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

I have a Primaluna Dialogue HP, paired with Revel F208.  It is a great match, the system sounds fantastic.  You could get a similar result with the Primaluna dialogue for under $3k used.  In fact, being slightly lower in power may give it a bit more finesse.

This is easily comparable to other suggestions, and almost HALF your budget.

Plenty for what you describe as use. It will drive your speakers, and worry free. You don't need a 50-100 watt spec on paper, if you think it won't drive your speakers.

Been using PL products over 10 years.Ignore the import bashers

Quicksilver. Hand made in USA and sounds excellent. 

Without question... the Line Magnetic integrated amps... will amaze you.  Just incredible resolution of detail, clarity, and 3d soundstage.  Those mentioned above are as good as it gets!

The Raven Audio Blackhawk has the best sound out of the box- truly high end rich yet transparent.
If you need more power the Rogue CM II/III can sound nearly as good with some tube rolling of the 5 small signal tubes.  
May have been supporting systems but I did not care for the sound of the Line Magnetic integrated amps.  
The Primaluna sound very good but tend to have a certain flavor to the sound and have too many tubes to deal with for me to bother.
