I do that in reverse, pro deck. No idea what you are thinking about tape noise. You can’t increase the 65 db @15 ips without a compander.
Just a thought here but,,,,,,xlr adapters?
My OPPO UDP205 used as a DAC has XLR output sockets. the rca outputs are currently being used.
My Revox B-77 has RCA inputs and outputs.
My pre-amp Audio Research SP-9 MK III, RCA inputs
Recording speed, 7 1/2 ips. 10 inch reels.
I was thinking of XLR adapters for the Revox's input / output to help with tape noise not so much from the dac but to the pre amp.
Any thoughts? suggestions? constructive criticisms?
