Anybody else waiting for GaN and Purify to have a baby?

mini 5 received today, plugged into system, at first it sounded pretty chalky, but the sound is taking shape after about an hour in... will let it burn in for 24 h and revisit

btw - system is bluesound node rca dig out into doge 7 tube dac into XXX amp into Spendor SP100 R2 - streaming qobuz hires - might swap in chord m scaler/hugo tt2 at some point for max transparency, removing any tube beautification

planning compare this baby gan with recently acquired agd audion, and longtime reference amps hegel h20, ss arc 100.2 and tubed arc ref75 running kt120’s, all accept balanced-in direct from dac, w/o linestage

its a 15 day trial so i won’t get into swapping speakers or sources much, just keep those relatively constant

I wouldn't worry about it any competently built purifi has distortion and noise way below human hearing for that matter so does hypex and benchmark amps. I have tried different purifi, hypex, pascal and other class D amps and I have never heard any difference which stands to reason as speaker distortion is considerably worse. 
 

Based on @ricevs and @atmasphere discussion, I want to ask a stupid question:
Between GAN and Purifi based amplifier - would there be a big difference in the quality of sound OR do they approach the same sound quality when designed properly?

That depends on the distortion signature, which seems to be more important than **how much** distortion is present. If "designed properly" (IOW having a similar distortion signature) I would expect the same sound quality too. This is simply because most of what we audiophiles describe as differences in amplifiers comes down to their distortion signature.

The "distortion signature" is just one of an infinite amount of things that effect the sound. So no, no two different implementations of Purifi amps sound the same (I am trying two new mods tomorrow on a Purifi amp and I am sure I will hear two new "different" takes). Its the same with two amps with the same "distortion signature". They will sound different for a thousand different reasons. EVERYTHING makes a difference......I state this over and over again as it is my direct experience of testing parts and execution and circuits for over 45 years. You change the fuse in an amp and you have a completely different sound......even though the "distortion signature" remains the same. Believe what you want. I know what I experience......experience is the only valid path to truth. You must directly listen to something to know anything in audio.

"Designed properly".......now that is funny. There is no consensus in high end audio as to what that means. You have the nerd types who say it is in numbers....and you have the subjectivists who believe what they hear.....many of whom....hear different things....he he. In drag racing you can measure the results (elapsed time and speed). In high end audio......what the result is.....is subjective.....totally.....so there is no reference....just beliefs.....some beliefs based on theory and some on experience. I say again.....you must listen to know what is "real" for you.

If all you need is a certain "distortion signature"......then why make a new amp? There are already amps with that signature.....nothing new there. We are constantly evolving.....everything is. We discover more and more each day.....new things that cannot be measured that make the sound better. This is good. When we finally can measure all that we hear it will be a miracle of miracles. Of course, our life is already infinitely miraculous. 60 trillion cells in every human body.....dancing in the light of God.

No one knows what amp will be best in the end......for there is never an end.  I keep modding the Purifi and I will keep modding the GaN amps......they will all keep getting better and better.  I believe, that in less than one year.....high end audio will start to have its mind blown......not saying any more.   In three years....we will be swimming in the infinite possibilities most have never known.   Good stuff....I mean great stuff.....for very little $ coming to your door soon.
