 miles) west of the German island of Sylt. Construction is scheduled to begin in 2012 and to wrap up by the start of 2014.

Once complete, the 288-megawatt wind farm is expected to produce about 1,320 gigawatt-hours of … Read more
