I've just started a new thread on CA, comparing a couple of old DACs with a modern DAC: http://www.computeraudiophile.com/f6-dac-digital-analog-conversion/digital-analogue-converter-test-old-school-vs-new-kid-31354/.

I doubt whether the thread would be of much interest to many people here (or to even those over at CA?), but it's something that I've wanted to do for a long time. However, there's something that I've just tried that might be of interest here...

Originally, I used the following chain:

Roon RAAT -> microRendu (LPS-1 PSU) -> Intona -> AR-T Legato -> BNC spdif -> DAC -> Prism AD-124 -> BNC spdif -> Tascam DA-3000 (SD card)

But I thought it'd be interesting to try the Mach II too, so I did:

XXHighEnd 2.07 -> Phasure Mach II -> Intona -> AR-T Legato -> BNC spdif -> Altmann -> Prism AD-124 -> BNC spdif -> Tascam DA-3000 (SD card)

Here are the files for comparison:

Original file: https://drive.google.com/open?id=0B0...0F4SXJRZmZ0Unc

microRendu -> Altmann DAC: https://drive.google.com/open?id=0B0...VFYWkdMTTNka2s (file is 1.5dB down on original, which will need to be accounted for during playback)

Mach II -> Altmann DAC: https://drive.google.com/open?id=0B0PU5LO5jVjfb1ZFc1RNMmR4NjA (file is 3dB down on original, which will need to be accounted for during playback)

I didn't want to say it over at CA, but XX2.07/MachII is miles ahead of Roon/microRendu. But don't take my word for it, take a listen yourself.
