@mosler666 The Optimus 50 showed up today. I've been listening for a bit and the sound quality is excellent. I also swapped a pair of tubes a few nights ago that were an improvement.
I suspect that both the cable and tubes have improved things. Excellent detail and realism. Punchy bass. Excellent separation of instruments. Not that it sucked before the change, but things are a bit better. I'm digging it.
Maybe I'll swap some I2s cables for comparison at some point, but I can definitely say that the Veritas cable is not a weak link in the chain.
