Recommend me a tube integrated amplifier

I will throw my hat in the ring and suggest the OP look at the Ars-Sonum Filarmonia SM used unit ($2,950) I have listed for sale right now here on Audiogon. Push-Pull Class A pentode 28W/ch EL34 magic. Not fancy feature wise (no remote, no subwoofer output  but there is no problem with connecting a sub to the speaker terminals via speaker level input). Great build quality and since I am the USA dealer/distributor for these amps I can offer a 90 day warranty on the amp (30 days on tubes) and will even extend a full 30 day trial period with full refund on the amp.

Self bias operation means you just hook it up, turn it on, and it makes (great music).  Sound is not stereotypical warm/mushy tubes and not solid state like sounding Audio Research. Clean, pure, great tone and soundstage.

+1 for Rogue's Cronus Magnum iii, but upgrade to the Dark edition at your price range. I have the Dark edition paired with Maggie 3.7s and a Perlisten D15s sub, and I love the combination.

Thanks again for all the great suggestions.

I found an Audio Note OTO Line SE (Level 2) integrated with preouts that I'm purchasing.

More later once I have had a chance to give it a listen.

Someone mentioned the Octave that’s a very nice amp, I tried it before the Audio Hungary and they are different. AH is more of tube amp. Octave is more neutral.
