I used to run class A triode tube amps but the class D amps are just as smooth and involving. I don't miss anything about the tube amps I used prior- the class Ds sound very similar but are slightly more transparent.

Some class D amps will sound great and others will sound like a joke. They are not all the same IOW.

Exactly. As I said in my earlier post, a first-class Class D will match or better any other amp. I decided to move from valve SETs to Class D and am del8ghted not to have lost any of the musical enjoyment I want from my system.

Ralph, Thank You for the info. I will look more into getting a nice Class D amp for my 2 way DIY horns.

  Really helps with horns as you well know :)

    I will need that too since the speakers will be around 97-98db. I just want something lite and will break my back moving them when need too.

      My horn speakers are 107 dB, so even the slightest noise isn't welcome.
      
      I have the choice of 2 Class D amps - Purifi Eigentakt in my NAD M33 (built under license by NAD with Purifi-approved enhancements) and Ralph's Atma-Sphere Class D mono amps.
      
      Switching between the 2 with volume adjustment for the A-S lower output, I'm at a loss to decide which is better. I'm hoping that a better source (likely to be the new NAD M66) may hopefully reveal the A-S amps as the winner.
    - That's the same efficiency as my speakers - Ralph 09:35:19 04/24/24 (1)
      I have to put my head in the mouth of the horn to hear anything when the system is at idle.

        and what I'm looking for from a speaker amp combo on top of best SQ.
