I have both a REF150Se and a REF75SE- outstanding amps. I'm pretty sure ARC doesn't want you to use adapters and I def wouldn't entertain having anyone try to convert them to RCA inputs either. There are lots of guys out there who work on tube amps who confidently will tell you they can figure out anything on an ARC and work on it - in my experience they can't without the schematics- and ARC doesn't provide them to non authorized servicers. Also, Kalvin is not retired and is at ARC and is usually the guy who answers the phone. CAll them and ask them directly about the balanced / adapters question. Trust no one else in my experience.
Audio Research reference amplifiers used with RCA IC`s and unbalanced preamplifiers
I am considering purchasing used audio research reference amplifiers either 150se or 75 SE. My question is this
As these amplifiers are fully balanced and don't have an RCA input, can I use RCA interconnects with a conversion plug from RCA to balanced at the amplifier input and will it work in my system?
I don't have any balanced interconnects and don't want to go through the extra expense. Only one of my three preamplifiers has an XLR output and there's nothing indicating the preamplifier is fully balanced.
I find this balanced/ unbalanced criteria confusing.
