"@noble100, f.y.i. In a recent test of various class D amps by someone we know in the business GAN amps did not come out top but were pretty high up. The other D amps were cheaper. My advice stick with your NC1200 module amps."
Sorry about the delay in responding, I had stopped following this thread but just checked back.
I've haven't heard a class D amp using the newer GaN transistors yet, I've just read some very positive reviews on a few amps using them. I'm not an electrical engineer or amp designer but it still makes a lot of sense to me that these very fast switching transistors are likely to only improve the performance of any device they're deployed in.
For example, I've read that GaN transistors are capable of switching so fast they literally eliminate dead-time and any resulting distortion caused by it. I would imagine that any good amp designer would believe that substituting these for the typical FETs used would result in significant improvements in the sound quality of any class D amps, or really any solid-state amps, that they're utilized in.
I'd prefer to personally compare some good class D amps using GaN transistors to my current D-Sonic M3-600-M class D monoblocs, which actually utilize Abletec ALC-1200-1300 and not Hypex NC1200 class D power modules, before passing judgement on their sound quality performance. I'm willing to pay more if I perceive these new class D amps as sounding significantly better
Thanks for the info,
