I tried searching but couldn't find anything. I realize the HA-1 is a headphone amp, but it seems like it also makes a fantastic standalone DAC/Preamp with the little meters and the way people have raved about the internals in the BDP-105 with which it shares. So I'm left dithering between this, the BDP-105 (because even though I *rarely* listen to spinning things, it's nice to have a decent player around, and it's full component width), and the McIntosh D100 Digital Preamplifier. So my biggest question is whether anyone has done a comparison, or at least heard both of these at one point or another to make a comparison of them as *preamps* mainly. I will not frequently use the headphone amp portion at all. Keep in mind, even a used D100 is probably 6 or 700.00 more than either the HA1 or BDP-105 at full blown retail.
