GaN-based Class D power amps
worldwidewholesales Hi, you keep using this word "testing"??, yet I've never seen any measurement "test" results. Or are you just listening? If you are doing measuring "testing" can you let us know what measuring equipment you use?, as there is no mention of it anywhere on your site and if you do, do you have a link to the test result graphs?. Cheers George |
George, Measurements mean very little......you must listen, listen and listen some more.....for reality. Of course, really bad measurements are usually detrimental......however, what constitutes bad measurements? You would have to listen to determine that. I think GaNs will make class D better (everything else being the same). However, we are in the infancy of their use. Every GaN and every mosfet based class D amp will sound different as everything you do makes a difference sonically. We have years of perfecting yet to come. These first GaN amps are just the tip of the iceberg. We will see relatively inexpensive GaN amps that blow these expensive first offerings away......no doubt. Cannot wait for Worldwidewholesales to finally tell us their comparisons of all these GaN and non GaN (mosfet) class D amps. |
Here is a an email back to me from the US company "ClassDAudio" regarding the use of the new GaN Fet technology in any of their completed amps or very well priced Class-D kits they make, that use linear power supplies!! https://classdaudio.com/amplifier-kits.html "Hi George, Cheers George |
Measurements mean very little. I’m sick of ill the informed, saying this, all amp designs, are measured, bench tested and listened to, in that order. ANY!! amp worth it’s salt is designed using all the EE laws of electronics, and then measured/bench tested and listened to. If necessary then to change the sound, using EE laws again, modded, re-measured, re-bench tested and to make sure all is fine, then listen to again. Anyone selling you an amp and saying it wasn’t designed and produced using these, I would walk (no run) away from, as he/she will be a voodooist and or snake oil’er. |
I’m an utter tech dummy. I have no idea what “Fets” & “Mossfets” do & I have no idea if this GaN technology improves the amplifier side or the switching power supply??? ...but I did hear a Marantz PM-10 the other week & thought it was superb. Powerful sound (200w>8ohm, 400w>4ohm) with real clarity. It has a toroidal transformer, https://www.marantz.co.uk/uk/products/pages/productdetails.aspx?catid=hifi&subcatid=amplifier&am... Anyone here heard one? RRP in U.K. is £8k, but they’re going used for £4k. I’m very tempted to go for it. |
