I am seriously considering a tube preamp to go with my SS amp & CDP. I have always used SS exclusively, but these discussion threads are making me adjust my thinking.
What I DON'T understand is : Why are New-Old-Stock (NOS) tubes the only ones that people try to use - especially Russian Military spec? Are there no modern, US-made tubes that work well for hi-fi use?
Is it that tubes are not used in industry enough to keep manufacturing new ones, so we are stuck with tracking down 1960's stock in some forgotten warehouse somewhere in Rotterdam???
