I have the HARBETH 30.2XD’s driven by a REGA OSIRIS integrated amp, with a REGA ISUS VALVE cdp/DAC and MOON 280D MIND2 streamer/ server/ DAC source .
MY EXPERIENCES
I. don’t drink Amy of Alan Shaw’s pontifications and force-fed KoolAid that speaker cables don’t matter with his HARBETH speakers. After much personal and hands-on experimentation with many options including, inter Alia, BELDEN, ATLAS, CHORD, NORDOST FREY, VAN DEN HUL and a myriad of other “budget” vablesc I thankfully landed on premium build CARDAS CLEAR REFLECTION speaker cables as best of breed in my system .
I run a full CARDAS CLEAR model cables array in my system, but but I specifically experimented and chose the REFLECTION model specifically for the speaker cables, on the direct advice of CARDAS engineers to tame a room brightness introduced by a lot of large glass windows.
Tthe CARDAS REFLECTION / CARDAS CLEAR loom was a step-up from my predecessor NORDOST FREY full loom . My experience had an audio performance improvement in MY system ( emphasis added) that’s was not subtle.…full stop.
My take:
= each to his own ….experiment yourself and there is no one-size fits all magic bullet solution IMO … carry on ….
and choose wisely
