Jonathan, can you get an AMR PH-77 to review too? Please ……
I would say the ARC Ref 2 and AMR PH-77 Reference phono are two major phono stages for the 2009, if not for the decade.
They all have some very useful features and similar pricing too, 7800euro (~US$11000) vs. US$12000.
Parts quality and features wise I think the AMR PH-77 may be slightly better (can’t say anything about the sound yet) , but then AMR does not have the same name recognition nor history as ARC.
