Why is pro gear so expensive?

I personally believe there is much to be gained from separates. I personally regard receivers as an absolutely horrible concept, and getting worse.

The problem is that electronic solid state deices have a time/heat curve before destruction. It is in all the specs for every solid state device and has to be for the designer. So there is no argument components operating at a higher temperature will have a shorter life. That is not up for debate. The smaller voltage amplifying stages, and especially microprocessors, are especially vulnerable. So essentially it is really bad design to place heat producing power amps, and the more amps you add makes it worse, alongside and in the same case as the small signal voltage amplification stages and even worse to put them in with digital processing circuits.

In addition there is just not enough room to build all those amps with decent sized output devices. In addition I like my power amps to have the output devices tripled and not singles, so six output devices per channel and not two. This makes for much longer life and relaxed reproduction. I can tell you that decent separate power amps sound much better than receiver amps. When using a really well designed power amp versus a receiver the better power amps just really let good speakers come alive. I also favor a unique amp topology which runs cool and gives class A performance with none of the problems. I have used current dumping power amps exclusively since their introduction over forty years ago now.

Lastly a pre pro and multiple power amps enables much more freedom of speaker design with the possibility of a massive increase in performance and realism. I could not power my speakers from a receiver. The design of this system compels the use of separate voltage and power amplification. This 7.1 system is powered by 14 current dumping power amplifier channels.
well said and I concur. $$ not withstanding the best two channel separates better the best 'receiver' in many ways.

TLS guy said:

Hypothesis:
"I can tell you that decent separate power amps sound much better than receiver amps."

Methodology:
???

What are your scientific methods when drawing that conclusion?
your ears for starters not to mention in most cases (as TLS pointed out) superior internals

also, for the record not all quality separates are expensive

I'd like to see TLS and mikado identify in a blind test which is an avr using its own amps vs having external (within the limits of the least powerful amp). Even separate pre-pro and amp vs avr, again within the limits of the avr without driving needy speakers or other unusual circumstances. Can you get better spec? Sure. Can you get more powerful amps with wider range of impedance loads with an external amp? Sure. Can you really hear the difference in normal use for most people? Meh.

He (mikado) has got $27,000.00 invested in dual mono power amps. He thinks they sound so 'musical'. LOL

son, where did you ever come up with that 27k figure ??

did your mother have any kids that lived ??

How does Rogue qualify? What's typical pricing for a 7ch pre-pro and amp combo from the others?

I know what those Pass amps you’ve got retail for. ;)

My mother had more common sense than you.
