Purifi v Gan amps?

In the middle are AGD (Gan) amps with a nominal impedance of 40K ohms, and with international electricity capability.

Ticks all my boxes, which I am a little bit sad about for reasons.

It’s pretty clear both technologies offer some high performance potential.  To me, I wouldn’t worry so much about the technology and just focus on whatever amp offers the sound characteristics you’re looking for. 

I know people who have been using  and building Class D amps for at  least a decade and they do not like the  sound of the Purifi modules.

Amps built with Purifi modules have no sound. 

With reference to my previous comments, they may be coupled with pre-amps or DACs that are unsuitable.  Like buying a car without a tow bar or is solar powered, there is no hope if you want to tow a trailer or a caravan or whatever.

It's all about the implementation, and all the other parts used.  Click on the dropdowns here and see how you can tailor Purifi sound.

So if you ant Purifi amps to have a sound you you use an op amp buffer with a sound?

Why not just use an op amp based amplifier like a LM 3886 and avoid the cost of the Purifi module?If you need more power just parallel multiples of them.

Although from what I have heard Purifi amps do have a sound and it is characterised by by sounding veryclear and detailed but also quite flat/2D and having very poor timing and musical communication.
