Ok, so let me but all my cards on the table:
I was thinking maybe I made a mistake ordering the classic instead of the normal ONE 2. My thinking to begin with, was that I wasn't ever going to use the sub output and I thought I wasn't going to use the volume control, for more than the initial testing. So I might as well save the $50 for a preamp with the inputs I need.
But now I found out how hard it was to find a good cheap passive preamp. And I was contemplating sending the amp back to be replaced with the ONE 2 with the better "pot" and just buy a simple phono input selector.
But now this one comes up...
The ultimate question is: Which option will give me the best overall sound quality?
Or in other word how much better is the volume "pot" on the ONE 2 than the one Mav if at all.
It'll cost me about the same everything included... (most of my sources are digital).
