I went from Quad 63's to Paragon Jubilee/Jems (a three way four piece set up using Dynaudio drivers) to Tyler Signature Systems (One piece). In my room the latter are all that I could ask for - they are as resolved, more dynamic, and you can actually play them loud(!). They are relatively easy to set up but really benefit from using good set up procedures.
The Quads require a far more exacting set up and room treatment to perform as well. The Tylers produce a highly resolved image, including height, but are not bright. They are easy to drive with tubes (I get the best results with 80 wts of PP power, but I have 30wt and 35wt amps that volume wise can drive you out of the room. The Tylers bass goes down into the 20's and I think they benefit from more 'iron' than the little amps have. I recently got the Quads out just for fun - I'd never go back for any reason!
FWIW.
