My current setup consists of four B&W DM303 for L/R/Surround, one LCR3 for the center and an active subwoofer (Jamo D7 Sub). Now i'm quite happy with these speakers (i'm speaking of the B&Ws, not the sub which is superb), they can play pretty loud and produce a fine sound and are quite possible enough for my small home theater (the half of a 18 square meter room, sitting approximately 2.3 meters close to the speakers) the only thing that bother me is a certain lack of the upper bass, probably in the 80-120Hz region, the so called kick bass, therefore it seems to me that the sound is somewhat thin sounding. It's quite hard for me to explain it to you, because english is not my native tongue, so i hope you got it what i meant. I'm not quite sure if this is because of a to weak amp (i have an Onkyo 595 for now but will replace it in the near future, probably with the NAD T752) or because of the speakers. What should i expect from a front speaker upgrade, let's say to the B&Ws DM602 for L/R and an LCR600 for the center channel? Is the price premium justified or is it overkill and i should go with the smaller models DM601 and LCR60 considering the small room or should i upgrade at all? And what about the receiver, how big would be the difference between my current one and the NAD T752 or should i get the T762 right away (take into account that i listen at reference levels sometimes)? I hope you can give me useful advices on my current situation.
