I find those Listening Sessions to be mostly worthless. So much of the sound quality has also to do with the room, instruments, type of music, settings on the controls, mics, distances from mics, etc. They don't have any samples using the Avalon pres or Peluso mics, which they said they were going to do quite a while back on other forums. All of these are good choices, so pick one and try it out.
I bought an Avalon AD2022, amazing accuracy, no coloration. I am sure now that at least a dozen other choices would have probably suited me, but I had to get it out of my system.
