Tube amps under $7500

by distributor, if you mean deja vu, pretty sure their website is not up to date.  my understanding is that the Prime series - which includes the Ovation and my Ensemble integrated - has been discontinued.  But @audiotroy will know better of course.  in the meantime, i’d recommend you look at the synthesis site (synthesis.co.it).

With a lot of tube gear, the difference between an integrated amp and a power amp is surprisingly minimal--if you take the power amp and add input jacks, a source selector and a volume pot, you have an integrated amp.(you probably don't need additional gain of a preamp or the buffering of the preamp).  One is often better off going with a manufacturer's integrated model because it is cheaper, will sound at least as good and will not require a pair of interconnects.

Late to the party..... but here's another recommendation for the Aric Audio Transcend. I've owned mine for a little over six years now with nary a problem. The bass is excellent,which is really important to me with the types of music I love. It actually can be used without a preamp if one wanted to (gain control). I don't because I like being able to adjust the balance via the pre's remote.If Aric ever decided to close up shop any place that services guitar amps could take care of any repairs easily. The way it's laid out internally is neat and accessible. My two cents:-)

@mdalton Right, I was looking at Deja Vu. Really know nothing about the brand. Maybe @audiotroy will weigh in.

@larryi Whether integrated or separate, my question remains how it handles low impedance at low frequencies.;

@jtcf What speakers are you using with the Transcend?

@hickamore 

yeah, vu is not really a distributor, though he’s listed as such by Synthesis.  He’s a dealer - from whom I bought my amp.  One of the reasons Synthesis has been way below the radar screen in the U.S. is that they’ve never had an actual U.S. dealer.  No presence at audio shows, no Stereophile reviews, etc.  The upside is you don’t pay a premium for the brand.
