One nice thing about the H10 is how much room there is for rolling opamps (even just the fact I can stick my big hands in there without issue). I swapped out the TI 5532s in the back for, well, another set of 5532s. Got some '87 Signetics NE5532AN in there now. Both those and the '82 Philips NE5532s I picked up seem to ever so slightly improve the tone over the TI 5532s, but the Signetics seemed to have better micro-detail and clarity over the Philips. I've read many accounts of people swearing by some of the older 5532 or newer models from various manufacturers.
You may need an extender of sorts, but there's more than enough room that the OPA134s could easily be swapped out for even a discrete opamp. I'm far from an electrical engineer, so I can't speak for the H10's design and how it will handle other types of opamps.
I suppose the fuse could be swapped out too as a cheap experiment, if you believe that makes a difference in sound.
Nice bang for the buck amp if you can score one around $300-350, especially for planars. Even works well with the HD650, though I prefer something like the Valhalla 2 for it ultimately.
I'm curious, though, does anyone else have an H10 that hums a bit if you put your ear up to it? Very subtle...took me a while to notice. Doesn't seem to impact performance.
