High End SS Preamplifier Ayre, EMM Labs, ML, or Pass

Ayre has always had a slight dryness to me. I owned the K1-xe, and auditioned the KXR. I owned an all Ayre system at the time. I ended up going tubes with a BAT REX preamp.
Fast forward....around 3 years ago listened to an Audionet PRE G2, bought it and entire Audionet system. The best preamp I've owned or heard. Check the reviews.

I concur, go with an excellent tube preamp. I have tried several of the preamps you mention but no SS preamp can equal 
say, an Allnic or ARC preamp. The BAT is also a good choice. 
Be careful, the types of tubes used have a HUGE impact on sound quality.

You have owned some incredible gear!  Which factor(s) switched your B.A.T. REX to the Audionet PRE G2 ?  Happy Listening!

Mark Levinson is very fine gear indeed. However, D'Agostino,  is the next league of evolution.  Happy Listening!

not so sure about the dag comment. i used the 523 with a dag s250 and never thought there might be an inequity. ended up w a luxman duo and haven’t looked back but i think the ml is built to an extraordinary level. i had my doubts when i purchased it(523) but they quickly evaporated.
from a purely aesthetic standpoint the ml and luxman are equal to the dag in build quality. just put your hands on them. one quick note. i also have an ARC ref amp and the sheet metal case should be embarrassing to ARC not to mention the cost of the guts. However it sounds good. 
Too long winded. my apologies.
