so thorsten, with those caveats, would your advice be that if going from older chips such as 4558, it might be the go to stick with the 2604 for a noticable improvement without too much work on power supply etc; and plan on getting max sonic upgrade using 6172's when youre prepared to do some associated work??..im thinking of a teac x-2000 which uses the jrc4558 and considering whats in the box vs sourcing?$$$ etc...because ive got a bunch of 2604/604 that have been sitting around for 10 yrs looking for a circuit to enhance. ive had some previous advice that opa2132 would be an almost direct upgrade..and other advice to go with 2604 and some passive reg via choke in the main power supply as well as electro replacement. same caveats with gain etc in record/replay eq areas. I know this is slightly off thread with regard to your riaa pre, but its doesnt seem to be as cut and dried as choosing particular tubes for particular applications...relatively speaking!! your comments?? (btw whats the url for your tube phono...its gone from the ref at tnt??)
thanks.....cb
