thanks for the responses, all - this was quite informative. i ask as i have just purchased an aesthetix calypso and find it to be an exceptional preamp, however, have read that tube rolling with particular NOS tubes can make it even better. i was considering telefunkens, but was curious as to what it was specifically that made the old tubes sound better. sounds like there's some lore/nostalgia, some materials, and some design (component and tube) that factor in here.
Why do old tubes sound better than current tubes?
just wondering, is there something in the design, materials, or fabrication that makes old tubes sound better than those being currently produced?
it seems nearly universally held that old tubes are superior sounding to those made today - is there something specific about the old tubes that make then sound better?
