My concern with this upgrade was the designer posted .47uf was the suggested lowest coupler cap to use due to the possibility of the output interconnect being exposed to electromagnetic fields, many of which can impose hum through capacitive coupling. I had also read that with resistors after coupling caps like the Eros has, bass will roll off with use of lower value caps. Jeff was very patient with my concerns and explained his doubt that the .33uf coupler would be an issue for me. You just don’t get a hopeful guess, Jeff really knows his way around crossovers and circuits and explains why.
He even offered to cancel my order and send the .47uf but I trusted him and went with the 33uf. My pre amp SE input impedance is 300k Ohms.
My system is diy heavy plinth/heavy platter Lenco idler drive - Advanced Analog MG-1 linear air bearing arm w/ Ultra P arm - AT33PTG/II cartridge (.3mV) - Phoenix Engineering BETA 25 watt Eagle Digital Power Supply w/ RoadRunner Tachometer - Park’s Audio Budgie SUT (CineMag Blue 1:8 / 1:16 set at 1:8.) - Bottlehead Eros - ARC Reference 3 pre amp - Krell KSA-250 - Salk SoundScape 8 speakers - NHT B-12d subs (10,000 cubic feet open listening area) - GIK acoustic treatments.
I used my Granite Audio MC phono burn in CD to put some hours on the Eros before the weekend after installing the Sonicap Platinum .33uf couplers. I am very happy to report the 33uf couplers have introduced no noise in my system. Low level listening is greatly improved. My vinyl is more transparent than before. System is more coherent, and exhibits more realistic ambiance and air. There is no roll off of the bass. I am very pleased with the Sonicap Platinums! Thanks Jeff!
