Ayre <--> Parasound <--> Pass : where are you?


I’ve been thinking a little bit about three different types of SS amplifier sounds. I’m not really sure what to call them, but I have a definite preference. Here is the spectrum in my mind:

Ayre <--> Parasound <--> Pass 

On the one hand is Ayre and Arcam. Yeah, fight me, but there are big similarities to the sound. I also loved the Pono and what it did for my IEMs, using the Ayre designed output stage. I wish Fiio would license it too.

In the middle is Parasound Halo and ICEpower Class D modules (I’ve owned both) which to me are identical in sound quality. Clearly I’m happy with them for the price!

On the opposite end of the spectrum is Pass. A sound I really don’t like.

But regardless of which you like, what do you think the differences are?

What spectrum do you use to think about solid state amplifiers??

Parasound amps sound nothing like ICE or Hypex-based amps -- probably because ICE and Hypex (even the hybrids) sound little like a good class A/AB amp.

@helomech : I lived with Parasound Halo A23's (a pair fo them) for months. I built ICEPower ASP 250 based monoblocks. I could not tell them apart under any circumstances. Which is why I sold the Parasounds and kept the high efficiency monoblocks instead.

I don't have experience with the A23s, but if your amps managed to sound like the Halo Integrated or JC1s, then you should seriously consider selling your design as they would be some of the best sounding class D amps available. I even preferred the Halo Integrated to the Devialet Expert Pro (something, don't recall the number, some $30K amp). Surprised that some claim Parasound is thin, that's the opposite of my experience. Every class D amp I've encountered lacked bass at lower SPLs and had a clinical, albeit articulate sound. Unfortunately they had no soul. I suppose they could be good for monitoring purposes - so long as it's at 80db^ for decent low-octave bass.
I have listened to many Class D amps and have owned five different ones. Almost all of them retailed for over $3500.00
And likely had a production cost of about $600. That's the primary advantage of class D.
