Upgrades for Black Cube

I read in an AudioReview review of the Lehmann Audio Black Cube that someone was looking at upgrading the OPA2604 to something. The reviewer never did mention what OP amp he was going to try. Has anyone modified the Black Cube and if so what did they do.

PS: I all ready have the PMX power supply, so we can rule this out as an upgrade.

Thanks you for taking the time to answer my questions.
