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

The answer to your question is somewhat dependent on the speakers you want to drive and at what listening levels. That said, there are lots of good suggestions above.

I own an SLI-80 with quite a few factory upgrades. Bought it used in the stock configuration and a couple of years ago had it upgraded. Really like the result. Use it to drive Merlin TSMs (8 Ohm, 87dB); not a hard load, but not an easy one.

Miniature tubes are all NOS. Have tried quite a few different power tubes (one of the virtues of the SLI-80 is the variety of power tubes it can accommodate). Generally rotated between Winged-C EL-34s (triode) and Gold Lion KT-88s (ultralinear) for a few years. Tried KT120s (ultraliner) on a lark and they turned out to be an extremely good match.The clean sound, improved extension top and bottom, and the effortlessness with which they handled the Merlins made them my standard.

Good luck in your search!

Consider building one from a kit If you can get someone to mentor you if you wonder whether you will get it right. Everything you will solder together is large and easy to get to and there are many fewer parts. You will have freedom to make the chassis in your own style and you will appreciate amplifiers more after you learn more about them.

 I would agree with the few people out here that said the Rogue Magnum would be the best especially after you rolled the tubes 

Really nice, dealer demo, low hour VTL IT 85 for sale on US audio mart with full warranty.. I’m not affiliated with sale. I think this would also be a great choice.

PrimaLuna makes a wide range of high quality tube integrated amps to fit your budget. I own a $2k Mystere IA11 (sister company and made by PrimaLuna). Superb build and sound, so consider PrimaLuna available from Upscale Audio, as well as the Mystere brand.
