Tact MKII ?

I've heard it demonstrated at a show and at someone's house. The differences and improvements in both cases were huge (as in, I wouldn't want to listen without it anymore) so I'd think it would probably help your system as well, but I have no idea how it compares to the stuff available today. So it definitely works and certainly worth a try imo, but not sure how user friendly it is.

Are you sure it's labeled as a "MKII"?

Yep, it's labelled as a TCS MK2.

Love the volume control.
