Long RCA interconnects

Wow that’s a low gain phono stage (42dB/57dB) - so you could be in for some issues if you’re driving a long run off it. The stage itself is capable of driving a healthy 2-20V output but it would be good to know what’s coming in, what cartridge do you have? Hopefully MM or high output MC

I have a Benz Micro Silver MC

OK that's a healthy 2mV output so the phono stage will be outputting 1.4V which is a good signal and should put you in as good a situation as you could hope to drive that long single ended run. If you had a .3mV output (i.e. typical low output MC) things might be more problematic -- anyway good luck!

Don't know of options but 18 feet is very bad news sonically.Good luck though.

Just got in a pair of Kabeldirekt 20 feet pair to test out. Sounds amazing. Just for peace of mind I'll probably end up making my own 'audiophile' interconnects but cool...and it looks like I really need 15 feet or so.
