I do have a decision to make concerning the cabling . All my equipment is unbalanced RCA's execpt the SIM AUDIO W5 power amp that has both XLR and RCA inputs but not my other amp the Dussun V8 that only has RCA . Is it wise to have the SIM (will handel the highs ) connected with XLR and Dussun (will handle the Lows )with RCA , or is it better just to ignore the XLR and only use all RCA's ?
