I am now operating a Red Wine Signature 15 amp and Tekton Lore-s speakers. After I finally figured out there was slight short in the line input of the amp, that was tremendously detrimental to the sonics and sound stage (sneaky little twit - only certain recording were affected - no static just subtle loss of power), I am really blown away by the combination. I have never heard better Coltrane and Davis. Also female vocals and harmony (American Beauty, Workings man dead, CSNY, Dixie Chicks, etc are staggering good - ice music taste- huh. While Led Zeplin, Springsteen are good, badl recorded or re-mastered material can be an issue. Beatles, McCartney are wonderful. The whole set up cost me about $2000. Sound for Sound, best music setup I'vs had. Though my Dunlavy IV and CJ Monos wih Wadia were pretty special. Hope this helps those looking for input;
