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,

Running the 'y' splitter will result in your main speakers being run full range and the sub using its internal crossover for bass only......

Option 2, would appear to be using the sub crossover to limit the frequencies going to the main speakers.

These are stereo inputs, right?

Do you have a speaker level option?

You will have to experiment to hear which method suits you and your room / speakers best.
