"....Examples abound: http://matrixhifi.com/contenedor_ppec_eng.htm  It’s no use saying “but I can tell”. All these guys thought that too..."

You guys are like a cult of Dr. Toole. You keep posting this "test" that uses shitty little 6 inch monitors and nobody hears a difference. No surprise there, that system is almost a Best Buy bargain special. You guys have to stop embarrassing yourselves. The REAL test is in your own system with your own source material and we aren't using 6 inch two ways.... 
The Parasound Halo JC5 tamed some of the brightness that I had with the Classe Sigma 2 amp.
Definitely an all around improvement. More musical, better bass control but it did loose some bass punch.

Then I switched XLR interconnects to Mogami's made by Jerry of 10 Audio. This was a big improvement. Detail, clarity and bass improved. I highly recommend them for $109 for 1 meter pair.

To me the amp and the Mogami XLR's ended my search for improvement. My system sounds great to me.

FYI
I was using XLR's by Raven Audio. Jerry cables are listed here on Audiogon.
