Hi Lewinskih01,
This may not be terribly helpful as I don't own one of their amps but I'm a more than pleased owner of the YDA-1 DAC a gorgeous and fantastic sounding piece of equipment. Regarding the amps sorry to hear that your inquiries were not answered but a few thoughts.
Of the 2 amps you mentioned the A-08S puts out 2 watts and the A-011 4 watts so regardless of what the intended impedance is you're pretty limited to high impedance high sensitivity speakers from the get go. The writeup for the specifically mentions Altecs and Lowthers.
I found an image of the manual for building the A-08S kit here:

That shows the schematic for the amp. All in all it's such a simple design I can't imagine needing much in the way of post sales service. Either way I hope it works out for you and eager to hear what you think of a Yammie amp if you do end up picking one up.
Cheers,
Jon
