Still happy with that amp? I wonder how it pairs with HD800.
It should pair with every cans because:
- it has plenty of power (1.5W/single ended, 4.5W/balanced operation)
- less than 1 Ohms output impedance @1KHOhm
- it doesn't oscillate on capacitive loads
- it has a very low phase shift across audio band
- flat freq. response
- on lowest gain I can use all of my IEMs
I estimate that HD800 will do just fine on both low and mid gain settings. The max gain setting is too high for this headphone, so it will probably be OK with HE5, HE6 from Hifiman.
If you can find a used one at a good price, just try it first with your most sensitive headphone, then with your most hard to dive headphone. Check for background noise and mains hum , but also for "driveability" and audio quality.

I would be interested in reviewing it if someone gets it and loans it to me.
If you are still interested, I have an unmodified HPA-3B I would be happy to loan you.

Actually not a bad price and you can roll opamps. I will consider getting one if it pops up on ebay again.
It is great with burson v5i-d's or opa1656's. I think it's discontinued but it's up there with 789, Jotunheim and LCX for SQ and performance.
