Though I recently sold a pair, I DID keep them for 10 years, so I would HIGHLY recommend getting an ear on some Totem speakers - if you are willing to go used, there are several that would fit your price range including
Model 1
Model 1 Signature (my fav)
Arro
Rainmaker
Rokk
Sttaf and Hawk (likely more expensive, but maybe used at this price point)
They are hand built in Montreal, and designed by their sound, not their specs by Vince B - please, I do not mean to infer that one system of design (measurement vs sound) is superior, but I can vouch for the results - in my experience, these speakers always get out of the way, and let the music out, something that I have always found satisfying.
You don't mention your room size, or music and volume prefs, that could trim the list a little, but all are worth a listen if you can. Alternative Audio in Dundas was a Totem dealer, not sure now. Also Mark in Waterloo at Soundstage is a fantastic dealer, I cannot recommend him enough - good selection of used too...
As for electronics, I think that you are on the right track with the Sim gear, you might find some used in that price range, and all work very well with Totems. I have heard the 4150 with the Model 1's, and that was nice. As for source gear, as far as I know, Classe is it.
Anyone know of another Canuck company that builds sources?
In any case, good luck.
Oh, does DIY count? If so, you can PM me and give a listen to my CSS/DIY single driver DIY speakers, and decide for yourself...
