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??
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.

Looks like Esoteric has moved away from class D in all of their current amplifier designs. What exactly was the class D topology referred to as “MSW Pure Class D power amplifier” in the legacy Esoteric integrated amps?
I find many of the comments about class D topology to be counter to my experience.  Yes, not many years ago, it was a new and difficult topology to execute well.  That is no longer true.

I own parasound gear (halo A23 and P3) in one system.  It’s good but not great, but nice from a performance/value standpoint. In a newer system,  I own NAD Masters series which is class D.  The NAD is in another league relative to the parasound as it’s more musical, smoother, more revealing. Of course, it was also a lot more expensive.  
However,  I also own the PS Audio Stellar stack in a third system and it’s shockingly good for the price. (It might be as good as the NAD but they’re in different locations so no comparison can be made).  It’s very smooth, very full and very nice to listen to on speakers that can be very unforgiving too. The Stellar stack replaced a class A/B amp topology and a very well regarded DAC which together cost 2x more,  and the improvement was immediate and significant.   
The claim that companies are making class D because it’s so cheap to execute is just plain wrong. Yes, there are cheap, poorly executed examples, particularly in HT.  But this can be true of any topology, including class A, SET, class A/B, etc and there are myriad examples of poorly done versions of each.  
I will also say that I went out of my way to evaluate class D because I wanted these newer systems to be more effecient to reduce their environmental impact.  Personally, it seems to me we should be pushing for more class D gear and should begin to steer away from class A gear (whether tubes or SS).  There are now good sounding alternatives available.  

My $.03 (inflation)
I recently removed a Lyngdorf 2170 from my system and replaced with an Ayre A7-XE which is a very affordable fully balanced integrated amp.
I have heard some say oh its only 60 watts it will never drive my speakers and I guess that could be true of some very inefficient speakers.
This change opened up my analog front ends ( vinyl and cassette) and really allowed them to shine both in mid to upper low bass and vocals, acoustic guitar and piano.

Right now I have never been as happy with my sq, this little Ayre most definitely rocks.
And I have yet to exceed 45 on the volume and that drove my Triangle Altea speakers to 95db spl
