I'm loving this amp more everyday because of the way it responds so well to changes made.I swapped ics around to connect the ZenWave DSR from pre to amp,then the Silnote from Dac to pre and BAM!Just like the old saying about the difference between clean and dirty glass.
Then I replaced the Silnote sp cables with an old pair of Audio Art silver plated copper just to see if it liked that combo as well as the Cullen cord it does so well with, and again BAM!This amp along with the Harbeths evidently matches up best (to my ears) with silver plated copper coming and going. I suspect a heavier gage sp cable may be even better,maybe a little richer. Not dissing Silnote at all, I really like their products. They are silver,copper,and also combined with gold, so it seems the addition of the gold is not as pleasing to me.With my tube amp it is a great match though.
What I'm hearing now is palpable images,plenty of micro detail, a realistic soundstage, wonderful timbre, very good but not great bass,and lost some shimmer on top by switching the ics.Just being nitpicky:-)I'm very happy with the system right now. My Zeppelin CDs sound great along with my acoustic CDs and streamed music.
