Hello, I have a Marantz DV6400 DVD/SACD player connected to a Harman/Kardon AVR430 receiver. I use Mordaunt-Short Avant 906 for speakers (both front and rear) plus a MS 905C central and a MS 907W suboofer. I think that CDs do sound great on my system and DVD-A sounds really exceptional (I currently own 5 of them). I am also happy with the DTS CDs I have, so all in all I am very pleased with my system (I wouldn't want to invest more money in this anyway). The only problem I have is with SACDs. I do find the SACD sound quite fake, with high frequencies having a 'dirty' sound. Now I have read quite a few technical articles explaining that SACDs cannot measure up against DVD-A and that high frequecies tend to sound quite bad on SACD, but I wasn't expecting this to be that bad. I do agree that the mid-range is cleaner and more open on SACD than on plain CD, but when it comes to high frequencies I would choose the CD over SACD any day. Has anyone had a similar experience with SACDs? Thanks!
