I am 27 years old and ventured seriously into acquiring serious stuff 3 years ago. It was hard to get decent stuff in M'sia due to its hi tax and relatively more expensive selling price. For now, I am very happy with the sound. If I were to surpass this standard, I am sure it would cost a hell lot more!
Firstly, great system. Quite hard to get an idea of your listening space from the picture you posted, but I'm sure it sounds fantastic. How are the Proac's for bass? Have you ever considered adding a subwoofer?
