GaN FET Amps vs. Traditional Class D Amps

I've been using a Classe CA-D200 class D amp for years.  I don't know which "type" it is, but I've been very happy with it in my main system.  I admit I haven't auditioned anything else in a long long time (I was using a B&K amp before the Classe) but I don't feel as though I'm "missing" anything. After visiting what seemed like 200 audio systems during AXPONA I was delighted to discover my system sounds pretty darned good in comparison to a lot of the megabuck systems I heard (I know, I know, the show systems are set up in less-than-ideal acoustic spaces). I probably should bring home a big old A/B beast to compare, but I'm experiencing a mix of laziness/satisfaction that makes it difficult to take that first step. My son and I listened to Paranoid Eyes from PF's The Final Cut (2016 vinyl reissue) on Saturday and the combination of microdetails, midrange sweetness (piano) and low frequency slam were breathtaking. 

@atmasphere thanks for clarifying.  

I love the sound of my Technics SU-G700M2, which uses GaN FET.
Takes me to la-la land every time.

All the best,

you know what - my peachtree gan amp sounds lucious, pristine, weighty, pure, etc - but what it doesn't have - is the ability to be musical and inviting

its "I'll settle for this gorgeous sound of my class d amp - but ill sacrifice musicality"

Listen to a more conventional amplifier and tell me its not musical - its a little sloppy - but its not robotic

My Peachtree Gan 1 is as MUSICAL as any of my class A or class AB amps....It's a tremendous value.....Peachtree has a return policy. Try it.  Saying that it's not musical is just not factual. .  I feel it's actually MORE musical than my similarly priced Belles Aria which is a highly regarded amp in the $2500 range.You like ROCK.....It would be a perfect amp for you. Everyone has an opinion......
