Is an unbalanced preamp a bad thing?

I am borrowing a Conrad Johnson preamplifier and it sounds very nice but to my surprise I couldn't use XLR cables.  If I wanted this preamplifier I would have to go through all the torture of selecting new cables versus XLR cables I already have.

Fortunately I don't need extended Cable runs and it's supposed to be a really good preamp so maybe I'll buy one.

Also borrowing some very nice speakers called Magico and will listen to these for a while until I have to give them back.  It's nice having friends who have Nice gear.

And there in lies the huge challenge manufacturers don’t really explain it very well. They say it’s balanced but then again is it really truly balanced for purposes of determining if it’s better to use XLR’s or a simple RCA connection.

This is why people can’t stand buying new equipment with these stupid challenges.

Conrad Johnson I guess makes a really good product but they don’t use XLR. The streamer i use recommends XLR, a lumen. So wtf should you do? I guess you need to buy really good RCA cables to address any deficiencies. And the rabbit hole gets deeper
