The difference in Matrix-2 by different external power supplies is very subtle. I compared iFi power x, Uptone lps-1.2, and Keces P3 all set at 9v and I couldn’t tell the difference. A small improvement compared to the internal power (?) but I wouldn’t hear the difference if I wasn’t aware of it. Like you, I am waiting for AirLens.
