Integrated tube amp under $1000 / $2000


Recently a friend asked me which tube amp he could get used for $1000, I replied that maybe for $2000 he could get something decent but honestly I have no idea what to answer. As a matter of fact I told him for a 1000 he might better get SS than tubes. I have Atmasphere MA-1s myself. 
Can anyone provide some constructive advice of decent tube amps with acceptable quality for $1k (or up to $2k) to drive Klipsch speakers, trying to find out the exact model, I think he has Cornwalls.
Thank you in advance.

Rogue Cronus, might be able to go new with the newest version, they have amazing reviews.
I can second the Cayin as I had one paired with the Chorus 2. Much better fit than SS IMO. I was using the A100T. The A50 would be plenty of power for those Klipsch. 
... here's what I am doing as an experiment and an education: for $150,  I purchased a Monoprice PN # 16153: Stereo Hybrid 50w Amp with Bluetooth and Preamp Out. I hooked it up to my Pioneer Elite DV-37 DVD (intuitively I think that the ability of reading a CD is actually better from a DVD player) with my JBL L25 Prima speakers and am learning abit about how different even a cheap piece like this nt amp can sound with different tubes. Why not try it as well and really get into the equipment part  of this hobby...
