Generally speaking, the EAD has always proven to be a better option for 2-channel sound quality. Lexicon is heavily slanted towards HT/multi-channel steering, and tends to leave 2-channel as its least important function.
The 2-channel pass-thru circuitry on the EAD is very transparent and dynamic. It certainly won't give you the mid-range magic of a tube preamp, but it is a reasonable alternative to a good solid-state preamp if you must use only one device in your situation.
