Lexicon GX7

I recently purchased a new in box Lexicon GX7 multi-channel amp and wanting someone with experience with Lexicon to comment.  I will be using a NAD t765 as the pre/pro and  updated mdc cards with am200 and vm200 virtually making it a t785 with fewer watts per channel. I am wondering if these two components will match up well with one another.  I know that this would have been an inquiry I should have made before the purchase but I couldn't pass up the deal.  Any info would be great.
