Gee, 30 wpc. Maybe I want to hold off modding the Teac. But I suspect that this one will cost more, especially if Vinnie has to build it from more of a ground up basis.
My vote for options/enclosures:
Two cabinet options:
Plain black ala Clari-T;
Fancy ala Lotus.
I don't know how much money/hassle the wooden cabinet is, if it's close to the metal case I'd drop the metal. OTOH its the front that is the money side, so maybe a wooden front is all that's needed. If the power supply is in a separate box, I'd leave both plain and provide a longer power cord so the power supply box can be out of site and/or out of the way.
Four performance options (in any combination):
Base;
Battery;
Battery with A/C ala SB2/3;
Fully tricked out (volume control, internal wiring, auricaps, black gates, input/output upgrades, etc.)
I don't know how much cost will be involved to build a "base" unit, so perhaps only a fully loaded version is appropriate. But with the Teac availablity drying up, a cheaper version would be good. As labor would be the same to build base or loaded, maybe these options don't make sense. But I do like the A/C option as casual listening represents the the bulk of the time my system is on.
