Never heard of chocolate wine until I read this. So I googled it and I'm not sure I want to know more. "ChocoVine" sounds - wrong, somehow. Like, "GummiAle, anyone?"
That said, I'm enjoying Lindt chocolate with chili pepper at the moment (highly recommended by me) so I shouldn't be so purist, I guess.
So far, I'm very happy with the VP150. I listened to the 160 as well but preferred the 150 in that room and haven't any reason to make a change.
I am thinking about some acoustic treatment. That corner behind the sub is awfully bare and there are times when certain frequencies rather take over. I don"t know how effective MCACC is on low bass.
