Check out Brack Electronics. It's downtown just east of Yonge on Front street right in the middle of the downtown core. And they sell everything from Sony to Levinson/Krell/Hafler/whatever else you consider your Holy Grail of H/T. And they have to be some of the most approachable sales people around. If you want to look around, they'll be friendly to you and actually talk to you and let you audition systems (in the absence of other customers...as opposed to certain other dealers who ignore you if you don't come there to buy $100000 worth of equipment).
