BADA DC-222 any good starter mods?

Hey all. I've read a handful of forums that relate to the Bada, seems thats all there is, and I know that I can run with a multitude of tubes and I plan on doing so. But my interest is getting peaked by the other mods that I might be able to do to this thing. When it arrives, hopefully later this week.

First, are there any internal DACs I can use to wire up inside the amp? Or maybe rip a nice one from another amp? Internal isn't so necessary. Just an idea. Second, I've seen quite a few CDPs and amps that have had all kinds of resistors and caps and what not changed out. Anyone know of anything resonable that I can do in regards to this type of modification and where/what I should buy? I'm not exactly a beginner with electronics so if you have specific items that would work, go ahead and list them.

I decided to make my second amp a hybrid and since others use it as a baseline for their mods, I figure it should be worthy of whatever I throw at it. And if I kill it in the mean-time, I'll buy something else. :-) Only reason I didn't buy the Peachtree Nova was that I was trying to get closer to the 100 Watt rating of the Monitor Audio GS10s. Thanks!
