Don't really understand why more people don't recommend the PS-2 > AD-20 combo, about the same price as the UA-5, no modding, or clusmy battery packs to make, easy, small, stealthable, and about the same quality. I was thinking long and hard about the UA-5 vs. AD-20, and it looks like I am gonna go PS-2 > AD-20 simply because of the stealthing fact. And then if I want to get Lux's or Oktava's, I always can with the PS-2 > AD-20, doesn't everyone agree?
