The Dude as an output impedance of around 5k ohms. I am having the same noise problem in my system with an Aesthetix Atlas hybrid amp and my Dude preamp. The Atlas has both xlr and RCA inputs however. I get a buzz with both the Dude and a passive preamp -
Lightspeed Attenuator. Seems both of our amps may be very picky regarding single ended preamps and ic's? Al has tried to help me figure out my issue, but I still have a buzz - slight buzz on both speakers. Sounds like some sort of ground loop issue to me.
Strange for sure..For me the buzz only came when I changed speakers from active to passive. No buzz with active speakers, buzz with passive.
System sounds great so I live with it. Can't hear it 10 feet back.
I tried adaptors like you with pins 1 and 3 tied, still a buzz. I purchased an ic that goes from RCA to xlr with 1 and 3 combined, still have a buzz.
I am getting some kind of ground loop issue when my ic's are connected. Any ic's. I may try your transformer answer, but now wonder if their will be an input impedance mismatch with my pre and the Jensen transformer? The Dude has 5k ohms of output impedance.
