I posted a few weeks back about how cleaning (and treating with Caig Pro Gold) only the male end of my CD Player PC caused my high end to go from Romance to Hell. No other changes were made.Now several weeks, and a vacation, later my system has returned to a slightly brighter version of its former self. Sweet, romantic and musical again, though a bit more extended and open, listening is fun once again.
I did remove the Pro Gold, and let the PC sit exposed to the air for a week (inexpensive but pretty good sounding Sounstring, brass plated ends I think). Musicality improved slowly after that to just now being wonderful again after returning from a vacation.
Just another observation of how small changes in my system (especially the source AC) can make or break my musical enjoyment. I'd experienced this before with an "audiophile" wall outlet, and a heavily shielded "digital" power cord on the same CDP.
Follow Ups:
The photos on the Sounstring web site show what appears to be nickel-plated brass metal.Your experiment would confirm the undesireability of nickel-plated metal parts in AC connectors, if that is what these plugs are made from.
the prongs appear to be brass plated, though the plating looked a little "distressed". This is a $40 molded cord that Soundstring makes, but I don't think is shown on their web site if memory serves. The outlet that prevously made my system sound "mechanical" was a nickel plated though, 17 layers as advertized.Maybe I'm too sensitive, but colorful tones and good flow to the music makes alot of difference to my connection with it.
IME, the cheap molded outlets with unplated brass blades work better for my filter tweaks.I'm not doubting your results, just looking for a way to fit them into my experience.
Pro-Gold on naked brass should have worked well. Since you found that it did not, I'm wondering what else might explain your results. What sort of outlet do you have? Is it on a dedicated circuit?
I'm using a cheap outlet that came with the house (1989) and a $50 Monster power bar/surge protector for the CDP. My amp sounds best right out of the wall. No dedicated line, and I do get variability in hash level based on day and late at night. When its sounding good, I do love it, cheap as it may be.I've tried two aftermarket outlets now. Both gave a significantly more robust presentation, but less fluid sounding.
Seems like I've disliked my system for a period each time I treated my IC terminations in the past too. Maybe it just exposes the weaknesses of the rest of my system (hash), but I don't understand the change in fluidity/coherence of the speaker drivers that I perceive.
