I use a combination of NOS and European manufacturers. I use the Russian Electro-Harmonix 300B tube for the SET amp. I have no complaints either aurally of of it's measured distortion spectra, which drops off like a rock after the 4th harmonic. The input 6SN7 for the SET is a NOS GE tube.

I usually don't get too wrapped up in tube brands. If I don't like the way something in my system is sounding, I can design it, or redesign it till I do.

I have a few SACDs, but honestly like the sound of vinyl stereo LPs better than any digital commercial release I've heard, in any format.

I have a recording preamp/mixer I made for making live recordings, and this, in combination with a modified digital audio workstation (ProTools), yields digital recordings which can hold their own with a vinyl release (and are better in terms of low end response and noise).
