Anyone permanently convert from tubes to SS?

No. I have three two channel systems. One uses a tube amp and SS preamp, the other uses a brute, class A SS amp with a tube preamp, and the third uses a SS amp and tube pre-amp. They all sound different but I like all three. I love the rounded, warm, involving Music Reference tube amp sound coming through my modified, stellar, and cheap Parasound pre-amp. I also "love" the sound of my Vincent (Sheng Ya) 300 wpc monoblocks coming through my glorious, heavily modified Air-Tight tube preamp. Not sure which I would pick if forced - so since I am not forced, I don't pick.

Rwwear, you bring up a good point. . . seems though that, in the common lore, SS has ended up denoting almost any circuit with no major moving mechanical, electronecanical, electromagnetic, optomagnetic, parts, no vacuum tubes, and no old style ferrite core memory. So, where do we place switching amps in the taxonomy?

I can live with the Class A Pass Aleph and XA.5 series of amps - they are the best SS I've heard, though I suspect I would also like the Ayre gear as well. I own an Aleph J, but will always keep a tube amp as my primary amplifier. Having both is good, but if I could only have one, it would still be tubes.

I did the tubes and Klipsch thing, then I heard B&W's and switched to SS. Musical Fidelity preamp with Bryston and Classe amps. No tubes needed.

"If it has no moving parts it is a solid state device. A tube amp moves electrons though a vacuum"

....I think I will move my electrons thru air to the nearest bar there they will became static and unmovable for receipt of a vodka-tonic with flashy positrons on the side, dragged by the dranken bartender with very sold and state credentials.
