Picking up the amp this weekend. It's actually going through something I completely don't understand but the modder has my TH-900 and knows that it's tuning the amp specifically for it. My concern is his definition of "appropriately tuned" may be different from mine. But I'll find out this weekend.
P.S. anyone who's familiar with the design of the Zana Deux, please feel free to PM me. I have an almost non-existent knowledge of the technicalities of an amp and need some advice.
