That was a good one!
Just finished making mine an hour ago... 5x2,5 mm, solid copper (5xAWG 13 for the yanks) 50 m set me off $60 plus $30 for the connectors. Already sounds better (or not, still haven’t decided) ... Any improvement is probably due to line-level cable routing - less noise.
Edited for missing info.
Is that a typo or did you really mean 50 m (as in meters)? Are your speakers in the same house as your amp?
