Hi all, please can somebody tell me the best way to connect my Wharfedale SW150 subwoofer to my NAD 320. The manual recommends 2 ways of doing this: 1/ split the preamp out to the line in via a "Y" splitter with one cable going to the NAD main amp and the other going to the sub line in. 2/ take the preamp line out to the sub line in and then line out from the sub back into the NAD main amp. My question, is a "Y" splitter with 3.5m of cable (solution 1) better than feeding the main amp with 7m of hi fi cable (solution 2)? I know there will be some deterioration in the signal either way. So which gives you the best sound quality? Any help much appreciated, Swen
