Check this puppy out at Steve's Music Store in Toronto

I know it's not a conventional HT amplifier, and it isn't pretty, but for 700 bucks you get 760 watts per channel into 4 ohms, and some pretty good circuit protection to boot. Talk about headroom. Style and noisy fans would probably limit this to an audio closet for most.

And if you get two, and bridge them, well how does 2150 WPC RMS into 4 ohms sound???

Your thoughts?

Seems like we'd need to know THD, damping factor, slew rate, and all that engineering gobbledegook to have an informed opinion.

Still, Zimm's experience with pro-audio amps does give me pause.

Frequency Response: 10 Hz - 25 kHz; +0, -1 dB at 1 watt
T.H.D. 2 x 4 ohms: <0.2% @ 675 W per channel from 20 Hz to 20 kHz
Slew Rate: 17V/µs
Damping Factor (8 ohms): > 400:1 @ 20 Hz - 400 Hz

Are those respectable spec's for this price range?

Distortion is a little high, most solid state amps these days are less than 0.1%, many in the 0.025% range. Slew rate is a little slow, even for a single-ended amp, where good ones hang around 25 volts per microsecond.

Unless you really need that much power, smaller amps generally have better ratings. But can a person really hear the difference between 0.2 and 0.02% THD? Does your listening material have many high amplitude square waves that you need a slew rate of 50V/µs for accurate playback?

I didn't list it, but the cross-talk was surprisingly high on this amp: -60 dB. That may actually be audible in some cases.

Most pro amps are in this price range, at about $300/channel. You can probably do better if you look around. Just to give you an idea, Outlaw's excellent 7-channel amp is $2149, but only delivers 300W into 7 x 4Ω.

Peavy, Qsc, Crown, Behringer, a number of the pro amps have been tried by a few around here with great success, as Chris noted the cross talk and THD does seem to be higher on some of the pro amps which may or may not be noticeable. Also have to watch for XLR only inputs for many pro amps as well.

Peavy is a well known name, at least to musicians, and not a fly by night company. I am just curious if they can design and manufacture a power amp this powerful for that price. And I do understand it could use some refining, whether that refinement will be audible or not is an interesting conversation. I can only imagine what the profit margins are on some of the more exotic no-pro home audio power amp companies.

I am not advocating that anyone needs 700 plus wpc in their living room. However, it is a fraction of the cost of some of the more exotic amps and has more than double and even triple the power.

Yes, I think so.

Paul, it wouldn't sound any different than 215 watts(or 21.5 watts)if they weren't actually used.

Enjoy the music, not the equipment.
