I replaced the Tube Box II, which I liked, with a used Linn Linto. Far better, IMO. Absolutely not solid-state harsh, but more overall realism. And, no adjustments to screw around with. I have had the Linn for several years and have no desire to upgrade. There is one up for sale on Ebay now, with a bid of $295 as of now. I bet you could snag it for $600 or so.
