Class A, A/B vs Class D amp Soundstage

Of course, nowhere in this discussion is the general thoughts about the speaker impedance, and that this is a tiny integrated amplifier that might just be mismatched to the speakers, or that this is otherwise an entirely new device vs. the original.

We’ve simply thrown out all Class D because one very small integrated amp didn’t cut it.  Never mind that in all classes of amps, different amps have different output impedance curves so amp X may perform well with a pair of amps but amp y may not.

Before you throw out an entire class of amplifier altogether you need better control of the testing, and to use multiple examples of Class D.

Otherwise, if it was me, I’d say all Class A was crap because I heard one brand of Class A amps and it hurt my ears.

I’ve owned PS Audio class D. It was a must to leave amp on 24/7. If amp was put back in the system it could take 3 to 5 days before things sounded correct again. A/B amps would take maybe 24 and at most 48 hours and class A tube a few hours. Why class D took so long was a shocker the first time I discovered this.

I agree with Erik Squires suggestion of checking out NAD Class D amps, but Zlone also nailed it on three separate items being changed by going to the CA all-in-one. Did you consider the all-in-one offerings by Naim? My Seattle Dealer carries both the EVO models and the full line of Naim all-in-ones and steered me clear of the Cambridge offerings if I could somehow go with Naim [even if used over new for the Cambridge].

The Naim all-in-ones are not Class D, however. NAD does have all-in-one offerings with Class D.

I’m not that familiar with the Cambridge models you speak of but be careful lumping  all Class D amps together.  I own the Atma-Sphere Class D amps which I have directly compared to my Conrad Johnson Class AB amp in exactly the same system (like you did).  The CJ amp although older is no slouch, but the A-S amps are still better in soundstage and all other respects as well.
