Sibbi, Welcome, I am in agreement with Moon and Craig as your integrated amp should get you well on your way. regarding the Quads, I just listened to them the other day at my dealer, he had both 2805 and the 2905's it is amazing that the fit and finish is much improved now that production has been moved to China ! Both sounded fantastic as their respective midrange rivals that of the Logans but when it comes to bass the Summitt (which falls price wise between the two) is hands down superior. So with that being said the Vantage I think is a bargain compared to the 2805 and besides your Bryston intgrated will do a better job with the Vantage than the Quad 2805 I suspect.
Good Luck !!
