Graham Slee Era Gold V or ARC PH3 SE

Any comments on the two of these? I just got a Benz Micro Glider H2 and would rather not switch out. Is that a problem with the Graham? Also, with the ARC PH3 SE, so I need to solder to change the gain?? Opinions on these two?

Take a look at the new ARC PH5 no problem with different loads just push a button on the remote, plus a superior phono pre all around.
