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.
