Well,
E-mail works, but not consistently. You have to e-mail 2-3 days in a row. I understand, that Mick is not back into Supratek full-time, so, he's busy doing other things.
Also, my understanding is, that he's not making Cortese and Grange at this point, and only Chenin and Syrah.
My case was something different. Mick and I had some unfinished business since the old days, and to his credit, he did fulfill it faithfully, by making Chenin Mk II for me.
He also indicated, that Mk II Chenin and Cortese are identical schematically, the only difference being balanced outs on Cortese, and more robust PS.
I'm finally using new Chenin in my system, which had been completely redone- I will update pictures later, and now I can make some preliminary comments- it is very dynamic and transparent, I think it alleviated one fault, that was a problem in my system with the first generation of Chenin- some degree of glare on certain recordings.
My speakers now are Avantgarde Duo Omega G2, which are extremely revealing, and I haven't heard any of the glare yet, neither with digital, nor with vinyl, as a source.
Mind you, I'm temporarily using my HT solid state amplifier, Butler 5150, waiting for a delivery of Art Audio PX-25, and so far, I'm really captivated by how the system sounds.
I'm also not using any support system under the Chenin, just stock feet.
