On DD & DTS I doubt you will tell any real difference, however when a Good TrueHD is played you get a fair bit of additional detail & it's smoother some how. I doubt you will be blown away by it but equally I don't think you will be dissapointed either. I would not go out & spend a fortune on Leads for it, I have tried some expensive ones from my Arcam Hi-Fi & can hear no differece to this one; http://cgi.ebay.co.uk/6-RCA-PHONO-5...ryZ72406QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
Note both are the same lead just one costs more! but has a better photo lower down, I know it sounds crazy & I guess those who have spent an arm & a leg on leads will flame it But I can assure you it's great & if you decide not at this price you can throw it away!
