Thank You for the kind words Kgturner.
The phenomena of the this tread as well as the number of
people participating and being part of "THE SUPRATEK CLUB"
can't be explain until one experience Michael's (Mick) products first hand.
On the matter of tube choices and its effect on the sound, I am also curies. As much as I would like to share my personal experience with the rest of "S" users - I can't because of my very limited time with the unit. As far as the tubes that came with my preamp, all I can say is that I can not find any shortcomings of that combo. Of course, it is too early for any meaningful evaluation or comparison. What I have noticed is that tubes chosen by a privies owner (NOS Tung Sol-round plate) are very sensitive/microphonic and a use of a tube rings is a must.
Other then that, they are wonderful.
I would also like to ask:
about the preferred way to address vibration control, unit placement (and power supply). I know I am going nuts with all this questions.......one more, power cables/ interconnects - make difference with Supratek or no.
