Yesterday I dug out the two DVD players from my closet. With one of them, the tray wouldn't open at all. With the other one, it worked for about 6 hours, and then after that, no matter what CD I put into it, it gives the error message "disc cannot be read". But I did listen to CDs for those 6 hours by plugging my DVD player directly into the LSR30X. My observations from that are: the sound was much better in comparison to when I use my PC/Modi/LSR30X. From the DVD player, I didn't hear the muffledness, or the haze of static-y-ness (I don't know how to describe that in audiophile terms) that I hear from the PC/Modi. Some of the CDs sounded good to me. However, others of the CDs sounded terrible to me when they were played from the DVD player. I think this might be because of the flat sound that I'm not used to, but I have no way to know for sure. After listening to the CDs, my guess is now that my speakers do not have a hardware problem, but I probably don't like flat sound. In regards to the software sample rate conversion question, no, I'm not certain. But I do know that I've set the "Speaker Properties" Advanced tab in my OS to play 16 bit, 44100 Hz (CD Quality). If there are additional settings that I am supposed to configure in my OS, then I might not have done that because I don't know where & what those settings are. Presuming the issue is within my computer: how do I narrow down/isolate the problem? Is it possible that the problem is the lackluster USB Gen 2 of the Modi and therefore that nothing I change about my computer could fix that problem? Yes, for the most part the Modi is not noticeably better than the onboard...although it is slightly better. I cannot return the speakers or recoup any of the speakers' cost because Massdrop only offers refunds on defective products. But anyway, my Kenwood amp started to emit buzzing sounds a week or two ago (those do not come through the Kenwood's speakers; they come directly from the amp itself), so I will probably have to use the LSR30X since I have no other amp by which to power the Kenwood speakers. That kind of cable is how I connect my onboard to my Kenwood, so I could do that test presuming I don't have to send the Modi back first before I figure out how to make the test work. Could someone please tell me how I'd configure the settings in RMAA so that the test will work?
