Hi all, very interesting amp and the street price looks very reasonable vs the pha-3 and ilk. Do you think this has enough juice to run big cans? I have the following, Fisher audio fa-003w (300ohm), hifiman he 400, incoming fostex th-x00.
And am I correct in reading from the earlier posts that it is not possible to use the USB in whilst mains powered? (presumably because the USB is the power in?)
This isn't gonna take long. Sony PHA-3 is a winner, by 25%.
With full charge PHA-3 shelled out close to 6 hours. XPA-700 died some what past 4 hours.
Above said, XPA-700 just needs a single USB cable to carry both audio and power with the option to turn off the charging. battery life is not such a big issue if you are using either unit as a desktop amp or have juice available before the unit dies however I can see the lesser battery life of XPA-700 a issue in some scenarios , example a flight from Tokyo to HK vs Tokyo to Singapore. Would suck to run out of juice when you are carrying all the portable gear with you.
Winner - Sony. Although 6 hours is not that much either.
starblue, in Post 4 you say " Note - all my listening is in pass through mode, no upsampling/enhancement/high gain applied." was that just to comment on sonic impressions or was that the way you tested the battery life as well, this amp really appeals to me but given I would be using it as a portable the battery life seems quite short - I know its busy but still seems quite short.
Thanks in advance,

I used no sonic enhancements coz that's how I like my music. But yes, It's true that the battery life was also judged with all sonic enhancement options turned off. I am really not sure if turning upsampling or other sonic enhancements on or off will have any significant impact on the battery life though.

I have used it with Audeze LCD3, Senn HD800 and Fostex TH900, and although I had to crank up the volume knob quite a bit for the first two, I didn't find the amp lacking power to my liking, can't say for others. Further, I am using these headphones via unbalanced stereo output, balanced might be completely different!

what balanced headphone cables work with Pioneer Xpa-700? I'm thinking on getting the shure SE846 or JVC FX850 and wanted to upgrade to balanced cables.
Not sure what you mean by this. The USB output from your source device (which you use for data transfer) has enough juice to keep the player running, should you choose to keep the charge option on. I don't think you need anything extra or special for charging while listening.
That's true only if the usb source is something like a pc. But when using an android phone as source it won't charge. Hence the powered hub experiment.
