greywolf  As far as pure stats go, not one spec you cite beats my 30 plus year old Audire amps and preamps.  ERGO:  That would not be the reason to change.  I would certainly presume this amp sounds better than my relics, but I did have some very fine Classe amps and preamps given to me, and they were not as good sounding, not because of any specs, but because of a feeling of the sound being artificially faked to spread out everywhere.    Maybe you should just enjoy the music. 
greywolf  Upon a bit more pondering, I don't think those are not even good specs.  The THC is not even with a full range signal, and double my Audires. The frequency respoonse is down a decibel at 20,000 cps, vs my 1- 100,000 cps that is flat to well over 25,000 cps.  I bet the Classe you have is better, at least on paper.  The signal to noise ration is nothing special, being a full 10 db worse than the 30 plus old Audires, and more akin to an almost 50 year old Phase Linear.  It may sound awesome, but not because of those specs.. 
Specs are like the ingredients list in a recipe. They are just the starting point.
Give 3 different good chefs the same ingredients, and I guarantee you'll get 3 different tasting meals with 3 different presentations.  
somewhere in this thread "hearing" became inportant....so I made a Dr's appointment 3.10.2021 at 3PM  to check my hearing .
Afraid of what I might find out .
My "wife" and audio engineer/recording artist "son" both claim I have hearing issues .....
So I might find chasing  this holy grail will be forced to take a left turn instead of a right. 

@firberger

could you please repeat what you said... couldn’t quite hear you... now i am onto my next $10,000 amp review 🤣

seriously, good luck at the ent doc... 🙏
Thank You @jjss49 . I will be giving an update tomorrow - or Thursday .
Stay well :) 
More power to ya if you can be happy listening to a 400.00$ amp.Good luck you’ll need it.I wish I could.My ears craved better sound than that when I was 14 years old,mowing lawns to feed my addiction to Hi-Fi. After 40 years I’ve spent about 250k.My amplifiers now cost 13k more than the last three year old used car I bought.So if you can be happy with a 400$ amp, or a lifeless digital amp,you should consider yourself lucky,and or deaf.At least you’ll have some money left over for good hearing aids my friend.

Happy Sunday already :) 
Hearing test was a success - No further reduction in hearing from 2014 test. Still a roll-off at 1500 thru 7K . Women and children are often in that range.  Bottom end-not so. Will look to add a new SUB soon :) 
Doc says a hearing aid is needed when my friends are no longer inviting me to discussions because I no longer contribute to the conversation because I miss to much of the dialogue.  
@firberger 

excellent -- happy for you -- good you checked, as scary as that prospect may have been ---

now you know if your system is sounding not so great it isn't your failing hearing hahaha !!!!  

enjoy!
"....Examples abound: http://matrixhifi.com/contenedor_ppec_eng.htm  It’s no use saying “but I can tell”. All these guys thought that too..."

You guys are like a cult of Dr. Toole. You keep posting this "test" that uses shitty little 6 inch monitors and nobody hears a difference. No surprise there, that system is almost a Best Buy bargain special. You guys have to stop embarrassing yourselves. The REAL test is in your own system with your own source material and we aren't using 6 inch two ways.... 
The Parasound Halo JC5 tamed some of the brightness that I had with the Classe Sigma 2 amp.
Definitely an all around improvement. More musical, better bass control but it did loose some bass punch.

Then I switched XLR interconnects to Mogami's made by Jerry of 10 Audio. This was a big improvement. Detail, clarity and bass improved. I highly recommend them for $109 for 1 meter pair.

To me the amp and the Mogami XLR's ended my search for improvement. My system sounds great to me.

FYI
I was using XLR's by Raven Audio. Jerry cables are listed here on Audiogon.

My system:
NAD C 658 Preamp with HDMI module.
Parasound Halo JC5.
Audioquest NRG-Z2 Ac power cords for pre and amp.
Velodyne HGS 10 sub.
LG 65 inch TV.
Logitech 665 Remote.
Arcam DVD/CD.
Mogami XLR's By Jerry at 10 Audio.
