Integrated tube amp under $1000 / $2000

I owned a Cayin A-50T for awhile and was very impressed with the build quality and sonics, this after owning tube amps from Dynaco, Rogue, AES and Cary. The updated model, the Mark II, adds a remote and the ability to use KT88 tubes in addition to the EL-34s used in the original. I bought mine with the stock tubes but re-tubed it with Gold Lion reissue KT77s and signal tubes which improved the already excellent sound. The original model like mine goes for around $800 used and the Mark II sells for $1,600 new.

Thank you this is interesting, yours and others recommendations seems to point the Cayin as a good candidate. 

Used Decware mini torii

How's tube life on this amp? Do you have to replace tubes often? 

Some good 2nd hand deals come up on QS monos, but the sweet EL84 20W Integrated is the real bargain if you don't already own a good tube preamp.  

@decooney 
This looks interesting as well, QS could be another option, thank you 

I would like to second sfar on the Cayin A-50T. It really is a stunning amp for the money. I bought mine new and while the stock tubes were decent, I re-tubed it with inexpensive Tung-Sol EL34s. This amp sounds big but sweet and refined with great imaging. Harry Weisfeld of VPI once said about this amp: "The Cayin A-50T is the best low-price amp I have ever heard, and it rivals some of the best amps in any price range." I would tend to agree.

 I am very happy with a 1965 Sansui 1000A Receiver/Integrated amp at 40wpc RMS. Completely restored by Decibel Audio of Chicago. Sounds amazing with my Sansui SP-2000 speakers. Has 21 tubes in total with 2 very heavy Hashimoto transformers contributing to its weight. They do appear now and then on eBay. Need complete recapping. Early 60s were the peak time of tube technology after which transistors took over. I am sure Klipsch can be driven by them, unless they require amps above 200w. Also worth looking for Sansui AU-111 which is an integrated amp from the same era, though it probably will be more than 2k.
