+1, I like the A17 myself with the PHA 3. I would say it comes down to which device has the better amp/DAC section. If it is the PHA 3 then by all means complete it with the A17 as a transport, otherwise you are wasting money on one part of the chain to an extent anyway. I suspect the DAC/amp in the PHA 3 is the better of the two with the ZX2 offering the large screen and ability to run apps, but if you're still keeping a phone, I say use that for apps.
I agreed with you on this. However the ZX2/ZX1 are able to play DSD even though it does convert it to PCM first. The ZX1 is a great and most logical solution, sadly the battery life is not too great when connect digitally. The ZX2 is within 5-10% of the PHA3 single-end output. I really do enjoy the ZX2 the most out of all the portable gears that I have thanks to its all day all night battery life as well as its really refined and sweet sounding headphone out.
I went with the A17/PHA-3 combo myself. I have several AK DAPs for all-in-one use. The A17 seemed like a nice, easy, small transport for the PHA-3 (and saved a lot of money).
Yes the A17 is a great choice for the PHA-3. Sadly it doesn't support DSD. I only wish that the battery on the ZX1 is less of an issue with the PHA-3 b/c the ZX2 is just very pricey for just transport duty.

You raise an interesting point. I have been looking at this PHA 3 and the more I look the more I realize it is more of a desktop/portable headphone/iem amp/dac all in one. Somewhat unique approach from Sony. If you connect the unit to a pc/mac then it is functioning as a mini desktop all in one with balanced out. If you connect it to a dap through analogue then it is only a balanced amp. I don't know of another device designed this way (there might be some). If they had used a more practical connector for the balanced outputs it would be even more interesting. They used the top Sabre dac and the standard xmos usb interface. If there is any failing or compromise here it is the xmos but you can choose from many available outboard usb devices to improve the performance of the xmos if you so choose.
They made this device very flexible and to my way thinking very user definable for it's application. Considering all that at the prevailing street price it is an interesting solution.
The PHA3 doesn't have a phase inverter built in so it will operate only in singled end and not in balanced output. I personally will not get the PHA-3 for its headphone output only as the SE output isn't quite optimal for hard to drive phones. I would recommend getting a Headamp Pico Power or iFi Micro for beefier headphone output. You get the PHA-3 fot its awesome DAC & balanced headphone combination.
