From the company that changed the definition of thermostat, Nest appears to be getting into the home audio business. You have to wonder what they'll come up with. Nest founder and CEO, Tony Fadell, also called the “father of the iPod” for his involvement in the early development of that game changing device, most certainly has his eye on the "connected hi-fi" market where Sonos currently sits, atop.

Thanks to John Atkinson for giving me the heads up on this newsworthy item from eRacks:
eRacks introduces the first 150TB storage server, bringing affordable petabyte-class storage to a space-hungry market.

Orange, CA, Dec 22, 2010. eRacks Open Source Systems is at the forefront of computer server vendors utilizing the new 2.5TB and 3TB hot-swappable hard drives manufactured by Western Digital.

After reading Getting Started With Computer Audio Part 3: Music, a very kind reader pointed me to the website and their presentation and related video feature Lost In Translation: An Exploration of Lossy vs. Lossless Audio Formats. Presented by Grammy-award winning engineer Andrew Scheps, this is actually a two-part presentation wherein Part 2 lets people listen to different music delivery formats.

We've given our Greatest Bits list a complete makeover in an effort to make it more organized and ideally more useful. As you'll see, we've added "Classes" to each category of component that we borrowed from Stereophile's approach which works very well, imo (see Stereophile's 2012 Recommended Components ). Our Greatest Bits list is based on listening impressions which by their very nature are subjective and also reliant to a certain extent on system context. So the usefulness of this list is to act as a guide to what we consider to be gear worthy of an audition, to help you narrow down your choices from an increasingly crowded field.

If ever an audio event were in living color, it was the Bay Area Audiophile Society’s (BAAS) February 23 live / DSD event at Blue Coast Studios in Belmont, CA. Jointly hosted by Blue Coast Records founder Cookie Marenco, a long-time proponent of DSD who has engineered or produced five Grammy nominated records, and the dedicated president of BAAS, Bob Walters, the two-session event prefaced comparisons of four DSD-capable DACs at three different price points with intimate, live-to-DSD recording sessions with Flamenco guitarist Jason McGuire.

If you've read my review of the Halide DAC HD, you'll know I liked it. And I liked it a lot. I still wonder if I communicated the degree to which I enjoyed listening to music through the Halide DAC HD clearly enough. Sometimes I think I played it a bit too safe and tempered my enthusiasm for it a bit too much. At $550 (when reviewed) including cables on both ends, USB and RCAs, the DAC HD, which is an asynchronous USB DAC that uses Gordon Rankin's Streamlength™ technology and supports up to 24/96, is another entry in my virtual Recommended Components or Things I Really Really Like List.

Yes, you read that right. HDtracks, the grandfather of hi-res download sites, will be launching their own streaming service, HDmusicStream, which will feature all MQA-encoded music all the time, later this year.

The HDtracks website is sporting a new design and while past visitors will recognize the overall layout, there are a few changes that should make browsing more pleasant. First off, you can now scroll through more releases right on the home page and there's a Wishlist feature to save yourself the trouble of remembering. While there were hyperlinks associated with releases on the old site including Artist, Genre, and Label, these are featured on more pages of the new site and releases now get a single page with the different sample rates available from a drop-down menu where the old site split these into multiple pages. For those shoppers looking for more information like DR Values and detailed provenance information for each release, the wait continues.

It should come as no surprise at this point that Neil Young was at SXSW to talk about Pono. I had the opportunity to spend some time talking to Neil Young about his new venture.

I'm headed to Austin, TX and SXSW next week to interview Neil Young about his pending PONO launch. I mean!! If you have anything you'd like me to ask Neil Young about PONO, just let me know and I'll try to work your questions in. I've already got "What's your favorite beer" covered.

The Loudness Petition Group, which consists of members Eelco Grimm (Grimm Audio and HKU University of the Arts Utrecht), Bob Katz (Digital Domain), Matt Mayfield (Matt Mayfield Music) and Ian Shepherd (Mastering Media), is on a mission to cut the legs and logic out from under the excessive use of dynamic compression in our music. Their proposal and petition aims to get streaming services to apply "loudness normalization" by default (the loudness level as defined the Audio Engineering Society recommendations), thus rendering all streaming music equal in terms of volume level. Check out that video for a nice illustration of the problem.

I finally found the "Real-life listening tests" article on the CR website. They compared CD-quality WAV files, AAC files from iTunes, and "high-res files". No details were given as to what music was used nor the resolution of the high-res files. They did however note the test setup:
