Heaven In Your Head

April 24: On Saturday, April 22, the audio forum <A HREF="http://www4.head-fi.org/forums/index.php?">Head-Fi</A&gt; staged its first national meet at the Adria Ramada Inn and Conference Center in Bayside, NY. The meet, organized by Aaron Kovics (Head-Fi tag: immtbiker), occupied over 3300 square feet of floor space, most of which was divided into manufacturers' display tables and forum members' demonstration areas. Yep, you read that right&mdash;unlike ordinary hi-fi shows, the Head-Fi meets are opportunities for the attendees to show off their systems, sample and compare professionally manufactured components, and demonstrate their DIY projects. In fact, one of the biggest surprises I experienced when I attended a regional meet at the same venue last <A HREF="http://www.stereophile.com/news/111405headfi/">November</A&gt; was that some of the DIY projects not only sounded as good as the commercially available gear, they were built to standards of fit'n'finish that rival "real" products as well.

Those who say nothing is lost by preferring tubes are in denial.

Ensemble Fonobrio phono preamplifier

The original plan, back in mid-2004, was to audition an entire Ensemble system and then review the individual components over the next two years. Most audio companies produce lines of matching products, but Ensemble takes it a bit further, with a modular approach and extensive commonality of everything from chassis to circuit boards. They firmly believe that <I>everything</I> affects sonic performance, and their approach helps ensure a consistent sound throughout their line.

Grace Design m902 Reference D/A headphone amplifier

In his bimonthly column, "The Fifth Element," John Marks has tried to identify pro-audio components that would be of interest to audiophiles. In his June 2005 episode, John wrote about Grace Design's m902 D/A headphone amplifier ($1695), the Colorado company's replacement for the 901, which had long been a favorite of his. Changes include: the handling of single-wire sample rates of up to 192kHz; unbalanced analog outputs, controlled by the front volume control, to allow the unit to be used as a preamplifier; a cross-feed processing circuit licensed from www.meier-audio.de; power-supply revisions; and the provision of a USB digital input, in addition to S/PDIF, AES/EBU, and TosLink.
