I reviewed the Pass Labs XA 30.5 a few months back for <I>Stereophile</I> . I loved it. Now Nelson Pass, known for his impulsive but inspired ideas, has taken the same class-A solid-state power amplifier and transformed it into an integrated amp. Though the new INT-30A ($7150) was only on silent display (the unit seen here didn't even have any guts inside!) I hope to hear it in my own system soon.
Though the <I>Stereophile</I> Product of the Year award is more transparent than an Oscar or Golden Globe, it is no less coveted. In the Ayre room at the Venetian, the proud winners of the <A HREF="http://www.stereophile.com/features/istereophileis_products_of_2009/ind… Amplification Component of the Year</A> award show off their trophy next to a cut-away of their winning KX-R preamplifier. The preamp was featured in Ayre’s system at their suite high atop the Venetian.
Also showing in the Ayre room were their MX-R monoblocks ($9250 each) and also a <I>Stereophile</I> “Product of the Year” in 2007), connected to the actual samples of Vandersteen Model Seven speakers that Michael Fremer will be reviewing for <I>Stereophile</I> in March. The MX-R, like its KX-R brother, is carved out of a single block of aluminum and puts out 300W into 8 ohms and 600W into 4 ohms. The amps were fed by Ayre’s CX-7eMP CD player and KX-R preamplifier and the sound of the MX-R amps driving the Vandersteen Sevens was detailed and— pun fully intended— airy.
Technical Audio Devices (TAD) was showing off new monoblock power amplifiers to attach to their well-known line of speakers. The M600 amplifiers ($26,500 each) feature a graphite cast iron monoque construction to help eliminate vibration. Though imposing in size (they weigh 198 lbs each!) the TAD amps feature only one stage of voltage gain. The M600 also features a 22lb transformer, custom-built 33,000µF capacitors, and can put out 600W into 4 ohms. They accept only balanced inputs and will be available in February 2010.
"How much does this little integrated stereo amp cost?" I asked. $3000 was the reply.
If anyone could possibly bewitch me, it's Ella Fitzgerald. I found it impossible to resist her spell as she sang "Bewitched, Bothered and Bewildered" through the wonderful pairing of Karan Acoustics' KA L Ref MK2 line preamplifier ($17,500) and KA S 180 stereo power amplifier ($9700), Zanden Model 2500 Signature CD player ($20,000), Finite Elemente racks, Cardas Clear cabling, and new Avalon Acoustics TIME dynamic loudspeaker system with new diamond tweeter, ceramic mid, and two 11" Kevlar woofers ($47,000/pair). This system's intimacy, midrange warmth, and complete lack of barriers beckoned me deeper into the magic of Ella's delivery. Wonderful.
At the last few Nordost demos I've witnessed, I've been amazed by the huge soundstage, deep bass, and tonal accuracy produced by Raidho's diminutive C-1.0 loudspeakers. Imagine my surprise when I learned that this little speaker, no larger than many a bookshelf design, lists for $18,000/pair. Then again, it produces a fuller, larger, and more coherent image than many a full-range floorstander of comparable price. It also has a pretty even 6 ohm impedance, and is said to be very tube friendly.
I've been a major fan of Echole Obsession cabling ever since hearing it paired with Kaiser Kawero loudspeakers at RMAF 2008. With those marvelous babies lamentably absent, here it was paired with a loudspeaker new to me, the towering, 500 lb Tidal Sunray ($178,600/pair), whose 6'8" designer, Jörn Janczak, is equally imposing.
Here's a product that should warm the digits of anyone with a vinyl collection. Furutech, who is generally known for its high quality connectors and cabling, will be releasing the $450 GT40 USB DAC with built-in phono stage this March.
