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

I would look at brands Line Magnetic, Primaluna, Rogue and the brand/model Elekit 300b.  But as others state above your room size and power requirements play a significant role in matching too.  

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.

A lot of good suggestions here..there is a nice used Ayon Spirit III gen IV for sale on Audiogon right now that would probably give you enough power in either pentode or triode mode depending on your preference

Just bought the Octave V40 mentioned a few posts up (it was in the mail at that time). Replaced the power tubes with Gold Lion reissues. Figured I’d share my message to the seller:

”KT88s arrived a day early and have been in since lunch. WOW! Fantastic. All bias adjusters work fine. Really good sound. I’ve been working backwards from the source/streamer/DAC side of things and just pulled the trigger on the Dynaudio Special 40s. This amp is the last step. Think I’m good for awhile. Looking forward to some relaxing time with the music. Very pleased!”

I only have experience with a few amps but certainly can vouch for this one (in my room, Schitt Bifrost Multibit DAC, Airport Express streamer with Wyred 4 Sound Remedy Reclocker, Signal and Blue Jeans Cable). Glad to hear why I’m seeing Dynaudio and Octave together in a lot of photos online.   

PrimaLuna would be my suggestion. I have their pre-amp driving 2 of their mono blocks. Very happy with sound, build quality and looks.
