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?

I'm using a Peachtree GaN 400 with Tekton Double Impacts (98 db/4 ohms), and I'm really liking the sound, especially with the addition of a tubed Rogue preamp.

I am running Peachtree Nova 300 and Harbeth 30.1 24/7 with no probs at all and electric bill is almost un impacted. With a little effort -cords, ethernet- it sounds really good.

To try, best is go for Aiyima's offering(official store) in Aliexpress they are below 100 USD and has got very good reviews at ASR testing.

I would consider the PS Audio s300. I like the sound of the M700s on my ML electrostatics.

I ran the LSA Voyager GAN class D amp into Spatial X3 high efficiency speakers.  This pairing sounded great.  The top end extension may be a tad better than the superb Coda#16 class A amp that replaced it.  However, the midbass and low end was not as good as the Coda.
