Buckingham, My first thought is how can a student afford such a system as I too went to U of W and through the co-op system and the plan back in the '80's was to use gov't grants/loans money to buy stereo & beer. Good on 'ya. Some of the very well reviewed OTL amps you may want to consider include: Berning ZH-270 (buy factory direct), Atma-Sphere M-60 (avail at Alternative Audio in Dundas, ON), Tenor (if you can afford it and avail. at Audio Gallery in TO), and Joule (factory direct). Beware the 4 ohm loads on OTL - they don't always match well. Ralph at Atma-Sphere sells a Z-System transformer that increases the ohm rating and thus doubles the power. Hope that's of some help.
