good evening, I have a denon avp A1 HD, the version with audyssey XT (not 32). I was thinking of replacing it but I wanted to know if there was an equally good product out there in terms of sound, technical measures. unfortunately there are no reviews on the sinad etc, so for example if I would buy a denon x-3700 using it as a pre, would I have an improvement? or is it not worth it? PS. the new encodings do not interest me, I would like to change it just to have a better product in terms of distortion,sound quality,only for blu ray uses,not in stereo
