MHZS 88E comparisons?

I've cruised this board and there are a few write ups about the MHZS cdp's, not to mention the infamous Lampizator page. I just purchased this unit for $650 (+ $50 shipping) as a dealer demo. I've got the common problem -- no idea how it compares to other comparable models/price range. It is unmodded, and would love as an aside any links or upgrade companies that can make them. I have virtually no experience with a solder or iron or electronic internals so would prefer to send it out rather then use it as a guinea pig.

Anybody have any direct comparisons and your thoughts?

thanks so much
