Hi all, I am not sure if my post will belong here but i will give it a try. I am searching for help on this one for sometime now. I hope I will have a few good responses. I bought the Onkyo TXNR609 because it has a USB input to be able to playback FLAC files. 1. I am disappointed to find that the play back of the ripped FLAC (44.1/16), via USB into Receiver, is not as good as the original CD. 2. My equipment: LG HL-DT-ST DVDRAM GMA-4020B ripping drive, Cambridge Audio 650BD DVD/CD player, Onkyo TXNR609 Receiver (with USB input having 192/24 DACs but only plays up to 96/24 FLAC files via USB). Q1:Which is the weak link in the rip/playback chain? (a) Ripper drive, (b) EHD/USB output to Receiver or (c) receiver? I would personally discount (c). But I do not have enough knowledge to say which of the other two links. The track ripped by EAC gives a confidence 2 and ripped by dBpoweramp gives an accuracy of 2. Does this show I may need something like Plextor 230A or similar for ripping to a high accuracy? Or is there another reason? I need to eliminate the cause before I rip all my CDs. The track used as a test is U2, The Joshua Tree, Where the streets have no name. Any help will be most appreciated. Regards William
