Slowhand -
I apologize in advance. I can't answer your question about any of the Supratek power amps. But I do have a few comments about your Sanders Magtech, if you'll bear with me.
I have not owned any of the Supratek power amps. And, given Mick's keen ear and vast experience I'm sure that they would sound every bit as good as his wonderful preamps.
But, I also own a Supratek Cortese and, until last year, owned the predecessor to your very fine Sandersound Magtech. Mine was an Innersound Electrostatic amp.
Roger Sanders is a talented engineer, designer and builder. I found the Innersound Electrostatic amp to be absolutely brilliant and would still own it, except the protection circuit Quad puts into their ESL 63 family of speakers was death to that power amp. As you well know, Sanders designs his amps with those enormous reserves of current, so they perform beautifully into very demanding loads. Imagine what happens when you "crowbar" the speaker and the amplifier essentially dumps all its power into a dead short. Right - it damages the circuitry inside the power amp.
The current-dumping amps built by Quad are similar in design to the Sanders/Coda Technologies amplifiers but are designed to withstand the ESL protection circuit, so that's what I'm using now.
I plan to keep an eye on this thread to see if anyone can speak to your original question. In the meantime I can't help but think your current electronics perform pretty close to state of the art. I love my Supratek and am a big fan of Roger Sanders work. And it represents tremendous value for the level of performance it provides.
