Good Suggestions for Tube Amps under 6k

OP,

I completely agree. The musical nuance you get with good quality tube amplification is hard to meet with solid state. Once I went to tube amplification there was no going back.

@jonwolfpell Just fired up the Rogers High Fidelity EHF-200 MK2. 

WOW. And THANK YOU! You can get some sleep now:)

Out of the gate I installed some NOS Telefunken EF86 tubes (Roger said don't waste money on expensive 12AX7s so I didn't). So I expect the sound to get even better. But the head room is pretty much unlimited now.

It’s a great amp & built like a tank. Enjoy !! 
 

Thank you  Roger Gibboni for your excellent work.

EL84 based mono blocks.  Sweet, quick and dynamic.  There is a pair at bigearstereo.com for not much.  4K used.  Best of luck with your search.

In my experience, there is a spacious dimensionality in high-quality tube amps that I never quite hear in SS amps of the same caliber / price range.  Texture and tone, particularly in acoustic and wood instruments. Also, the assured warmth without loss of lucid definition. And today's good tubes don't suffer from labels such as "slow," "tubey" or from any background hiss. Certainly, SS is easier to manage at all the points we all know... I went from British SS amps to tube amps a while back, and it's hard to go back.  But I'm always listening for good SS as well... Recommendations?

@gregjacob There are class D amps now that fit that bill.
