Hi, New to this but here goes, I Have a very old pro logic set up and looking to replace the lot, I Have been looking at the Onkyo 705 as part of the replacement + I Plan to buy ACOUSTIC ENERGY AEGO T 5.1 SPEAKER PACKAGE, Do you think that I Need to renew my Cabletalk 3.1 For the front three speakers + Cable talk Theatre Two for the surrounds or go for something else Or do you think they could still do a good job? All the very best, Ian.
