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??

@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. 

@roxy54 - That is my experience as well, even with many speakers, many rooms and many different Pass amps.  Ayre IS very very smooth, and open.

@tomic601 

you lost me when in another thread you called Ayre dark........far far far from dark.....


Feel free to hold that against me until the end of days. :)

Erik, I think there are too many variables to draw any meaningful conclusions relative to the sound quality among these different brands. My anecdotal experience having heard Parasound A23 and an older but comparably powered Ayre amp in the same system was the Parasound didn't even come close to the fullness and organic sound of the Ayre. I also heard the Pass XA100.5 monos in a completely different system and room driving Vandersteen Treo CT speakers and they sounded incredibly transparent, full body and musical. Any input will be completely subjective borderline pointless.

kalali - Well, Ayre remain my favorite SS amps, even if pretty much unobtainable for me. :) 

Best,

I have recently entered direct experience with Parasound amps.  They are very very good.  However, stock, they are definitely a tiny bit on the thin side and somewhat lacking in resolution (to my expectations).  They are VERY refined and smooth, however.  The problem with Parasound is that they fuse the heck out of everything inside. 


The A21 as 5 fuses total:

1 x 15A main fuse

4 x 8A post transformer fuses


JC1s have 7 fuses total:

1 x 12A main fuse

2 x 12A post transformer amp fuse

2 x 1A post transformer driver board fuse

2 x 1A (small) post regulator driver board fuse


Once I upgraded everything to Furutech fuses (my standard), it really resolved the initial "lacking" characteristics.

I have read that the smaller A23 is not even in the same league as A21.  Not sure about this.  Could be the smaller power supply, but it still has at least 5 fuses.
