Integrated Amp Reviews

I'm a basically a tube guy, but I've never warmed up to most lower-powered integrated tube amps. Although I quite enjoyed the time I spent with the Cayin A-50T, which I reviewedhttp://www.stereophile.com/integratedamps/308cay">reviewed; in the March 2008 issue of Stereophile, over the years I've typically found I'd rather spend time with mid-priced, solid-state integrateds from Creek, Musical Fidelity, or Simaudio than deal with the loss of definition at the frequency extremes that I've heard from many lower-powered tube models. So it was with a bit of trepidation that I approached the VSi60, a 50Wpc integrated amplifier from Audio Research Corporation.

Besides my 20th wedding anniversary and the 15th anniversary of Listener magazine's first issue, this year marks the 25th anniversary of Roksan Audio Ltd., easily one of the most innovative design and manufacturing firms in British audio. Before Roksan came upon the scene in 1985, none of us had ever seen a loudspeaker whose tweeter was isolated from its surroundings by a sprung suspension. Or a commercial phono preamplifier designed to fit inside a turntable, just a centimeter away from the tonearm base. And who among us could have guessed that the Linn">http://www.stereophile.com/turntables/1103linn">Linn LP12's hegemony—among flat-earthers, I mean—would be broken by a turntable from outside of Scotland? Yet the Roksan Darius loudspeaker, Artaxerxes phono stage, and, above all, Xerxes turntable accomplished those things and more, to the genuine surprise of nearly everyone—and to the benefit of our industry at large, as other firms took those ideas and ran with them.

To celebrate his 30 years with the company, Marantz threw designer Ken Ishiwata a birthday party in the form of an assignment: Design a new, limited-edition integrated amplifier and SACD/CD player bearing his initials. (Only 500 of each will be made worldwide.)

We crotchety middle-aged (and older) audiophiles frequently sit around and whine about the apparently rising median age of enthusiasts of two-channel audio. "We need to do something to attract the youts to our cause!" one of us will say. (Youts? See Joe Pesci in My Cousin Vinny.)

As the 2009 Consumer Electronics Show neared its end, I wandered into Blue Light Audio's room, which was dominated by the innards of darTZeel's new NHB-458 monoblocks—think of a 3D "exploded" diagram and you'll be on target. So impressive was that display of brute engineering that I almost didn't notice the amplifier that was actually making the music: the CTH-8550 integrated ($20,300).

If you ever find yourself in an audiophile-type argument and need proof that, in the 21st century, manufacturing high-performance audio gear to sell for a reasonable retail price is becoming an impossibility, point to Vincent T.A.C.'s TubeLine SV-236MK integrated amplifier, designed in Germany and built in China.

After Fred">http://www.stereophile.com/solidpreamps/1207bo">Fred Kaplan reviewed Boulder Amplifiers' 810 line preamplifier and 860 power amplifier for the December 2007 Stereophile, John Atkinson requested that I listen to the 860 in my own system for a while. Never having reviewed any Boulder kit, I was curious.
