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.

Used Audio Research VSI55's typically sell for around $1500.  A little over your friend's budget, but it would sound sublime with Klipsch.  It was a really nice match with my Heresy's.  I'm using Harbeth P3ESRs with it now.
Thank you for the answers, I will be sending these to my friend, he is an audiophile but he is just finding about it now :), his klipsch are Chorus 2.

I agree on the Quicksilver .....  great amps, great company....   I am running their Mid Monos with a pair of Heresy III and its a great combo.
You can get a used Rogue Cronus Magnum 100wpc Integrated for around $1500.00 or so ( the first edition).
