This is a June 2014 review.

Me: I am an avid audiophile. I know what good speakers driven by a class A vacuum tube amp can produce. That's the gold standard for this review.

I went into it on a budget and with eyes wide open, didn't have $500 or more to spend on an amp, especially an amp that would promise ridiculous wattage and not deliver.

This replaced an expensive name brand home theater amp that was supposed to be a 750 watt unit but really only delivered a tiny fraction of that per channel.

I believe from the other reviews complaining about fan noise and such that I might have got a new and improved model of this amp...

I have a Pyle 40 and another 15 watt per channel stereo amp that cost peanuts and have stood the test of time.

First - my purpose was to drive a couple good speakers from the 70's rated at 160 REAL watts continuous and 500 peak, to comfortable room filling volume - both for musical use and as a public address system on occasion at our business. I wanted clean sound and a lot of it, but for me a clean REAL 100 watts per channel would be plenty.

Next - this pup's a commercial unit - so it has NO RCA connectors. You'll need an adapter cable to hook up to a source. Either phono or XLR to RCA.

Next - there's only really one input and no mixing. So for one source, one set of speakers, you're good. Otherwise you'll need a mixer or some similar device to select inputs.

The results: I got a clean two channel stereo output feeding it with a clean input.

I'm using 8 ohm speakers with success, and I can't relate experience on 4 ohm - but I'd probably not try running 4 ohm speakers with this thing based on my sense of what it is, and the other reviews.

As for power output, 1000 Chinese watts is equal to a claim of 500x2 watts at 4 ohms is equal to 250x2 at 8 ohms, says the ad.

Reality: with speakers rated at 8 ohms, and half rated power, the thing will probably be longer lived.

Sound wise, at full clean output (clipping light on the amp flickers maybe once in 10 seconds) it sounds and feels like a good clean 75-100 watts should with those speakers.  In years gone by I've driven them with 500 watt per channel vacuum tube amplifiers, and the feel is about right for 75-100 watts.

Provided you don't plan to use the 4 ohm speakers, provided you don't plan to hook it up and let it rip full power regardless of the distortion, provided you don't plan to treat it like a crazed teenager - and provided it doesn't commit suicide all by itself - it works fine.

The amp I got is clean sounding, the fans only come on at higher power levels, are they are inaudible against any reasonable musical material except for something with periods of dead silence. Even then, not all that bad. Those listening to the system have said "what fan?"

Out of the box, no hum, no surprises. Do plan to turn it down before turning it on or off.

Upshot: Good as anything I've heard since the early 90's, if your intention is to run real speakers at decent volume with enough headroom to sound right.

If taking your chances for under $100 in the hopes of hitting the jackpot appeals to you, you have come to the right place.

Oh, and it has no UL approval or any other approvals I can see. Caveat emptor!
