auditioned:
- LCD X with ALO RX MK3 B+
- oppo PM1 and oppo HA1
- Sony MDR-Z7 with PHA-3 + Sony custom Kimber cable , and MDR-Z7 with ALO RX MK3 B+

Source:
my Sony Xperia Z1 3.5mm out or usb out with the PHA-3

rough summary:
i still prefer the LCD3 over the LCD X joshuachew comments? lol (if it gets too much we can shift towards the Audeze thread)
the MDR-Z7 is definitely the star for me, threw me off guard as to how close cans typically sound.

heck, E1 - AKG told me it's semi open/closed, however Sony themselves specify it as closed so

i really like the PHA-3, especially as a portal since it can connect usb with my Xperia phone easily.
however the power charging is a total turn off as it drains faster than the puny usb power source could charge it.

in the end i still prefer the stock cable over the kimber ones http://store.sony.com/high-performance-bal...le-Audio-Cables
because:
- comes with the headphone
- black chrome > colorful oddness
- biased preference against silver cables

and ALO audio RX MK3 B+ over the PHA-3 mainly because the PRAT ALO audio amp can provide.
the bass is also definitely much better on the alo than PHA-3

to sum up on the oppo - the bass just doesn't meet my minimum requirement
