Dvdgreco, I just got the EI Elites and find just as much detail, but not more, than the EH I tried prior. As to warmth, agree it is not "tubey-warm" but it is a natural-sounding tube that takes nothing away from the music. Nothing 'cool' about it. The stock Jolida tube will give you warmth but take away a lot of other things.
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?
