Using pro amps in a home isn't anything new as this thread would seem
to indicate. There are many people that do this and many bypass the
fans because they don't abuse their sound system and they don't have
any abnormal loads to drive.
If you look at history the dollar per watt is getting better in both the car audio
and pro audio industry, but the exotic home audio industry won't give up their
strangle hold and they insist on selling at high prices. I wouldn't even bother
buying exotic home amplifiers unless I had some crazy load to drive, maybe
1 ohm or less per channel.
Study amplifier design and you will notice there is no fundamental difference
between an amplification stage used in car, home or pro audio. I know
that pro amps have smaller heatsinks, this allows them to pack their power
in that standard sized chassis and this forces them to use fans to dissipate
You can take any pro amplifier design and use this same design and
sell it as an audiophile amplifiers and charge alot more money. To
make this happen, it's easy. A few modifications.
1. The designer takes the pro amp and guts the signal processing, ie,
removes electronic parts.
2. The designer will use bigger heatsinks in a 'normal' sized chassis.
Viola' , now you have a audiophile home amplifier that is 4 ohm stable
and all you did was remove parts and add more metal. /hehe
Do you want it 2 ohm stable ? Then upgrade the power supply transformer,
spend $50 - $100 on the upgrade. Next, double the output stage transistors
and reweak the predrivers. This will cost under $50.
Cool, now you can charge 5x - 10x more that the original.
