Studio/Performance Amps for High-End Systems?

As a practicing (hobbyist) keyboard player and audiophile, I am familiar with why one would not use a guitar amplifier for a keyboard, for example. But, I notice that some of the finest brands of high-power power amplifiers for recording studios or live performances (QSC, Crest, Crown and more) cost hundred or thousands of dollars less than high-end "audiophile" power amplifiers of similar or fewer watts/channel. The specs of these musicians' amps, designed to play 20-20K full-range sound through very low impedances (often as low as 1 ohm) seem to equal those of, say, a McCormack, Classe, Krell amp.
Is there something I'm missing here? If one needs 500 wpc or more, why buy a McCormack DNA-500 for $7K when you can get a QSC with 800 wpc into 8 ohms, capable of driving a 1 ohm load, for $2500?

I might hurt people with the following statement, but I'm afraid this is the truth: Proamps are NOT audiophile quality amps with the exception of two brands: FM Acoustics from Switserland and Rey Audio. Sorry.

Good points. Pro amps cover two markets => venue sound reinforcement and recording studios. Only the studios will go for the higher quality sound (similar to audiophile except slanted towards precise/forward sound) whereas the sound reinforcement and music store rental gear tends to be low cost highly reliable high power but lower quality sound.

Elevick/Tsvisser/Davemitchell have all made excellent points. I've worked on High-End and pro gear for years, and have yet to see the pro gear built with the quality of components(passive or active) that are utilized in High-End audio equipment. That's why the stuff sounds electronic, fatiguing, recessive, etc, in the home audio system: It's largely built for brute force and ruggedness. I always recommended Crown for professional installations, but their gear sounds like... well- forget about it for home use! Some of the studio gear being the exception(I'm using a Hafler TransNova 9505 to bi-amp my woofers). Then again- If you can listen to the pro gear and not be bothered by the sound: Enjoy the savings!!

Pro audio power amps are only good for... bass amplification :)

I stand by the statement
Some audiophiles will complain that studio gear sounds like a PA.

Those who categorically dismiss all pro power amplifiers are simply showing their prejudices. The truth is they tend to sound quite different because they are targeted at different types of listener. Huge power is often necessary for realistic unclipped sound reproduction on studio music that has not yet been dynamically compressed/squashed for consumers. Most audiophile speakers would not last five minutes in a studio before the tweeters were blown and the power amp output transistors fried.

Then you have simply not come across EMMLABS and other high-end pro gear with similar quality build to high end audiophile gear.
