Other than upgrading my speaker cables (cardas) and power cords(cardas)..I'm done. The journey was arduous, time consuming..but now I just enjoy the music. Digital system with almost analog/tube sound. Built this with the help of Audiogon for about $6600. OK, maybe add a Magnum Dynalab, but then I'll need a preamp and maybe a turntable, then again maybe NOT.
