Presumably you're looking for a tube amp I've you've posted on tube-o-phile circle.......
New at that price point, perhaps something from Jolida (integrated or just tube amp). But if you can stretch the budget I think I would prefer Primaluna.
Used, many options. I bought my 1st gen Manley Stingray integrated amp for about $1200, and that's about what they are worth. Been very happy - very punchy R&R tube amp, looks cool, great build. Excellent re-saleability as well if you don't like.
If you want to go in the opposite direction, you can often pick up early used Conrad Johnson tube amps for $1200 or less. I.e. "MV" models from the early 90's. I thinking of getting an MV75A1 that's been refreshed for about $800. Got plenty of power and very warm liquid sound.
I think much of the Rogue Audio gear would be a good used buy and within your price range w/ a bit of luck.
And of course the many modded ST-70 amps out there, "new" and used are good choices.
