I've decided to try Tubes


I have been going back and forth a while. I was thinking of the Yamaha AS2100 to replace my B&K amp (ZU audio Omen Def speakers). For some reason I now have a tube bug. I first thought about DECWARE and now thinking of Primaluna after reading great reviews. If tubes are not for me, both should be easy to resell. I have an opportunity on a Primaluna Prolouge 5 stereo power amp. It has autobias (which is a must for me) and is easy to roll tubes. It comes with KT88's which seem to have better lower end than el34's (from what I read). 35 watts per ch is more than enough to drive my Omen Defs loud if needed (101 db). 

Thought's on the PrimaLuna and ZU combo (Peachtree NOVA-PRE)? I listen to Classic Jazz, Classical and Classic - Prog Rock mostly.

I paired Zu Unions with Atma-Sphere amp and pre and can say they are a winning combination. A used M-60 or  S-30 would be more than enough power and still be in your price range.

Another recommendation for Quicksilver.  Point to point wiring, no circuit boards, big transformers.
With those speakers you should be looking at SET amps. If you want a little more bass, as your post suggests, go with an 845. Here's a beauty, given top marks by TAS:
