Burn in process with new firmware?

What program was that Ian?  I feel an iPlayer moment coming on.

Back to the original topic, my system does tend to sound a little bit better or worse from one day to next.  Maybe due to cleaner mains, my mental state, choice of music, who knows.

I'm in the same boat. I did think of trying a mains conditioner to see if that might be the issue, but I've been doing a hell of a lot of research these past weeks - trying to find anything scientific that's out there about digital cables, speaker cables, mains, and linear power for digital circuitry - and I might be leaning back to my old beliefs that's it's more up top than anything else.

I'm gonna checkout that Horizon too. I've come across many studies around similar themes.
