David Berning Quadrature Z or Vitus SS-101

I have to concur with Tubegroover. I have Quadrature Z's driving Soundlab A-1PX speakers and the amps are dead quiet and never sound congested. I can't comment on the Vitus as I haven't heard it.

I heard the Berning in another system. I thought it became congested during large orchestral passages. It also made too much background noise.

What were the speakers being driven? And what was the preamplifier?

thanks for the feedback everyone. darkmoebius, source is lyra titan I, spiral groove centroid arm, spiral groove table, lyra erodian step up transformer into air tight ate-2 phono/pre

speakers are loiminchay kandinsky w/ TAD compression drivers.

Truly, truly, amazing system! The look/design of Kandinsky's speakers always blow me away. I've heard a system with the Air Tight ATE-2 loved every second of it. Is there any particular reason why you aren't considering Air Tight amplifiers?

BTW, I was actually addressing my question to Rtn1 to get a sense of the system context where he heard the Quad Z sound "congested" and with "too much background noise".

dark, i probably should consider air tight amps.

i guess the appeal to me of the berning is that it's going to have very tight bass compared to most tube amps and in my room, even with ample low frequency acoustical treatments, it borders on "wooly" - which is fine. sounds like live music. but a traditional tube amp can tilt it the wrong way.

the berning, with its ability to control the amount of feedback/dampening, allows to couple the woofer without over or undershooting the woofers. you can really dial it in!
