I recently purchased Audionet Max amps which I love, simply fantastic. I'm curious about the Pre G2. I'm currently using a Purity Audio Silver Statement which I find is a great match but might the matching brand preamp be better?

Also, anyone have any experience or know whether the Pre G2 which, according to Audionet's site was manufactured in 3 variants: The original version manufactured from 1998 – 2005, a second version manufactured from 2005 – 2014 and a third version with the metal remote from 11/14 to present. All look the same except the larger logo on the original version and have the same specs. Anyone know of any differences between designs including sonics?
