I concur with Kehut on this; the Ei's are the best value in tubes that are currently in production for this player. I installed them three weeks ago after trying EH, Sovtek LPS and JJ's and the sound keeps better and better as they settle in.
Jolida 100 cdp
I have a Jolida 100 cdp with stock chinese tubes. My system include B&K ST-202 with B&K Pro10MC sonota pre-amp, Alon II speakers. My listening habits include blues, jazz and indy bands. Looking to upgrade tubes to best suite system and listening habits. Are the RCA 5751 triple mica back plates the answer?
