OK I am new here and I have few problems: just got my NAD T753 (Linn Index in the front, Linn Afekt sub, Linn Unik center, Denon surround sound) - I know not a perfect setup, but I am in the process of upgrading. 1. Why do we need to buy expensive "full range speakers" when we are going to set the subwoofer to take care of all of the frequency below 60/80 Hz? This is not making sense to me... any help please? I believe a good sub with cheap speakers will do the job as well. What am I doing wrong? 2. The NAD T753 does have the hush noise and it is noticeable... I have also an old (10+ years) NAD 302 integrated amplifier and the sound is much better compared to the T753. Is this the end of the NAD era?
