reasonably priced tube amps

I'm thinking of buying a tube amp to augment a solid state system I intend to buy (naim or ayre) along with the Dynaudio confidence c1s or Sonus Faber auditor Ms. I'm thinking of the Rogue Cronus, the Cayin 88 or the Manley Stingray. I listen to a lot of jazz, r&b, classic rock, classic pop vocals, Brazilian and African music. I'd appreciate your thoughts.
You don't say it, but you are looking at integrateds only?
Neither of those speakers is particularly suited to tube amplification.

Do some more research into them. The measurements section of the Stereophile review of the Confidence C1 is a good place to start.
A great budget integrated tube amp that I have been very satisfied with is the JJ828. It got a lot of press a few years ago, but fellout of notoriety. It is imported by Eurotubes. Since he doesn't have a dealer network, he is isting them for sale at "call for a great price", should be well under $2000. For reference, the other amplifiers which I own are Pass Labs Aleph3 and AtmaSphere MA1s with all the options and NOS tubes. The JJ is not humiliated standing in this exalted company.
Worth a look see, the SQ-88 from Quest for Sound a 55 watt integrated. Steve Monte great guy to deal with, check his website.
Check the following ones:

Jolida's usually build great stuff on tubes.
IMO, you need *at least* 100wpc to drive the 86dB speakers. 200wpc would be better.

A 55wc tube integrated isn't going to get the job done.

Frankly, for these speakers, I'd look at something like a used Moscode 401HR. You'd get some tube flavor combined with solid state muscle.
I like the Rogue ,have not heard the others,but they are all great amps,these threads are like a car club if you own a camaro then you criticize mustangs and in truth they are both great cars,same here,get your absolute favorite tune and listen to it yourself with the speakers you intend to buy,you will decide what flavors you like not us,have fun and enjoy,Nick
