Atmasphere - thanks for an informative answer, as always. I am not sure about the Dream Maker speakers, but it may be that they are designed for high output impedance from the amps (like your speakers) so that class D might sound a bit lean, compared to more beefy OTL sound from the MA-1s. Not sure, have never compared. My gut feeling would be to try class D first in a smaller system.
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?

@evank have you had a chance to try the Starkrimson amp with the Zu speakers? I am interested in hearing your thoughts. |
