I have an Asus VivoPC (small factor) PC running JRiver connected to the UD-501 via USB.<br /><br />I also connect to NetFlix through this PC. <br /><br />When I first connected it all up, I tried listening to Anonymoushttps://www.blogger.com/profile/16983309963750400599noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-21129058142068077622013-11-16T18:40:05.968-08:002013-11-16T18:40:05.968-08:00This comment has been removed by the author.Anonymoushttps://www.blogger.com/profile/04399582229858259851noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-16931600038668591242013-10-20T08:25:50.485-07:002013-10-20T08:25:50.485-07:00This comment has been removed by the author.Anonymoushttps://www.blogger.com/profile/01647096945457090879noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-71868225625607196032013-09-17T07:39:40.375-07:002013-09-17T07:39:40.375-07:00I posted the above before I saw the results of you...I posted the above before I saw the results of your measurements. Thanks for the measurements, they are what I expected and at least we have a good reason for hearing a difference.

Whatever is happening, I'm enjoying the results in my desktop system (Teac UD-501 > Slagleformer AVC > Mackie MR5's), somehow richer and less analytical. Even low bit rate MP3's are more enjoyable.

Glad to see you got it working.<br /><br />I'll post up some measurements of what "happens" to the sound soon and would love to get a sense of your thoughts on the process...<br />Archimagohttps://www.blogger.com/profile/08642574001287787545noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-56819371988732662872013-09-11T11:17:19.458-07:002013-09-11T11:17:19.458-07:00Thanks for posting this.

If I use the analogue attenuators on the E-MU, that's going to affect the results already.<br /><br />I bet there's going to be significant differences in the other measurements (not the least of which high frequency noise from the noise shaping).Archimagohttps://www.blogger.com/profile/08642574001287787545noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-16273991069657653992013-09-07T17:48:37.068-07:002013-09-07T17:48:37.068-07:00What has the DMAC Protocol to say about the percei...What has the DMAC Protocol to say about the perceived differences and which one is closer (more true) to the original PCM waveform ?<br /><br />Any differences in THD between the analog out using PCM and converted to DSD ?<br /><br /><br /><br /><br />solderdudehttps://www.blogger.com/profile/00391699689539064581noreply@blogger.com
