If you are looking for a 5.1 set, at a much lower budget, try the Pioneer Andrew Jones speakers. They have been getting rave reviews on the net (check out the huge thread at audioholics). People suggest picking the 5.0 and getting a separate sub. Pioneer should go well with Onkyo.
Thank you for your suggestion. But iam some how not inclined much towards pioneer. Regarding budget, if I buy Zensor 7 towers for front + 2 subs + vocal for centre + zensor 1 for rear and surrounds i.e 2 pair to fulfil 7.2 setup & a pair for Atmos...uff its creeping up steep. This maths have put me away from tannoy DCT 6 SE :sad: . Already blew 90K for AVR + stab+ few cables and adapters. And the tannoys cost 40% more than dalis. Still mulling which one to go for. Mind is shouting "Dalis are VFM" :indifferent14: Anyways want to build up step by step. Next step a 3.1 setup.
