Oh wow. 150mw at 33 ohms is weak stuff. interesting.

How much power do you need? That would drive my Grados to 115dB.

For some, a watt is good to go. Currently using Aune AR5000 and they're super efficient so no issue. Just generally not a stellar headphone amp which is my primary use case.

FWIW I use my Focusrite Scarlett 212 as a headphone amp. It's only 27mW at 33 ohms. I just use it to give me a headphone output for the rare occasions I need one

I am going to use Sennheiser HD 650 300 ohm with Ultra. Is it OK?. What the max impedance can be connected to Ultra headphone outlet? There is no specification anywhere about the Ultra headphone amplifier?

@musig Actually, I didn't. I also wrote "...may be too much..."
I use toslink out to my (four way MiniDSP Flex Eight controlled) main speakers so line out is free. I had the L30 already.
ASR has measured both. The Ultra headphone output is actually at it's best behavior at 300 Ohms load, so maybe it's ok with the 1990s. If it will go loud enough is very individual:
