Bryston Vs Theta

G'day all. I've just purchased a pair of Dynaudio Contour S5.4's (to replace my KEF Ref 3's) as part of an upgrade and looking for a new amp to drive them. Tossing up between a Theta Dreadnaught 2 and a Bryston 6BSST(LCR)/3BSST(rear) combo (price almost the same here) for my system which is used 50:50 HT/music. Customer service at dealers is a major problem here in Hong Kong (they expect you to buy a $6000 piece of equipment without even listening to it!), so the best I've been able to do is hear these amps with Focus Audio speakers (Theta seemed to have bigger soundstage, but Bryston had better bass control). Must say the Bryston Rep here has been extremely helpful, but can't organise a direct comparison. Any comments welcome.
