Time to buy a class D amp?

Can you read your full last paragraph?

Yes- in rereading it, it makes sense to me...

However overly low impedance can accentuate ringing. I get the impression you would be familiar with snubber circuits? It is similar to a resistor in series with the capacitor. The resistance is needed to damp ringing.

Usually those snubbers you see in amps are for the amp’s benefit, not that of the loudspeaker. But keep in mind almost any amplifier will provide damping to almost any loudspeaker. But the simple fact remains that there is no signal in audio where the ability to stop on a dime is important.


As I just pointed out, once the woofer nears the zero crossing point it will want to keep going for a bit, but once it gets to the zero crossing point whatever signal that allowed it to get there will also be calling on it to continue in the same direction past the zero crossing point. There never is a point where the woofer stops unless the amp is shut off.


So the two points of stopping are:
*a DC pulse, or
* the amp being turned off
In either event no audiophile listens to either so its moot :)

I was thinking more of snubbers for diodes (transformers), but realistically any circuit with reactive elements.  The output impedance of the amplifier is part of the overall electrical circuit and hence the total electro-mechanical assembly and hence impacts ringing/resonance. I guess I made my point poorly ;-)

Hi Tim,
Thank you.  Very well said indeed!

     I've become a big fan of class D amps through research and personal experience gained by using several examples in my own system. But I believe all amp types have their pros, cons, compromises and limitations and that class D amps are not the best choice for everyone.
     I believe it's very important to match the amp(s) used to one's speakers while also considering one's personal preferences and tastes. I understand the truth is that all amp types are capable of providing excellent sound quality and performance results when properly matched to one's speakers but that all amp types are not suitable for all speaker types.  
     I also know that, once an individual discovers a good match between amp(s) and their speakers that performs well and they enjoy the sound quality of or even numerous combinations, I have absolutely no interest or concern in dissuading them from utilizing that combination or combinations.

It's about time to start enjoying music!
 
Happy New Year

Ok I'll bite, which do you prefer the "sound of" forget everything else?

Hi George,

Context allows us to appreciate each system on its own merit.  Let me put it this way: it is like comparing reference-grade analogue playback to reference-grade digital playback.  You stop worrying about sound quality and focus on the music, right?  I am at this point already (within my budget constraints of course).  For the sake of the argument, the AB stereo amp has been driving a pair of Martin Logan speakers for six years, and the D mono blocks have been driving a pair of Dynaudio contours for more than a year.  Both setups reproduce music that engages me, my family and my visitors. No defects, no failures. What else could I ask for?
Wish you all happy listening :)

That went nowhere for me.🤷‍♂️
Would have been nice to know what each amp sounded like driving both speakers, oh well, thanks I guess.🤷‍♂️

Cheers George
