Can pro amps possibly sound good? Crown, QSC, etc

I have several QSC amps and have a few Macrotech 2400 amps, I often see people list things regarding technical aspects of amplifiers, and making statements of this has such a better response time etc, and basically state that the QSC amps are lighter than the Macrotech amps and can match them for sound quality! that is rubbish! I have been trying to find replacement amps for the Macrotech's for years, I have tried every QSC, Dynacord, etc and have been very dissapointed by all!! the difference is amazing! the quality of the sound from a Macrotech cannot be matched by any QSC amp! however the compromise is the weight! but the QSC is nowhere near the quality sound of a Macrotech!!

bryston pro amps....very similar to the consumer amps! matter of fact, pretty much the same, haha. and you get a better price via a pro audio dealer then a high end one!

Yes, I am one of those who has gone through the journey of finding satisfying sound quality and currently use commercial amplifiers. I started with ordinary Sony speakers and then moved to Jamo, then Quad ESL,  and then to Tannoy 12 inch, then Tannoy 15 inch, and currently on Function One. I am very keen to try the new direct AES/EBU input Genelec. That is on the speaker side. I also started off with Sony amplifier, then to Marantz, then to Quad, and compared some vintage valve amplifiers and then Chinese valve amps, then Musical Fidelity, Sudden, and tried commercial amplifiers like Crown, Nexo, QSC, Powersoft, MC2, Full Fat Audio, Lab G., etc. I found that commercial amplifiers can be retrofitted with slower fans to reduce fan noise in quieter home setups. Most commercial amplifiers do not heat up much at all during domestic use. Especially class D designs. I particularly like the sound of MC2 amplifiers in mid and high. FFA is fantastic for bass. Powersoft is an allrounder and convenient with onboard sound card, as you can then use digital AES signal further reducing noise. Lab Gruppen sounds very involving and has a great sound too. The overall sound is slightly different in QSC and Crown with a slightly bright feel. I know that there are many others that I have not tried in detail. Similarly, I find the sound cards like Lynx, Apogee, UA, XTA, etc, all give far better results than upgrading the CD player etc. There is a lot of b*** s*** being pedalled around in the consumer audio sector. There is some, but at least 85% less b s in the commercial audio sector. That, to me is the biggest benefit of moving to the commercial audio gear for home entertainment.  I do not find the commercial solution more expensive than a Naim "Hi Fi" set up, for example. My current set up is computer >AES cable to > XTA 446 > MC2 e45 and e25 > F88 speakers + 15"subs. I recently went to a cinema and found the cinema sound system so appalling that I had to come out. I have visited several hi fi shops and found the sound they sell for a lot of money to be a joke. Some of the very biggest names in home audio sound silly compared to a a stereo pair of commercial Beyma speakers driven by a  Lab Gruppen or a MC2. Period!!

QSC amps and other pro power amps can sound great, although I only use 'em for pro audio gigs (don't like amp fans running in quiet listening or recording rooms). Certainly "bang for the buck" applies with this stuff (I use a "little" QSC amp here and there that's only 375 watts or something per side and will blast along at 4 ohms all day), and I'm not going to drag my groovy living room stereo tube amp around in a road case (although I've never hesitated to drag tube guitar amps around for several decades, so there's that). Note I was recently reading an audio magazine and saw a pic from the Magico factory with a QSC power amp sitting there…wonder what they were using it for?…hmmm…If you need a ballsy home theater amp or anything less delicate than audiophile amps, you can run pro amps at a fraction of the cost of precious "high end" gear…you lose some audio geek cred but so what?

Let me debunk most of the responses. I just bought a Crown K1 amplifier. It sounds as good, as ANY Krell, Audio Research, B&K, Adcom, Muse, Luxman, Hafler amps that I have owned. And it has power reserves in spades. I ran this amp fairly hard for almost 2 hours, and not one time did it ever even get warm. With 350 wpc into 8 ohms, and 550 wpc into 4 ohms, this thing never breaks a sweat. I have the K1 partnered with a Denon AVR 3805 as a 2 channel pre-amplifier. The highs are there, the mid range is there, and the bass is incredible. Transparency is very good. Highly recommended.
