I auditioned both in my standmount speaker’s odyssey. Both are very fine performers with very different sonic signatures in my personal experience. Hence, a more careful system synergy matching exercise in final selection is strongly recommended IMO.
I chose the HARBETHs .….
My personal experience in MY system ( emphasis added) [ REGA OSIRIS integrated amp, REGA ISIS VALVE cdp/dac, MOON 280d MIND2 network player/ streamers / dac, PHILIPS 673 fm tuner, all CARDAS CLEAR cables loom]
-Both speakers crave high-end upstream electronics to perform at their max. Both will graphically expose any warts or compromises
-The DUETTOs are comparatively more forward and top-end brighter. The 30.2 XD’s are smoother with a sonic and musical coherence of the 2 drivers that is exceptional, with a class-leading midrange . Since about 80% of your music resides in the midrange , if you get the midrange right, everything else will fall into place. Get it wrong, and all the king’s horses…
- It may not matter much in a near-field listening arena, however otherwise standmount speakers are limited by physics in reproducing the frequency response bottom octave . In a larger listening area venue, consider Introducing a quality high-end sealed subwoofer with high-end inputs worthy of the HARBETHs ( think bottom firing ATC C1 MK2 )
- Speaker cables: I don’t drink any of Alan Shaw’s KoolAid that cables don’t matter .I started out with my incumbent Ag-over- Cu NORDOST FREY that were now too bright for me with an annoying emphasis of digital “edge” or “glare” . A worthy upgrade fix was met to an all-Cu CARDAS CLEAR loom.
TAKEAWAY :. Some drive Fords, ….Some drive Chevys ….choose wisely.
