It depends on sensitivity of specific unit to cable change. Tube gear is typically most sensitive, with older, simpler designs being most sensitive.
XLR cable placement
I just bought a new (used) XLR that may possibly be my best cable. Right now I have the same brand XLR's going from my DAC to my preamp as well as going from the preamp to the power amp. My power amp only accepts XLR's.
Would I be better to place my new best XLR's between the DAC to the preamp, or the preamp to the power amp?
Thanks in advance
