I will be transitioning my setup at some point next year and face a similar question. I’m currently using a long(ish) pair of WyWires platinum IC’s (13’ single ended) but will need at least a 30’ run in the new setup. The rest of my system is (mostly) connected up with Empirical Design IC’s and PC’s which I have used for decades and never felt the need to upgrade. I reached out to Karl last week to discuss and am confident he has a solution for my new configuration. ED cables tend to fly under the radar but recently won another Editors Choice award from TAS after doing the same in back to back years (2008 & 2009 I believe) FWIW. These are very high quality cables that are reasonably priced and therefore a great choice when you need a long run that could otherwise break the bank (the WyWires are great but considerably more money). Give them a call—Karl has been a trusted adviser for me over the years and is great to work with, customizing lengths, assessing system hiccups, etc.
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?
