manisandher Posted November 3, 2016 Author Share Posted November 3, 2016 What's the "music server" used in case 2? The music server is a different machine than the Mach II, and sits in my basement. It's based on Chris's CAPS v4 Cortes with an i3-6100T CPU. Not very powerful, but more than enough to run HQPlayer with all DSP off - no filtering, no noise-shaping, no format conversion, etc. (The AR-T Legato USB-to-spdif only accepts 16/44.1, so not much possibility to play around with HQP's features.) The music server was connected to the microRendu and Mach II via ethernet, with a Baaske isolator. Mani.

bibo01 Posted November 3, 2016 Share Posted November 3, 2016 Any upsampling in 2. and 3. ? How curious are you? Link to comment
manisandher Posted November 3, 2016 Author Share Posted November 3, 2016 No, the USB-to-spdif only does 16/44.1. No DSP whatsoever in #2 or #3. Mani.

Enjoy! Mani. Not sure I understand your logic here....take a CD rip, rerecord it as altered by two different playback solutions and then ask others their opinion after all 3 scenarios have been altered by their playback solution. Seems pretty meaningless vs using a digital analyzer to see if any systematic alteration occurred between input CD rip and the recorded Tascam data for options 2 and 3 Regards, Dave Audio system Link to comment
manisandher Posted November 3, 2016 Author Share Posted November 3, 2016 Seems pretty meaningless vs using a digital analyzer to see if any systematic alteration occurred between input CD rip and the recorded Tascam data for options 2 and 3 The system you play these back on should be pretty irrelevant, provided it's of reasonably high resolution - it'll add it's own character to all 3 files equally, but should still allow you to determine which of #2 or #3 sounds closest to #1. And that's all you need to do. But if you have a digital analyzer, be my guest. Mani.

One and a half Posted November 3, 2016 Share Posted November 3, 2016 Item 2 should have less leakage current than #3. This should appear to have clarity over #3. AS Profile Equipment List Say NO to MQA Link to comment
manisandher Posted November 7, 2016 Author Share Posted November 7, 2016 The first set of files I posted were of the digital outputs from the two digital transports - if everything is working perfectly, they should sound identical to the original CD rip. Here are 3 different files (same track) taken from the analogue outputs of a Chord 2Qute DAC... 1. Original file: https://drive.google.com/open?id=0B0PU5LO5jVjfTUdrMGtRRkZuZkk 2. Digital transport A (microRendu or Phasure Mach II): https://drive.google.com/open?id=0B0PU5LO5jVjfQ1JYdk9mVWtEbHM 3. Digital transport B (microRendu or Phasure Mach II): https://drive.google.com/open?id=0B0PU5LO5jVjfMEF3eURHVkU1ZWM Of course, these 3 files should not sound identical to each other. The original file (#1) is fed to a Chord 2Qute DAC. Its analogue output goes through a Pass Labs X1 preamp (to convert the Chord's SE output to balanced), then through a Prism AD124 ADC (balanced input only) and finally to a Tascam's spdif input. Nevertheless, it should be possible to determine which digital transport, the mircroRendu or the Mach II, is the most accurate. So, which file, #2 or #3, sounds closest to #1? I'll disclose which is which later... Mani.

manisandher Posted November 8, 2016 Author Share Posted November 8, 2016 In case anyone's interested... 2. Digital transport A (download file #8): HQPlayer (no DSP) on music server -> microRendu/LPS-1 -> Chord 2Qute -> Pass Labs X1 -> Prism AD124 -> Tascam DA-3000 spdif input 3. Digital transport B (download file #9): XXHighEnd (no DSP) on Phasure Mach II -> Chord 2Qute -> Pass Labs X1 -> Prism AD124 -> Tascam DA-3000 spdif input FWIW, to my ears, file #8 has a similar flavour to download file #2, and file #9 has a similar flavour to download file #3. On a final note, I'd just like to say that I think the Chord 2Qute is a phenomenal DAC for the money, as proven by how closely it can reproduce the original file. Mani.
