Full tube amp under $1600

Hello,
I am looking for tube integrated amplifiers for my stereo. My speakers are vandersteen 1c. Source is couple of streamers with Dacmagic Plus. I need at least 50 watts per channel so that I can also use with my other speakers (Energy Veritas 2.3/Focal 826v) . Condition used or new it doesn't matter. Black Ice Audio has few amplifiers. I couldn't find anything else. Please advise.
