No bloated bass with mine driven by Bryston 7B STs. In fact, if one thing struck me when I got these speakers it was how low and quick the bass is. They did sound unremarkable with my previous amps, especially when I got a tube line stage. Once I teamed the AR line stage with the Bryston 7B STs the sound became quite good to my ears, with the bass being about as good as I ever heard, this side of systems with powered woofers like Vandy Fives or Infinity Prelude MTS. One thing I do find is that the 100v2s require a good volume to come alive, unlike some of the small monitors. The one thing that 100v2s may lack, somewhat, is a degree of airiness found in some other box speakers, that, normally, lack any deep bass. To get both the airiness and deep bass a substantial amount of money (read way way more than the what the Paradigms cost) is required. I know that Vandy fives up here have a suggested retail price of $18,000 CDN, while the Studio 100 V2s are in the neighbourhood of $3,5000 CDN, with a street price, including sales taxes of 15%, leaving you some change from $3000.
Insofar as imaging, set-up and the room itself (proper size and proper acoustics are of paramount importance. BTW speakers in this price range (and well up from it, I might add) are always a compromise.
As another excellent speaker, Canadian made also, with a great price/performance ratio, I would suggest the Energy Veritas which, for what it's worth was well received by TAS. For openness and bass that is nowhere near bloated you should audition the Magneplanar 3.6R, which does requires a powerful amp though.
