I have yet to purchase TT2.0, will probably wait til a stable release, in the meantime I was thinking of changing sound cards to a M-Audio Delta1010, I currently have a Revo 5.1. My reasons for the change are that I use my PC as the processor and connect analog direct to my power amp. As the Revo 5.1 is a consumer level card it outputs at line level only, resulting in lower volumes. Also the -6db on the sub output is annoying to say the least. I've looked into adding a pre-amp but they are way expensive and add another potential sound degradation link in the chain. Plus Delta1010 has the DAC's external to the PC which is nice (not usually noticeable but nice).
What are the downfalls of going this route? I understand that the Delta1010 has only got 96khz/24bit compared to Revo's 192khz/24bit... would that really concern me if I don't use DVD-Audio or SACD? I primarily listen to CD audio (physical and ripped) and watch DVD movies... with the occasional jap fansub thrown in. Are there any driver specific issues that make the Delta1010 not suitable in the same way as the Revo5.1 is for HTPC use?
BTW... has anyone compared the decoding abilities of the TT2.0 nVidia 4 audio decoder vs the Forceware/2.55 nNDVD?
