+1 @ghdprentice . In my den I have a pair of Kef R11 being driven by PS Audio M700 monoblocks. I took a pair of Audio Quest Rocket 44 cables cut them in half and am biwireing. The bass has improved so much I have turned off the sub. Big improvement over 8ft runs. I would also use RCA and an adapter to another pair of equivalent RCA of 10ft. Try to keep them clear of other cables. If it sounds good then spend the coin for a better pair.
Need 25 foot interconnects
I just moved around my equipment so that the rack with the preamp and digital sources is on the left side of the room and the monoblock amps are just behind the left speaker on a short platform on the floor. I’m using a 15’ RCA interconnect right now, but want to move each monoblock to just behind each speaker — which means I need a longer cable. The monoblocks are unbalanced RCA input only but my preamp can do balanced XLR or unbalanced RCA out. Would a balanced XLR cable plus an XLR to RCA adapter work for this setup and be my best option? Or should I just get a Belden (or similar) 25’ unbalanced RCA interconnect? Or is there a better option?
