Still not a double blind test, though. How long did it take you to switch between the two?

Additionally, I wouldn't count an RCA receiver as my choice in the test. Might fit Catbrat's, though.

Rats. I was hoping my first long form post would be number 17000.

Some say yes, others say no. That's my question.

edit: Cohesion, you seem to be saying the same thing as JohnK, correct? Within spec, amplifiers/receivers sound the same at the same volume levels?


Mostly yes. That is assuming we are comparing amps of decent or better quality and that have not been 'voiced' for other than a flat and neutral sound. However I'm honestly not sure that the amps in ANY receiver would make the grade. On the other hand I think it would be difficult to differentiate, for example, between AdrianD's Emotivas and my ADA1500, except for the power advantage of the latter.

We may have an opportunity to test this theory and will certainly share our results here if so.

Happy listening!

About 1-1:30 minutes.

Why? What's wrong with an RCA receiver? Either all amps are the same or not.
I always said that the closer the amps are, the harder it is to hear differences... if any. Some amps sound different than other while they may sound the same compare to different amps.

All I'm trying to say is that you cannot simply make a blanket statement that all amps sound exactly the same. If it were true, we'll no doubt have "commodity" amps by now.

I only wish someone from Axiom will offer a more expert opinion on this matter.

Adrian, if that's all you're trying to say, there's nothing to discuss: nobody has made such a statement.

You're in luck. There was an excellent response from Andrew Welker on this very topic.

That's why companies have marketing departments, to convince you of things that just aren't so. SUVs and safety in slippery conditions are a prime example of this.

FWIW we do have commodity amps. They're called pro amps and the most recent generation of class D amps deliver a lot of bang for the buck.
