This has been out of use for some time as I only had surround sound set up for less than a year before I decided to just use 2 channel so it has seen little use. The Martin logan Cinema i is very much like the Earlier Martin Logan Cinema but with an external power supply and an optional adjustable base that I never used and cant find. I have the external power supply and made sure it works and sounds perfectly. I only see one minor mark on top that you can see in one of the pictures. The manual is downloaded. This speaker sounds great and is in cosmetically excellent condition but without the optional base.
