150b xlr or cinch

Hello
as the title says what is the best connection to get the best sound
via xlr or via cinch to the amplifier
thanks for the information

Generally, a balanced connection (XLR) should have lower noise than unbalanced.

Which noise exactly on 1-2m proper sonic cable?
The difference is how RS and the pream are internally designed, balanced or unbalanced. Out of this, the best sounding connection will show up. Having unbalanced topology and then converting it to xlr for connection purpose makes sound worse than using simple rca. This is valid for any gear.

correct, the whole chain must be balanced, it does not mean that if it has xlr connections it is really balanced, of course. I have the pathos logos amplifier mk2 and I think it is really balanced, but is that also the case? for the rose 150

I’ll go for xlr. It sounds better to my ears.

Generally, not much. I try to avoid gear that has fake connectors though.
