Yup, it’s got to be low, when it get shorter it gets lower, pretty simple.. :-)
I’ve never heard anyone say "make one longer it makes no difference"..
Like I said it’s not hard to make good RCAs. If they are already good, you’re not going to make them sound worse or add some flavor unless you use crap solder and crappy terminal ends. You can make good cables better or worse..
Pay attention, you’ll be fine.. Are you running a low output MC cart? It can only get better unless you make it worse.. LOL
Choppers remorse.. Be bold.. Go for it.. :-)
