Class D with high efficiency speakers

I'm currently running PS Audio BHK Pre / Atma-Sphere S30 Mk3 OTL into Avantgarde Duo Omega horns (107dB/W 16ohms). I've been very happy with the sound of the OTL's the past 12 years and since retiring have been listening to my system throughout the day as well as evening. This is obviously impacting valve life (although Atma-Sphere amps seem very kind on valves) and my electricity bill.

I'm therefore keen to explore whether any of the new Class D amps would be a suitable match in my system.

I've seen a lot of reviews where Class D amps are feeding low efficiency / low impedance speakers and I can see the benefit of their ability to supply current etc.

My question is, does anyone have any experience of running a new Class D GaNFET amp into high efficiency / high impedance speakers?

The Avantgarde Duos have self powered sub woofers so low bass performance of any amp will not be a factor. They are amongst the most revealing, most dynamic speakers ever made & until you actually listen to them properly set up with top quality ancillary equipment, most will not truly understand what they can do & how great they can be.

I powered mine for years w/ an Art Audio PX 25 tube power amp (5 watts / side) & it was truly magical at any volume. They will be a real test for a class D amp & any shortcomings it might have. I’m very curious to hear how that all turns out.. please keep us updated. Thanks
