Do your ears deceive you?

My system is modest but very sensitive to any changes. However, once I had some fun with comparing Wywires Diamond, that's their top of the line $2700 RCA cables, and older Gabriel Gold Infusion RCAs. I was using my trusted Nakamichi 682ZX deck as a source and VAC Avatar integrated amp. Damn, they were so close, but at the third go I did hear slight differences, not better/worse but differences. They both sounded great and I use then both. In higher resolution system the differences might be more pronounced, I don't, know. Wywires is a little more balanced and Gabriel Gold more engaging. I bought them both used, Diamond for $1150 and Gold for $200. For most recordings, especially acoustic music, I actually prefer Gabriel Gold a little.

Yet another comparison. First I put Purist Audio Dominus Rev B power cord on PS Audio regenerator and Purist Aquila on VAC amp and then reversed it. The difference was big, with Dominus on VAC and Aquila on the regenerator it was much better in every respect.

My ears don't deceive me, as far as I know. I asked another non-audiophile person to listen to all these changes as well. Same conclusions.

“Do your ears deceive you?”

Yup

Thats why I rely on my lying eyes….

"If you can’t hear it you either have the wrong cables, an insufficient system, an inability to hear those differences or confirmation bias against cables." 

Or Door #4, there are no audible differences to be heard.

Claiming  'insufficient system"  is the height of arrogance close only to  blaming "an inability to hear those differences."

Maybe you could define of what a sufficient system is made.

"Maybe you could define of what a sufficient system is made."

One where you can hear the differences between cables.
