Hi funkyoto,
I noticed that you are a new member so you may not have realized that this thread is almost nine years old. ;)
Maybe I can address your question somewhat:
I have a stock 5400es and a ModWright 5400es with all the bells and whistles. The stock 5400es is a fine sounding SACD/CD player. The ModWright is in a completely different league, as well it should be for the additional cost. The ModWright is very un-digital sounding, more dynamically accurate, with a much larger and more real-to-life soundstage, and imparts just the right amount of tube magic to my otherwise solid-state system.
Hope this helps,
Dave
