Power Amplifier Reviews

<B>On the Kouch</B> <BR> Actually, Dr. Melfi has a chair and a couch. Her expression is noncommittal as I choose between them&mdash;the psychoanalysis has already begun. Right away, she suggests a word game: she'll say something, I'll respond with the first thing that pops into my head. I've used the technique myself to out disloyal employees in the, uh, refuse recycling business. I guess that semester and a half of college was money well spent.

I've been sitting here at my computer for over an hour without typing a word. I'm showing signs of terminal writer's block, but I wish I were that lucky. In truth, I'm just speechless, and the Cinénova Grande amplifier from Earthquake Sound Corporation is the reason why. Several weeks ago, a massive wooden crate stamped "heavy" arrived at our sound lab in Woodland Hills. I had seen crates like this during my stint in the military—they usually contained Patriot missile warheads. We gathered around it like cavemen observing fire, poking at it and wondering what it might be. Finally, I worked up the nerve to open it up.

In a sure sign that the low-cost DAC is finding its place as an object of mass consumer desire, NuForce has released a 24-karat gold plated version of their uDAC-2 converter-and-headphone-amp combo unit

Few audio companies are as closely associated with a single individual as Pass Laboratories is with its founder Nelson Pass, a man who has always blazed his own path when it comes to designing audio gear. Pass founded Threshold Electronics back in the early 1970s, but when he wanted to explore new, simpler circuit topologies in the early 1990s, he created Pass Labs as a way to market his latest creations.

The two integrated amps in the Pass Labs line, the INT-150 and INT-30A, are a good example of his less-than-conventional approach, seeing as both appear to be  identical except for the critical question of output power. Physically the two amps are indistinguishable, with exactly the same functions, weight, dimensions, and even price tag. It's only when you take a peek at the spec sheet that the differences become apparent, with the INT-150 delivering a healthy 150 watts per-channel, while the INT-30A tops out at just one-fifth that amount.

So what gives? Why would anyone buy an inline four when they're offering you the V-12 for the same money?

I am of the school that believes that more power is always better than less power. That school also professes that amplifiers, while operating within their linear abilities (a big “if”), are not generally distinct in their sonics.
