Hello guys,
can you share what model you are using and with what headphones?
I'm testing both HD600 / DT880Pro and they are not driven loud enough by my Steinberg UR22MkII.
Thank you

Currently the Schiit Asgard 2 - http://schiit.com/products/asgard-2 - with HD600 and HD800S primarily.

I've also tried their Jotunheim, which also works quite well with the above headphones, but wasn't worth the upgrade cost to me personally.

I typically use high gain on the Asgard 2, and with normal listening don't usually go above around 9 o-clock on the volume knob.


Playing since April 2010.

I bought a pair of AKG K240 headphones. Whatever their impedance, they really are "hard to drive" -- some low-end DP's don't give adequate volume, using them.

When I plug them into my Behringer Xenyx 802 mixer's "Phone" output, they play more than loud enough, without any distortion, with the "Phones" knob about halfway up. (I don't claim "golden ears" capability, and there may be distortion that I'm not hearing.)

The 802 is ridiculously large for a headphone amp, and it requires AC line power. The 502 is smaller, cheaper, and probably shares the same electronics. It would be fine.

I think that, to get enough voltage to drive high-impedance phones, you _will_ need AC line power. If I read the specs correctly, the Steinberg UR22 is powered from its USB connection:

. . . there's just not enough "juice" to drive a good internal headphone amp.

Creative Technology makes portable amps that drive 300 ohm headphones.

a fiio e12 came with my DT880 pros.
I also have a 'mint tin' headphone amp which does the job too.

https://www.jdslabs.com/products/1/cmoybb-v2-03-headphone-amplifier/ cheap decent specs and will drive your headphones without any problems and with plenty of musicality and its portable

The cMoyBB is fully capable of driving headphones of all impedances. High impedance headsets such as Sennheiser HD-650's (300 ohms), Beyerdynamics DT-770's and DT-880's (250 ohm editions), etc. are easily driven by the cMoyBB; an 18-24V power adapter can help to achieve dangerously loud volume levels with such models. Moderate and low impedance headphones such as AKG K-701's, Grado SR-60/80/125/225/325's, Ultimate Ears Super.Fi and Triple.Fi's, and Shure IEM's are also commonly paired with the cMoyBB.
Please browse through the cMoyBB's extensive Reviews and you will likely find comments specific to your headphones.

I use the headphone amp in my Audio Upgrades/Jim Williams modded Soundcraft Delta console. Works great for my lower rated ATH M50Xs. But also did a great job for when I borrowed a pair of Senn HD650s, and the harder to drive HD800s. Very clear Pro sound quality.

A friend just bought the Little Labs Monotor. He hasn't stopped raving about it, said it changed his life - in regard to hearing greater detail in his mixes. He said I can borrow it. I'll report on how it compares to my Delta amp when I can get over to his place and pick it up.

The Rupert Neve receives very high praise too.

Those are the two I would look at personally.

I had a slightly different issue with my Sennheiser HD 598.

It wasn't that the piano (N3) couldn't drive it hard enough, it's that I like to practice while watching videos on my tablet; very often the output from a particular video was low and I couldn't adequately adjust both the piano and tablet to my liking.

Instead of buying a headphone amplifier, I bought a four channel Maxie mixer which not only amplifies the headphone but is a great piece of extra equipment that might come in handy sometime.

So instead of buying a one trick pony, a headphone amplifier, consider buying something that may serve more functions.

Just a thought.

(I think I paid €119 over here but now see it for €99.)
