David Berning Quadrature Z or Vitus SS-101


I've been using a Vitus SS-101 for some time and it's certainly a fantastic amp. I've been wanting to try a great tube amp that's not sloppy in the bass and i've negotiated the purchase of a David Berning Qaudrature Z. I will a/b test on my system and sell the one that loses the shootout. Any thoughts on what's the better amp?

I took the plunge & bought the Quadrature Zs which arrived yesterday. They sure sound more transparent, airy & vivid than my Plinius. Of course the Maggies need to be repositioned slightly to compensate for the difference in presentation.  Once I get to know the new system better, will probably retain the SA-Ref to drive the Maggie DWM bass panel solely. My wife can't understand why I have so many "boxes" in the hi fi system ^ ^.
@nicknick , congrats on the purchase. I recently went to a friends home for a Saturday of listening and what do you know David Berning came over and brought the Quad Z monos with him. Wow! They sounded good. What sweet power and control. I don’t think they will ever run out of headroom. You made an excellent purchase.
Wow, what an honor to meet the great man himself!!
I knew the Quad Zs were good by reading all the rave reviews, but didn't expect them to be THAT good. They make the pseudo ribbons on my 1.7i sound like real ribbons, & the bass slam is at on par with, if not better than my Plinius SA-Ref. Just wish I had a bigger room to fully appreciate their full potential.
