Plinius 102 if you like a warmer sound. I have heard the 9200 as well, though the power ratings look good they do not have sufficient drive and control for the C1.
Go for the Pass if you want something more transparent and dynamic, depends on your source and preamp actually, if they are already tilted towards warmth then you might be better off with Pass. I dont have first hand experience with Pass but have discussed with some audiophiles I trust.
