Tube Power Amp Reviews

It would appear that there are still people out there who are unaware that this is the age of the transistor. Not only are tubed amplifiers not vanishing from the face of the earth, they are proliferating. Audio's equipment directory for 1977 listed three tubed power amplifiers. The same directory for 1984 lists over 30 of them, and the Quicksilver amplifier is not even included!

We mentioned in the last issue that we were becoming increasingly disturbed by "a certain manic quality that is creeping into this pursuit of sonic perfection." We were referring then to a manufacturer's announcement of the imminent availability of a speaker system weighing over 1000 lb per channel, but we could just as well have been speaking of this behemoth from Audio Research.

It is not at all unusual these days to find manufacturers producing "matched" speakers and amplifiers that are designed specifically for one another. But it is very unusual to find this being done by an amplifier manufacturer who doesn't make loudspeakers. The Futterman H3-A is one of these rarities—an amplifier designed primarily to complement one of the best, and one of the hardest-to-drive loudspeakers on the market: the KLH Model Nine.

These days, listeners the wide world over enjoy hearing their music recreated for them by equipment whose origins are international; trade isolationists might consider the example of PrimaLuna. This Holland-based company's operations span three continents, with designers from Floyd Design and Durob Audio in the Netherlands, manufacturing in China, and input from California-based Harmonia Distribution.

If you go to Tokyo, there's a good chance you'll develop a new appreciation for shopping malls. The Japanese know malls. They know just what to do with them. Inside a Tokyo mall, you can peruse the usual handbags and shoes in their unending variety. But you can also stare at Fuji apples as large as a baby's head swaddled in tissue paper, flip through the world's most exquisite stationery, stock up on fabric from the 1920s, and taste things that will haunt you well into retirement.

"None of the amps I build are better than the others," Justin Weber of Ampsandsound told me not long after we met. "They are just different." I may have smirked inwardly. According to his company's website, Weber makes no fewer than 23 amplifier models, ranging from the $2700 Kenzie OG to the $38,000 Arch Monos. Are they really all equally good?, I wondered.

Nick Doshi is cautiously reserved when he talks about his amplifiers, preferring to let the products speak for themselves. At every show I've heard them at, from Chicago to DC to Munich, they have done exactly that: Every system I've heard featuring a Doshi amp has delivered great sound. When I pressed him as to why, he just smiled.
