There’s no definitive answer. Typically with balanced components you will get lower noise floor using balanced cables. The XLR output is usually higher than SE. using matching preamp and amp helps with synergy. If you use different brand preamp check to make sure the output gain and impedance match well with your amp.
And +1 on 1m length. I actually have a 2m set going into the amp - gives me more flexibility.
Diving into balanced
Hi everyone. I’m making the jump to separates and as such am thinking that balanced is the way to go (unless people here say otherwise). If my preamp sits exactly 12" above my amp would you suggest a .5m balanced cable or longer? It seems like it should work fine but i’m not familiar enough with the ends to be sure.
Looking to hear from everyone’s experiences. Thanks!
