Pass Amp w/Vandersteen 3's?

I use A Aleph 3 with 2ci,And they never sounded better,More Important that your Pre Amp Is compatible with the 5. That will make all the difference.

Why not ask Nelson Pass? He'd at least tell you what others have found (and recommend that you try the combo before buying, probably). Contact him on the Web, Passlabs.com, I think.
