it's a great bag for sure!
this is a quote from Mike in the PB2 thread to me
Seriously! Check it out!
You've got the the maximum permissible 16-Volts supplied to the iBasso PB2 from an inline voltage regulator that allows the 5-cell, external LiPo pack to discharge from 21V when fully charged, to 16V - all the while pushing the amp at its maximum performance (with a constant 16V).
Not only do you have performance that's begins better than possible with the fully charged 12.6V internal battery, it ends at the same voltage where it started - 16V!
Yeah boyeeee!

Maximum possible power, all the time, while portable! Add to this the qusp and SpudHarris recommended combo of LME49990s and HA5002s, and you've got a really nice portable amp.
But it gets better. The Sony PCM-M10 Line Out plays up to 96kHz/24-bit files with gap-less playback, through Sony's proprietary delta-sigma DAC that a couple of Head-Fi members (other than myself) have judged to be in the same league as the HM-801 or HRT Music Streamer II (with less warmth). And you are surely one of very few Sony PCM-M10 owners who knows how to adapt a 64GB microsSDXC card for use in the PCM-M10 (vs. the 32GB limit of the microSDHC cards).
Toss an iBasso DB2 in there for ready use with desktop sources and you are definitely ready to leave the temple! 
It's one of my favorite iPods.
iPod (Original, FireWire port instead of the stupid 30 pin)
iPod (Dock Connector, with the cool button row)
iPod Mini (1st gen)
iPod Shuffle (1st gen)
Nano (2nd gen)
Those are my favorites. Based on design, usability and sound.
Amazing!
They're on the list to buy very soon. Within the next few weeks, me thinks.
LPs are still readily available so that'll be the option. Couldn't pass up this one. The vinyl is my favorite color. :D
2nd & 3rd Gen Nano's here, great little players!
I have a Sony head unit in the car that when you drop the face down, a tray slides out for an iPod. When you close the face the iPod goes inside the head unit with all controls from the front panel or via remote. 
That is where the 3rd gen usually lives with new audio books on it for the daily drive.
I'm curious how you guys with external amps pocket these things? Or where do you keep the rig as you're walking around?
