Greetings & Happy New Year to all.I received my Yaqin tube buffer along with a JJ Tesla 6922 from Pacific Valve & ECE.Co.today & have spent the last 7 hours in an absolute musical orgy!Set it up in my modest home theater system consisting of a Sherwood Newcastle R-771 surround receiver,Marantz DV-7001 & Aura Sound Baby Grand sub/sat speaker system,cabled it with Audioquest Diamondback I/C's & let her rip!The biggest dividends received:1-REAL soundstaging with an honest viewpoint of the recording venue as well as actual seperation of instruments & musicians.2-Vocals have lost thier steely edge & gained richness & weight.3-Amazing ability to hear subtle sounds NEVER heard before in recordings I have listened to a hundred times.BEST DAMN $200.00 I EVER SPENT ON MY SYSTEM!
