I am currently using 2 Chord company 1.3 silver plus leads connecting a Sony BDP 370 blu-ray player, Denon AVR1909 receiver, Philips 40" 9704 TV together & I am considering uprading them to either the supershield or active silver plus leads. Would I benefit from buying the 1.4 versions over the 1.3 versions? I understand 1.4 has audio return but would this mean the receiver/TVhas to be version 1.4 for this to work? Are there any more recommendations available, I have read the reviews & do like the Chord company leads but would consider any make at the sub £100 price range. I do also use this set up for listening to CD, is using HDMI for music the best option or can I connect differently for music listening?
