NAD is well known for its traditional, high-quality, and relatively affordable integrated amplifiers. At this year's CES, NAD introduced a revolutionary new integrated, the M2 ($5999). NAD's Stephen DeFuria (right) told me that the M2 is what NAD calls a "Direct Digital" amplifierthere is no analog circuitry!
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.
Also showing in the Ayre room were their MX-R monoblocks ($9250 each) and also a Stereophile “Product of the Year” in 2007), connected to the actual samples of Vandersteen Model Seven speakers that Michael Fremer will be reviewing for Stereophile 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.
Though the Stereophile 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 2009 Amplification Component of the Year 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.
I reviewed the Pass Labs XA 30.5 a few months back for Stereophile . 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.
New to the Pass Labs product line is the XP-25 two-chassis, solid-state phono preamplifier ($10,600). Intended to be designer Nelson Pass’s statement phono stage the XP-25 allows the user to select gain, and resistive and capacitive loading to match any cartridge you might want to use. The XP-25 will accept two line inputs and offers both single-ended and balanced outputs.
Amplification in the Signature system in the Lamm room featured the ML3 Signature power amplifiers ($139,290/pair). Like the LL1 preamplifier, the ML3 isalso a four-chassis system. These 32W, single-ended, pure class-A amp is based on a direct-heated GM-70 triode.
One of the great things about coming to CES is getting the opportunity to hear gear that’s rarely near. I was really happy as I strolled down the 35th floor to walk into the Lamm room. I don’t have a Lamm dealer in Minneapolis so I haven’t ever had the chance to hear this lauded and expensive tube gear.
This is Rosemarie Torcivia. I just met her today. She works for Source Interlink Media, the parent company of Stereophile and Home Theater magazines. She gets to spend her days at CES in the Stereophile and Home Theater suite answering questions and being a knowledgeable and friendly face for the dealers, manufactures and readers who pop in to say hello. She was thrilled when I took her picture and told her she was going to be in the official Stereophile CES blog. I was thrilled when Rosemarie helped Jon Iverson and I get lunch today. I like Rosemarie and I bet you would too.
Minneapolis-based Bel Canto Design (props to my homies) brought a new amplifier to CES this year. The e.One REF150s ($1495, shown on the lower rack) is a fully balanced dual-mono amplifier that will put out 150Wpc into 8 ohms This may be a wee-sized amplifier, but it sounded huge strapped to a pair of new Joseph Audio bookshelf speakers.
