All Amps Sound the Same....

IMO comparing an amp to a mutlichannel AVR is not anywhere in the same area.

The statements the OP posted to me come from someone not very fimilar with the hobby like we are.

For instance it would be a tough day for an AVR to drive certain speakers and I think one would be asking themselves why does my AVR blow up when I choose to run a 2 ohm load on it?

The box stores like Dumb Buy and alike push AVR's as that is what most people go in looking for. Even HTIBs because someone can't even understand the difference between an AVR and a HTIB.

That and when people are listening to crap thru bose systems what would they know? They think they got the best out there due to name. Heck I even work with a kid who was a Bose store manager and tells me I'm stupid for buying audio like I do.

In the end, to each their own. I wish more people could wake up and hear what good SQ is like but then that would mean they would have to take the time to listen in such a busy world.

I think whomever posted the stuff in the OP was just trying to start a fight or rile up folks.

I haven't done direct A/B comparisions in my listening room. But, my guess is that at least some of the affordable multichannel amps from Yamaha, Marantz, Denon and others are competitive with the audiophile offerings of smaller manufacturers. Particularly with speakers that are easy to drive, which is the current trend in speaker design. After all, do people really believe that a Jaguar outperforms a Honda, or that a Rolex outperforms a Timex?

the statement "all amps sound the same" can only be proven mathematically. while it seems intuitive that the statement is false, a definitive proof is necessary.

relying on sense perception is invalid because the senses are unreliable.

can anyone offer a mathematical proof ?

Some people like a Timex because it accurately and reliably tells the time. Some people like a Timex because it shows they are pragmatic and sensible in how they spend their money. Some people like a Rolex because it has a nice weight and feel on their arm and will look like new 10 years later. Some people like a Rolex because it shows they have discerning tastes and the money to support those tastes. How does that compare to amps? Well, some people like their MP3 player because it can hold thousands of songs and play them forever anywhere and everywhere. Some people like their lower cost amp because it shows that they are pragmatic and want reliability. Some people like very expensive amps because it shows that they have discerning tastes and the money to support those tastes. Some people like their expensive amps because the sound is what they have been searching for since forever. And owning it means giving up something else.
You know what is a real waste? Someone who drives a Porsche just to commute to work. This is a car meant to be driven, driven by a driver with the skill to appreciate it. Comparably, a hifi system purchased by someone who does not really listen and appreciate the music it can make. To say all amps sound the same is simply someone who has not yet listened, or heard the music different amps and systems can make.
