    I used a Peavey class D for a long time with subs. It worked real well. Lots of power and dynamics. Never ran out of steam. Was a bit noisy though with the cooling fans.

    I ordered quieter fans for my QSC when I was running it. Made an unbelievable difference. The lights were the only thing that indicated it was on because it was so quiet.

    We need to be educated?????

    95%???, yea right, sure it is, even then it would be totally lossy sounding, kinda like getting 95% lucky, almost, but you just never quite get there and leaving totally frustrated as the final result.

    Everything matters.................period.

    Pro amps stink for home use if your goal is high fidelity. They just don't cut it, period.

    P.s. That certainly doesn't mean those of you that use them can't enjoy them. But those of you who continue to assert they are every bit as good as a well designed "home" amp are kind of clueless. As well as those of you who think the amp doesn't matter. We all have a different audio path, that 's alright. But you will never convince a race car driver a Hyundai is the same as a Ferrari..............because it's not.

    Define that, give some examples please. "Of an expensive, well-made, well-built amp." Because I can tell you for sure that I can damn sure tell a difference between my old trusty Peavey rack amp (guitar rig) and my vintage Onkyo Integra M504. And that is on any of the 12 pairs of speakers I own. Running the same pre, cd/dvd etc.....just changing out amps.

    Onkyo Integra M504, Bottlehead Foreplay III, Denon SACD, Thiel CS2.3, NHT VT-2, VT-3 and Evolution T6, Infinity RSIIIa, SDA1C and a few dozen other speakers around the house I change in and out.

    Compare a high quality amp from the 60's to one built today, there wont be a comparison. What was considered high quality then, and even the 70's, is highly colored in comparison to even a 10 year old Adcom.

    Cheap pro gear sounds exactly like that to me for 2ch stereo.... I use a pro amp in the studio with a pro mixer and generic CD player along with a laptop, makes recorded music sound flat, dull and so on, I would never use it for any sort of serious musical 2-ch listening enjoyment, the gear is just not meant to be used with hi-fi speakers, the noise floor is certainly an issue, works as intended for playing electronic instruments.

    If I hooked the amp to the Sound Labs the inexpensive electronic parts would smoke and die.

    Seems as if this pro gear issue comes along a couple times each year....generally pretty much the same comments, not much left to say, if someone digs it then go for it, however, you can expect some push back from others should you choose to expound its sound to those who have moved far beyond. We all started somewhere though, oh, and I am pretty sure 100% of the membership relies upon their ears to hear music....

    Looks to me like you are throwing all your cards on the table here and looking to start an argument for sure. If it does turn into "dick-sized" argument, I would be careful because your line of thought is rather small.

    To the thread starter.....For efficient 8 ohm speakers,a pro-amp or any high-powered,high current amp is overkill for 2 ch sound.For inefficient 4 ohm speakers with a Crown or QSC power amp,the results will be spectacular.
    To others......Have a nice day!:smile:

    In all the years I've been in audio, that is the absolute worst advice I've heard.

    another idiot for the bozo list.....

    I mean, really. I don't care what you listen to, I really don't. However, I've heard enough amplifiers that I have no vested interest in to conclude that, to my ears, they sound better/different. I chose not to use certain products because I don't like them. Bully for you if you do, however, who is to say that your opinion is any more enlightened than mine?

    20hz,
    I used a pair of 200w mono blocks Class D to power a pair of 12" subs at one point. Never felt the need for more power.
    I also used them to power a pair of Maggies MG-12QR, Mirage M-3si and a few others. Sounded great on all those speakers.
    But of course, there are good and bad Class D out there just like any other design. Hope this helps.

    I thought it sounded familiar, so I looked in my handy Chemical Rubber Company Handbook of Chemistry and Physics and found the pertinent equation:

    Preamp rotation: Krell KSL (SCompRacer recapped) * Manley Shrimp * PS Audio 5.0
