Looking for advice on speaker cables for proac d38 and arc ref 150


Just replaced marsh 400 with arc ref 150. My first and hopefully last tube amp. Currently using MIT mh750 bi wire speaker cables.

Thanks for comments. I'll probably try to demo some of the suggested cables over the winter and see if anything is significantly better than my mh750
M.I.T. Transparent, Audience- will be an excellent place to start- narunner2

Keep me posted & Happy Listening!
MIT MH-750 are some of the best speaker cables ever made, period. Huge, warm, dynamic, effortless sound. None of the recommendations will be superior.

As an alternative, my only suggestion would be to try van den Hul D-352. It has that same huge effortless sound with even more bass extension.
