Anyone compare the following Class D rr D-hybrid amps
I owned an S300 briefly, and had the opportunity to perform a direct A/B comparison against the NAD M22 at my local hifi store for several hours.
We used an NAD M12 as a source (playing files from a USB thumb drive, as well as streaming Tidal), along with PSB T3 tower speakers. Fully treated listening room.
As much as I wanted to love the S300 (especially since I had gotten a great deal on it as part of the PS Audio "beta tester" program) the NAD came out on top. This was about 6 months ago, so I can’t recall specifics but I do recall the M22 had much more detailed, yet smoother presentation. S300 and M22 both had powerful low end, but M22 bass was better controlled.
On the plus side, PS Audio customer service is top-notch. I returned the S300 for a refund, purchased a used M22, and never looked back.
It’s possible that the S300 wasn’t fully burned in, but I believe it had 100+ hours on it. Also of note, the NAD retail price is twice that of the S300, so it would be expected for the NAD to come out on top.
