What would be a good portable Dac/Amp to use with my HD6xx and Sony Xperia 1 V cell phone?
I am new to this hobby. I purchased a HD6XX and plan to use it with my Sony Xperia 1 V cell phone, that has a 3.5mm jack. I was wondering if I needed a portable dac/amp or just a portable amp and if so what would one recommend? Any assistance one could provide, would be greatly appreciated. Kind regards, Haz

Note that my hatred is aimed towards class D and chip amps in general. I'm sure the Grace implementation is much better than the average consumer junk.
Thanks for your post! Unfortunatly, it's deeply misleading on all points.
The amplifier stage in the m9XX is based on the TI THS6012 (spec sheet here http://www.ti.com/lit/ds/symlink/ths6012.pdf ) chipset which uses a Class A-B output stage, but also carries an entirely different set of properties than almost any chipset used in headphone amplifiers available today.
The THS6012 is a current feedback, trans-impedance amplifier. Here's an analysis on the benefits of high-speed (trans-impedance) amplifiers over traditional designs in HiFi applications: http://sound.westhost.com/highspeed.htm
The m9XX also features a dual power supply, giving you the option to power via USB if that's the only option.
If you're interested in learning more about the internals of the m9XX, here's a link to a technical discussion written by Michael Grace specifically for discussion participants like yourself:
