Hello,
This really depends on what you are going to do with the processor. Do you have a preamp or is this unit going to be a preamp for 2 channel as well as Home theatre. If this is the only preamp you will be utilizing then I would buy the EAD. It tends to sound better in 2 channel mode than the Lexicon. The Lexicon on the other hand has some virtues. I know Lexicon provides updates for their past products. I dunno if EAD provides updates. It really is a toss up.
Hope this helps,
Johnny
