Sonic Impact T-Amp 2




"[Reviewing the T-Amp] has been the most thrilling and incredible experience I've had with a component in, say, 25 years of HiFi listening. This website has existed since 1995, I've reviewed hundreds of HiFi components, inexpensive and ridiculously overpriced ones. I never - repeat - NEVER came across such a stunning piece of gear in all of these years."

And while that may just be a little bit of quote whoring by the folks of TNT audio and we usually are skeptical about audiophile expert claims, at $69.99 this seems worth a try.

I love the T-amp, not only for what it does, but what it makes others say who can't grasp the concept.

It's just a class-D PWM amp (The T is marketing) which is by definition very accurate and efficient. And for those who are used to their cheap-o hundred-watt stereos don't realize what an efficient amp can do with just a few watts. My $25 T-amp running off a few AA's has no problem powering my huge floorstanding 4-way speakers, and quite loudly too. I also have an "oldie but goodie" 70's pioneer receiver that can also kick butt rated only 25watts. New amps are made to be cheap, so they need lots more power to make up for their inefficiency.

But the hi-fi elitists are always used to making a big deal out of nothing; perhaps they went into the T-amp with an open mind (for once) and realized it is every bit as accurate as a decently high-end amp. Of course that's easier to do at such low power.
