UNfortunantly, I didnt find this site or the YOU tube channel untill it was too late!!\nI was bitten by the cable \/ wire bug some time ago when putting together my second "Audiophile Spec." system after selling off my 1st one a couple years ago.\n\nI think I may have bought some "snake-oil" slippery cables!! I do believe in higher quality aftermarket cables But only to the degree of better build quality and parts and NOT normally for sound quality.\n\nI got this Synergistic Research AC Master Coupler X-Series Active shielding + Power coupler I'm not kidding the power cable has a small wall wart that plugs into the power cable!! yes I fell for it!... paid $250 for this thing thinking it would "improve" with all the usual audiophile descriptors that every product seems to get. (havent read a bad review of anything yet)\n\ni bought this cable and was sold audioquest directional speaker cables series 5 thinking I finally got a high enough resolving system that I could tell the difference guess what I CANT! the blue led on the power cord says I should hahah\n\nCan anyone tell me about this super power cord? \nI already have Shunyata cryo. outlets and run a seperately grounded line to the circuit breaker on its own.\n\nthank you gurus for any info!
