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.

I had been happy with  Rogue Cronus Magnum II for 6 years after some tube rolling with Amperex 12Au7 and Telefunken 12AX7.

I still keep it just as reserve for Silbatone 300B amp and Line Magnetic 508.

A member and colleague here was supposed to list his DH Inspire 6L6 Triode tube amp and the matching LP27 tube preamp as a set/pair, and he also has a Decware Tori he mentioned planning to list on Agon.  Have not seen it yet, will keep an eye out. 
Luisma 31 , I have been busy at work , I have been reading the comments and reading about the suggestions. I Have learned a lot from every recommendations. I appreciate the help.
Because many Klipsch speakers are so efficient, a single ended class A tube amp can do its thing without the need for much power...I use a Dennis Had SEP (12wpc relative to output tubes) with Heresy IIIs and it sounds magical, as well as real good. After years with a push-pull tube amp it's sort of eye opening to hear what well designed single ended amp can do.
Will Vincent offers great stuff, mostly heavily modified Dynaco ST 70 amps.  But he does offer one model with one input and a volume pot.  Highest quality components.
