Tascam DA3000 route with a ZBIT input directly to the TORII MKIV.
Best way to go. Adjusting the gain of the ZBIT with the input gain of your Torii.....very nice.
I've been tempted to get a ZBIT and I would need a KS1130 or 1136...but I don't want to spring for it. I will live with my output tranny's Steve put in....they are pretty damn good.
I use a well searched out cheap Transport that competes with the $$.
(I have two others on the shelf/new/boxed).
Lately, I am enjoying the adjustment of my ZDSD's input volume and output level.....manipulating Redbook CD's for the way better!
Truly, the magic happens with tube rolling and the best cabling...proofs in the pudding... . Of course you need the DA3000 Steve chose & modified to ZDSD or add the ZBIT for the best + ZMA or a Torii MKIV = that's a given/we know.

.....waiting for Kimber Carbon/release.
