LATEST ADDITIONS

I must admit that I had never heard of Brodmann pianos from Vienna. The only Viennese piano manufacturer I was aware of prior to the 2010 RMAF was B&#246;sendorfer, and Brodmann's Bernd Gruhn (pictured) enlightened me, explaining that back in the day, Herr Brodmann had been Herr B&#246;sendorfer's teacher. I mentioned that it was a coincidence that a second Viennese piano manufacturer was branching out into loudspeaker production&#151;B&#246;sendorfer launched an idiosyncratic line of speakers at a New York <I>Stereophile</I> Show a few years back&#151;only to find out that it wasn't a coincidence at all. The Brodmann speakers are designed by Hans Deutsch, who had licensed his designs to B&#246;sendorfer. When that company withdrew from the speaker business, Deutsch approached Brodmann.

Colorado dealer Listen-Up had three rooms at RMAF. The first one I went into featured Sonus Faber Liuto 3-way speakers ($6000/pair) with PrimaLuna amplification and CD player (the latter the Prologue 8 that Fred kaplan and I reviewed for the magazine a couple years back) and AudioQuest cables and a SolidSteel stand. The Liuto speaker is intended to offer Cremona-like performance for half the price; it combines a 1.25" silk-dome tweeter with a 6" woven composite-cone midrange unit and a 7" magnesium-alloy cone woofer. The nicely finished enclosure follows Sonus Faber's usual technique of laminating cherry sections.

The second Listen-Up room featured PSB Synchrony One speakers ($5000/pair) driven by the NAD M2 Direct Digital amplifier ($5999), both of which were very favorably reviewed by <I>Stereophile</I>. Source was the NAD M5 CD player, wired with AudioQuest cables. Listen-Up has been a B&W dealer pretty much for ever, so I was surprised to see them take on PSB; a staffer told me that B&W's <A HREF="http://www.stereophile.com/news/bw_heads_to_magnoliaville">recent decision</A> to have Best Buy sell its affordable speakers led this specialty retailer to look for an additional high-quality loudspeaker line to carry.

I followed my visit to the <a href="http://blog.stereophile.com/rmaf2010/physical_sound_from_kaiser_gte_aud… Acustica</a> room with a stop in a room occupied by Tidal Audio, dCS, and Argento Audio.

A familiar dem track was playing when I entered the large room from Colorado Springs retailer Audio Limits: "There'll Be Some Changes Made," from Mark Knopfler and Chet Atkins. However, rather than LP or CD, it was being played back from a PC running the J-River player and feeding the well-regarded Weiss DAC202 Firewire D/A converter ($6670). Speakers were the beautifully finished Venture Reference II Signature ($135,000/pair), which combines an AMT (Air-Motion Transformer) tweeter with a 7" graphite-coned midrange unit and four 8" graphite-coned woofer. Amplification was the Swiss FM Acoustics 811 Mk.II amplifier (455Wpc into 8 ohms, $128,800) and the FM Acoustics 245 preamp ($23,200). Power conditioning was by Isotek and Audience; racks were from Harmonic Resolution Systems. The full-range sound was superbly clean and effortless, but I couldn't help thinking that the room was not doing justice to this very expensive system's potential.

I had been impressed by the sound Classic Audio were producing from their T1.3 Reference speakers at last March's Axpona Show in Florida. In Colorado, the Michigan-based company was using the smaller T3.4 speakers, which still use a field-coil–energized 15" woofer and Fostex horn tweeter, but with slightly smaller, Tractrix-flare midrange horn crossing over at 300Hz rather than 250Hz. The speakers were being driven by Atma-Sphere M60 tube monoblocks and an MP-1 preamplifier.

"Good grief, those look like Apogees," I muttered as I went into the Analysis Audio room and saw the Analysis Omega planar-ribbon speakers ($22,000/pair). Driven by Arion HS-500 hybrid monoblocks ($5995/pair), which combine a tube input stage with a class-D output stage, the speakers sounded a bit too warm in the upper bass on Jennifer Warnes version of Leonard Cohen's "Way Down Deep," but this could well have been a room effect. The soundstaging was to die for, in terms of stability and accuracy.
