I love my little Quad 9Ls;will I like bigger ones?

On a whim I bought a pair of little Quad 9L desktop speakers for my computer and I'm shocked at how much I like them. I am tempted to try a bigger pair up the line for my main system.
The 9Ls on my computer have a balanced sound from top to bottom with no shrillness, grain, or boom; not much deep bass but a pleasant, well-incorporated bass that seems to fit just right. Vocals are beautiful, and the soundstage is small but the relationships between the parts of the music, even in mono from my computer (even youtube),
are evident. This is a stress-free speaker that is very refined but not overly dull or blunted. Most important (to me), nothing seems be unnaturally pushy. With other desktop speakers (with tone controls) I was always turning down the treble to tame the digital glare or brittle upper highs. The 9Ls have not tone controls, and thankfully, none are needed. (I use Cardas Golden Cross ICs).

Are the bigger Quad cone&dome speakers similar, or are the 9Ls just the sweet spot in the line? (I see that the other Quads have mixed comments, but I was wondering if others could comment or confirm what I hear in the 9Ls. Thanks in advance.)
I had the 12Ls...and for a monitor...they have very clean, deep articulated bass...some of the best Ive heard...further up the chain the midrange doesnt possess the 3d realism of some higher end speakers(GMA, VANDY)...and the tweeter can be a bit forward for my tastes...but its still a good to at times very good speaker...one could do alot worse...
Phasecorrect, how are those GMAs?
Quad makes good speakers- not question but the 9l is a completely different design than the 11 and 12l active. Passives are another entirely different animal too.

All sound good but different.
GMA Europas...excellent speaker in terms of audiophile imaging, soundstaging, transparency, etc and truly amazing on vocals...I found them to be a bit bass shy...to be fair this was in a 20 x 20 room...and the bass they did produce was of average quality...a little loose for my tastes... all depends what you listen to...i like reggae, dub, electronica, etc...
