Okay to use RCA adapter on a fully balanced amp?

@orchardaudio that will be tricky for a lot of tube preamps. Our preamps can drive that no worries, but our preamps are balanced so its moot...

@orchardaudio Most preamps can do 5Volts easily as long as the input impedance of the amp isn't an issue! My recommendation is thus to simply try it.

Here’s the part that concerns me about this amp possibly not having a "true" differential input, despite earlier verbiage:

If a balanced connection cannot be used, note that the amp cannot be driven to full power from a 2-volt single-ended output, the limit of most receivers. You leave half the power on the table.

@mulveling According to their website, the amp is fully differential and balanced from input to output. Its a bit hard to imagine, but it is possible that the input stage has a really poor CMRR (Common Mode Rejection Ratio) which would cause it to be more distorted and lower power when run with a single-ended source. But its hard to imagine that they would know to do balanced and get the CMRR thing so bad in that light- although I have seen that sort of thing happen.

At any rate it won't hurt to try! If the CMRR is anywhere near what we've been getting with our amps over the last 45 years it won't be any problem at all.

true fully balanced differential amplifier from input to output.

@blkwrxwgn , you should be able to drive the amp single-ended using an adapter. I would expect that your amplifier would sound the same driven balanced or single ended based on the statement above.
