Wow, the Audio GD amps are ridiculously huge.
I think I prefer having the AMP and DAC seperated. I trust the stand-alone DACs more then integrated ones.
If it were me, I would probably keep either the ODAC or Modi, then sell everything else and get a slightly warm solid state amp in the $300 range.
I'm still a little suspicious of Audio GD stuff because they seem to try and make amps with the longest signal path/most components possible. Plus all the jumper/flavor switches and what not. It all just seems a little snake oily, and it makes my spidey sense tingle.
