I agree with Zog - neither of these would be on my list. These are both heavily advertised (and therefore hyped by reviewers for the pubs in which they spend their ad dollars.) And this spills over into Audiogon - because there's a lot of people who will hear what they're told they're going to hear. This "they're better than such and such at 3 times the price" we keep hearing is just hogwash.
"I am looking for speakers with a great soundstage and imaging. I like good dynamics and low base when it is called for." - This describes virtually every modern, high-end full range speaker from the current crop of respectable manufacturers.
So basically, all you have done is narrow your choice down to the two current "darlings".
I'm not getting on your case here, but rather trying to save you a few grand - the fact that you've narrowed down to these two shows that you don't have that great a handle on what you want, because these are two EXTREMELY different sounding speakers.
I have a simple rule - if you can't hear them, don't buy them. It's one I've learned the hard way. If you live somewhere that you can't hear these things, wait until you can travel to a city and set up a weekend of fun and listening sessions.
In this price range, I would also consider buying used, which gets you closer to nirvana and also limits your downside on buying something you haven't heard yet. Think about it - are new vr4jr's better than a pair of Mint used vr4-gen3 se's that you can get for the about same price if you're patient? I don't think so. The Gallo's with sub amp will set you back nearly $4000 with tax and/or shipping - you can get REAL high end used for that!
I'm not going to get into what I would buy, because that's purely a personal preference. But if you must pick one of those 2 - my opinion is that the VR4jr's are both more versatile and musical.
