Sugden Amps

Check out the Heed Obelisk.  50/wpc, smooth but detailed and the distributor recommends you always leave it on. A very good amp. I think it’s about $2k. 

A somewhat below the radar audio manufacturer is Odyssey.  I own a couple pieces, Tempest/ Kismet combo ... always a rarified listening experience ...

I feel you.  I've  owned lots of high end tube gear.... enjoyed it all.  But, for me, enough with the hassle and cost of tubes.  I also converted to active speakers and the tubes were simply too slow for my appetite for dynamics and immediate attack.

That's my taste in musical reproduction, not to be inflicted on others.  Sugden pieces tend to be quite dynamic and blindingly fast on attack.  Bass is quite controlled, but not rumbling; black background, imaging respectable, not disappearing and holographic.

I've owned/own several Sugden pieces and they all perform very well.....for me.

Hope that helps.

Yes every response is very helpful…

You should also consider unison research their unico line are hybrid amplifiers with tubes in the i put stage with a Mosfet output stage
