You might take a look at Shanling, if they sound as good as they look.....

The VTL would be a strong contender. I don't think The Shrimp has a remote. I believe Rogue Audio also has a higher power integrated.

Audio Research has a 55 wpc integrated, I think it was VT-55. I heard this amp with B&W and with Martin Logan. I didn't care for it personally.

You could probably find a used Conrad Johnson MV60 or 60se power amp and one of their preamps used for $3k. The MV60 is EL34's, the SE is 6550's. Of course, the CJ would be my preference.
