Since you have a ARC preamp and are talking about that kind o money definitely look at the ARC REF 160s. It is magic and the synergy with the other ARC equipment is incredible. I have Sonus Faber Amati Traditional speakers which have the same impedance as yours. As I flipped each piece of equipment to ARC Ref... the synergy just took my system to new levels. I am constantly glued to my system now, it has a sense of rhythm and pace I have only heard with gutless systems before yet with an amazing soundstage, detail and power.
If you are having doubts, read some reviews. There is a reason the REF160 is wining awards everywhere.
