I bought 1962 Same Dated telefunken smooth here on Audiogon. What I noticed immediately was more pronounced and nuanced bass response. Everything sounds great but without going back and forth between tubes I can't describe the differences beyond the obvious improvement in bass in the initial listening. It's so good now, I no longer long for tube-rolling.... but when I get bored later, I imagine I may give another tube a chance - just for fun.
