I just finished reading this whole thread and decided to make an account, so glad to find people who enjoy quality sound on their pc! I started reading as the thought of later purchasing a DVI screen "might" come to be. Although, nothing can beat the quality and color of a good TV.
I have a GTX 670 with HDMI going into a Yamaha RXV373 Amp and then HDMI from the Amp into my Sony 32EX720 TV. The Amp powers JBL SCS200.5 speakers which sound fantastic without blowing the budget. I did have to enable the Audio setting in the nVidia control panel before it worked.
Question: Would anyone know if the Default Format makes a difference in quality? This is found under Speaker Properties - Advanced and reads "Select the sample rate and bit depth when running in shared mode" "24bit, 48000hz" I assume it doesn't matter, I see an option that is ticked that gives applications exclusive control, therefore it isn't "sharing". I only ask so we can understand the best quality possible!
I also want to add, when I turn my system on, I need to first turn on the PC, then AMP, then TV after the AMP has clicked twice. Sometimes it doesn't work and sound goes straight to the TV, I then have to turn the AMP off and on for it to pick up the audio signal. Annoying sometimes but I live with it.
