I have heard that there are third-party manufactured umbilical cords for the SP-11 MK2 (the cord that connects the power supply chasis with the preamp chasis). Does any have experience using them or know where they are sold? Thanks!
I built some of these over a decade ago.....I spent a couple years rebuilding the SP-11, gave up and sold it....I liked the late model SP-10s and the SP3A-1 with updates better than the SP-11....
Check the Great Nothern Sound web site. I think Steve does this sort of work. I think I have seen one other source for this but I'll be damned if I can remember it.
Thanks, Maxgain, I found the web site!! They do offer umbilical cord for the Audio Research preamps. They claim to improve the performance, however, Rene's comments makes me wonder if it is worthwhile at all.
