I am not sure what you mean my reference level. At -6, I was able to illuminate the clipping indicator on a ATI3005 driving my Salons.
A receiver will run out of power and clip/reduce peak levels before it becomes unlistenable.
It can be difficult to hear the sound that is not produced.

By reference I mean what the majority mean. A properly calibrated receiver so that 0 (relative scale) on the MV on their receiver is playing at reference SPLs. http://www.thx.com/consumer/thx-tech...ference-level/

I agree that different people have different hearing abilities. Just like I can't run like Usain Bolt.

All I know is that I'm a value shopper and have gone thru a $199 Denon receiver to $549 Onkyo 708 to Emotiva XPA-5 to Emotiva XPR-5...each time the differences were clear.

I recently bought an XPA-2 for my 2 surround back channels. Doing an A/B on my Revel F208s, I volunteered my wife who couldn't care less about these things. She was able to clearly, on a double blind test, notice the smoother / better sound on the XPR-5.

I agree, your results will vary, but if I had even more revealing speakers like the Salon2s, the difference I'd have to imagine would be amplified (no pun intended) vs. attenuated.

Your results may vary but since the guys who asked the question can hear the difference, he knows where this road will lead.

Several years back I added a pair of UPA-1s to an Onkyo TX-1008 with the expectation bias that it would either be no change or some improvement. Did not expect a step back in two channel. For movies (did not try multichannel music I don't believe) it was an improvement. Not able to switch at all fast so had to rely on notes but to me it was subtle but still distinguishable.

What method did you use for the level-matching? And what levels were you playing at (how loud)?

For every new thing I learn, I forget two things I used to know.

Look, I'm not going to tell people what they're hearing or not or that they're hearing impaired if they don't agree with my experience.
I also believe that there's potentially more advantage to upping power or changing the type amp than simple SPL.
Sure the differences may be subtle but when you're at the level of systems that most here are, the subtle improvements although subtle may not be "small"
or indistinguishable to the listener.
I could cite many examples of improvements to me that are subtle but not small and sometimes those subtle differences can make all or a big difference in my enjoyment.

 

It ain't ignorance causes so much trouble; it's folks knowing so much that ain't so

I told my wife listen to this song and listen to it again afterwards after I switched amps. I don't get all scientific with audio, I just enjoy the music. I hope you understand what I mean.

We listen at pretty loud levels. Perhaps peak levels around 90-95dB at the listening position.
