More great stuff thx all.
@yyzsantabarbara Yes I run my DAC3 through an ARC tube pre and then to a Boulder amp. It really sounds good, both through vandersteens and B&W's.
@cundare2 I do think the DAC3 will end up in my second system. I have run it through my Mac before and liked the results..
@yage I did have an Ayre VX-5 amp for a while with my ARC pre which is also zero feedback with my Vandersteens. It sounded great, I do like the boulder better though.
