Berning ZH270 vs 845 SET amp

I've never had an 845-based SET, but I have had a Wavac 1610, apparently not their most popular amp ever, but it fits the bill for a 'high-powered SET'. I am well aware, though that 845's sound different than 300b's, etc., so not sure how valid the generalization from my experience to other SET's is. Anyhow, I kept my Berning and sold the Wavac. I just could not tolerate the bass from the Wavac, it was too loose, bloated, boomy. Also the highs seemed to be way too rolled off, maybe not the right word but close.

My experience has been that it isn't the Bernings that make poorly recorded Cd's sound unlistenable. I say that because I've had Bernings through many iterations of IC's, speaker cables, preamps, and speakers. I also have many poorly recorded CD's, since I play guitar and listen to a lot of rock music. The only constant in my system has been the 270's. If it was the Bernings, then the CD's should be consistently unlistenable, and they aren't. Currently, many CD's that I used to just skip because they were unlistenable don't sound too bad; not audiophile quality, but not so bad that I run from the room with my ears covered like I used to.
