I owned the Ref 5SE and had the chance to listen to the Ref 6 at my then local dealer when it came out. I didn't take it home and use it in my system. I did however take home the Ref 10 and l did listen to it for about a week. It's old but still in it's own unique position of being the top model in the ARC line up. It's the separate power supply. That is a huge difference between the Ref 6 and Ref 10! I ended up buying one of two demo units Ref 10 from ARC.
To all ARC Reference 6 Owners.
Just a question to ARC Ref 6 owners. What made you buy the Ref 6 over the Ref 10.
