Looking for a USB Headphone amplifier


I am currently using a Music Fidelity OBH21 amp with a V-DAC to drive AKG 701 headphones. Though this system provides detail, I would like to improve on the ’soundstage’ and add a little more bass.

To this end, I am looking for USB headphone amplifier and also may upgrade from the 701s. Would like to purchase the amp 1st, one that would support a headphone upgrade.

Any recommendations?

If you live in the US, give The Cable Company a call. They have a lot of headphone amps/dacs in your price range. If you take advantage of their demo program, they'll send you a box full of demo units so you can try them all at once. They also sell your Creek, and will be able to make some comparisons for you.
Courant, thanks for your reply. I am familiar with, and had considered, the sprout. However want a stand alone amp.

ZD, great idea, thanks! I should have thought of CC myself. I will give them a call.
Any thought on the quality of the Benchmark DAC-1 as a headphone amp? As compared to my OBH-21?
I bought Oppo HA-2 headphone amp recently and it sounds amazing. It has asynch USB, SPIDIF, DSD an analog in/out.  I use USB.  Sounds better than my Benchmark DAC1.  D/A converter IC is SABRE 32-bit. It has lithium battery and can be used with a phone, but I’m using it as stationary unit only (next to my computer).

Thanks kijanki, I took a look at the Oppo.  I have not made any move as of yet.  I am keeping an eye on the used market.
