@bjesien I don't think the source or cables are limiting anything,.. the source is PS Audio AirLens (via i2s) into a DirectStream Sr (modified). All analog cables are SilverSmith Fidelium and so are the speaker cables. I've been using this setup for years and extremely happy with it.
If I use my little backup amp, Luxman SQ-N150, the sound is very sweet and you can listen for hours, but it's definitely a bit underpowered (you can hear compression at louder passages even if you keep the volume control moderate).
In the perfect world, I would find something like the SQ-N150 but with the power and (most of the) details of the Pass (and the bass of the Pass).
