Hi guys! Im thinking of buying a pair of Dynaudio confidence 5 speakers.Since i miss abit of attact in my Martin logan vantage. I do like the vantage,but they seems to still have that (you must sit here to get the 3D sound)Use to have the areius i and odysse also. Would it be a downsizeing??? I know the Dynaudios are pretty hard to drive 83-84dB. Help
