It's just an attempt to "improve" on the 1955 mono sound. (Remember the "Electronically reprocessed for stereo" version?)
But if I'm in the same room as people who think the 1955 mono sound is a roadblock to their enjoyment, I'll move to another room.
I've heard the Zenph disc. The "re-performance" (who made up THAT word?) didn't creep me out. I'd be interested in hearing Zenph take on, say, Schnabel in Op. 111 or the Schubert D. 960.
