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!
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.
