I love the sound of my Cary SLA 70A Signature Class A PP EL34 amp with Mundorf Silver/Gold coupling and Elna Silmic bypass caps. It easily surplanted a Krell KSA-50 I had which was grainy as hell and actually generated more heat than the Cary. There's nothing like tubes if you want to enjoy reproduced music.
I'd hold onto this amp even if I upgraded, but I see no reason for that at the moment.
