PRE/AMP Combo or Integrated?

if you would consider tubes, and 45 wpc is enough, try cj's mv55 & pv10a combo (on this site, i've seen the amp trading for between $1000-1200 and the pre-amp for between $500-700). i prefered the sound of these separates to the sound of cj's integrated offering (combining both of these, the cav50). imho, this combo handles most/all music well.

Did you consider a tube intergrated? Some people prefer the sound. New would be the Jolida. Best used for a little more than $1500 would be a Jadis Orchestra. If you want solid state, there is Musical Fidelity and Audio Refiniement(new), or the Krell and Classe(used).

I've had an Audio Refinement Complete (built under license by/for YBA) in my office for the last several days while my amp gets fixed, it's a nice integrated, and it can be had for around $700 on the 'net. I own more "rarefied" gear so I'm kinda fussy, this is one nice piece of equipment, if 50 watts a side is enough for you...

Skip the Krell integrated unless you listen exclusively to rock and popular music. It has a great bottom end, but not great mids and highs for classical. There's a lot of them for sale on Audiogon and other sites. For $1,400 I'd go with a used Classe integrated - preferably the CAP 151 or the CAP 150 (same guts, different faceplates). Both feature a pre-amp shutoff button, which allows you to connect a separate pre-amp if you decide to upgrade later. The Classe units are built like tanks, and are very musical, especially when compared to the competition in your price range. Good luck!
