New Pro - SQ for classical music

[arcam]

What I don't quite understand is why SAM (seems to have) made such a difference in sound quality, making it more analog, less digital. Signal crosstalk that amplified the digital artefacts?

To be more clear. If SAM helps you to get a more analogue sound, perfect. But have in mind the losses or better try the above test (SAM on/off) if there are any for you.

Thanks for the detail post @yabaVR. At the risk of disgressing, shall I say that I flabbergastedly discovered that my D's power socket was connected to a Devolo powerline adapter, remnant of a previous setup ? I immediately unplugged the Devolo and... suddenly the sound had become a little more precise.

I now need to try with SAM off.

But, where this post is not off topic, is why SAM would make Milstein's violon suddently less digital, especially since there is little bass.
