This may be bit late. but in addition to my prior comments, Here it is finally . A class D amp that uses a toroidal. and Yes the toroidal is big enough because it is
probably also a hybrid, meaning the power supply is only partial SMPS. This is how you make Class D more reliable. Give it the power supply we are all use to and know and love. The below comment came up in a private message when I was discussing this with another member.
Forum member NYNOT, thinks toroidal amplifiers are dinosaurs. I always argued they are not, and that class D tended to married to smps because of the weight concerns Class D brought with it on introduction. Here is where a reliable Class D amplifier, can be given a more reliable power supply.
Exactly , Zepher uses XXXX XXX toroidal. I always argued this like crazy in AVS threads, even in the "is class D ready for primetime thread. Deaf ears, that you can use a toroidal for class D. Everyone thinks you have to have SMPS , because they don't understand amplifiers. Was just looking at that amp yesterday. Note I also seen another amp like it, where
someone said............ Cant put out that much power the toroidal is not big enough!!!!. Again They do not understand. Bottom dollar, the zepher is a hybrid like the crown xli in the power supply. She will first convert incoming line frequency, to say 1000 hz. instead of way up at 100000 like a full blown smps. Now you can use smaller toroidal for way more power per pound as transformer at the higher frequency can do way more power.
