Moon Nova or Eclipse?

I recently purchased a new pair of Legacy Focus speakers that I run with a Moon I5, AQ Diamondback IC, and AQ Mammoth speaker cables. I'm in love so far, but my need for a new source was laid bare almost immediately. My initial plan was a Nova and then a W3 or W5 amp when money allows. My local dealer has only the Eclipse on display, and told me the Nova was a waste of time. The Eclipse does sound wonderful, but I left confused since I have read many positive reviews on the Nova. Has anyone AB'd the two and found the Nova to be that bad? I'm wondering because I can get the Nova and W3 for a little more than the Eclipse.
Also, is it a horrible idea to biamp with amps of different power outputs? I'm wondering if the I5 on top and a W3 on the bottom makes sense. Thanks.
Golden ears- with all due respect, every other high-end mfr I have dealt with have always made the time for a key question or two- in fact, many of them actually believe that great customer service will make a happy customer- not a novel concept. Ed from Theta is great- when I had some key techie questions about my Dreadnaught amp, he even got the designer (David Reich) on the phone! Also, Israel Blume at Coincident is supremely knowledgable and answers the phone personally.

The two examples above are just a small example of the great customer service I have found from many of the high-end mfr's, and I purposely gave one example from a large company, and one small, both of which have excellent customer service. Sim Audio could take a page out of that book. I'm still waiting to hear back from Costa, and if I don't hear back, that tells me something.

Too bad, 'cause once you actually DO get him on the phone, he can be helpful. BTW, I am in sales myself (database/IT info), and trust me, if I even get a whiff of a potential prospect with interest in my company's services, I am all over it like white on rice...
I have sent Costa questions 3 times and have recieved prompt replies every time. I wonder if he is inclined to not judge their products himself but to let the consumer decide? For what it's worth, the Stargate Aurora combo was reviewed in Home Theater last month I believe.
Okay Sutts. It's nice to know that some are responsive. However, the question you're asking is: (quote)

"All I want to know is how good the new Stargate processor is compared to the Attraction I used to own."

That is something that a dealer should be able to answer for you. If you're looking for an objective opinion, you probably won't get it from the manufacturer. What do you expect to hear? They'll give you the company line. The dealer may even do that, because he's selling them also, but at least he is selling other things.
You MAY get an objective opinion on Audiogon, but the only real way to find out which is better is to listen for yourself.
Agree with Jlamb about "waste of time", dealer really loves money :) My dealer told me that Nova is generally the same circuitry as in Eclipse, but not balanced, and with internal power supply (ok, ok, plastic tray). I run i-5 with Nova about two month... Amazing sound, neutral and crystal clear. Tried Marantz and Linn Genki before - Nova is incomparable better IMHO.
BTW, when I have a question to Costa, usually I have the reply the same day.
Golden Ears- point well taken. Well, all is not lost- Costa finally DID get back to me. The answer was as I suspected- the Attraction is still the sonic champ (superior dacs, etc.), but newer Stargate has more options...
