Best integrated tube amplifier, under $3,000.00. No phono needed. Could be used, too.d

My speakers are rated at 86, and is for a small bedroom system, maybe 12x14 feet is size, and has appropriate room treatments. I would imagine anything 25 watts or above would be sufficient.

I would go with something of at least 50 watt/Ch for headroom. I have speakers of the same sensitivity in a similar-sized room and the meters on my SS do occasionally surpass the 100 watt mark, and I don't often listen above 90db peaks. 

Yes, you can typically get away with less power with a tube amp but that's really only due to their soft-clipping characteristics, otherwise, watts are watts and additional headroom will result in a more relaxed, confident sound. 

I had the Cronus Magnum II for a while, it had some audible hum, but otherwise sounded nice with upgraded NOS tubes. I sold it though because I concluded I prefer my 50 watt/Ch Cayin A88T for its greater transparency and dimensionality. Cayin are not very well known but they're essentially the house-brand of the factory that makes Prima Luna. Their amps are built like tanks and have some of the finest point-to-point wiring you're going to find in this price class. Mine was built in 2006 and hasn't needed any servicing other than new power tubes. 

I don't claim to completely understand the relationship between speaker sensitivity and amp output power but there are some observations on that in this review of the Raven Audio Nighthawk III driving Dynaudio Special 40s which are rated at 85dB, similar to your speakers.

I would also recommend contacting John Rutan at audio connection. I recently purchased the newer Rogue Cronus Magnum III from him with KT77 tubes instead of the standard KT120. I prefer the sound of the KT77s which is warmer and has a beautiful midrange. I also installed NOS tubes in the preamp stage. Prior I owned the Primaluna Dialogue Premium with the same tubes but the Rogue has a better overall sound including more detail, larger soundstage and tighter bass.

Rogue is manufactured in Pa. and not in China. They have a small operation and their units are not massed produced. Their support is excellent and they will answer all your questions and concerns. 

The Conrad Johnson CAV45 can be found used under 3k. Worth looking at if you like the sound of EL-34s.

Primal Luna is great as some others mentioned.

I love my McIntosh MA252. Though it’s technically a tube preamp with solid state amp. But you get the warm tube sound out of it. I have it paired with some B&W speakers. I know this setup may be more of a “mainstream” brand setup but it sounds damn good.

I stream via Bluesound Node 2i and it sounds great, doesn’t sound too “digital” at all.
