Which Class D Amplifier? PS Audio, Ghent, Nord, Merrill or other???
I’ve seen various brands mentioned, such as PS Audio, Ghent, Nord, Merrel to name a few, but I’ve not heard any of them.
Which company is producing the best sounding Class D?
Which models should I be looking to demo?
Thanks

Great find. GaN technology for $4k, and this Technics SU-G30 is also a complete network integrated amplifier. Seems like it doesn’t use the 1.5mhz higher switching frequency that the $20k Technics SE-R1 uses, but does use a hybrid power supply, not all smp, and by just using the GaN technology it’s probably front of all it’s competitors anyway. https://img.usaudiomart.com/uploads/large/1837138-technics-sug30-network-amplifier.jpg What one reviewer thought Cheers George |
One day maybe, when the price (not looks) of the performance of the SE-R1 comes down to the the price or lower of the SU-G30. GaN technology seems to be lit, just needs more semi conductor manufactures like Motorola, AD, Texas, ect ect. to purchase patent rights to make them from EPC (GaN) That’s how they (Lidow and co.) did it when they sold the rights to the power mosfet all those years ago, and if you remember the same scenario is going on here. Initial price of amps using them were very high then they crashed because so many manufacturers bought the rights to make them. BTW looking at the heatsinks in the SU-G30 above, that section is the GaN amp, it may have higher than todays 600khz switching because it’s using these heatsinks, as EPC said to me if left at 600khz there is no need for any heat sinking on any of the GaN boards, so it maybe higher. Could be a great sounding little amp, I can think maybe Quad ESL57’s would be nice as they can’t take to much wattage, or any > 90db speakers Cheers George |
