There is a gain switch on the side (Normal-High). See last photo

 
There was a gain switch in the same place on the PHA-1.  They did appear to move the output selector switch to the side though.  That was located on the end before.

I really want to know whether this PHA-2 would be enough to drive HD650 and HE-500.
 
This PHA-2 will be released on 25th OCT.

I don't know how much HD650 or HE-500 need but the spec on their web say 165 mW at 8Ω. PHA-1 have similar spec and can give about 26 mW at 300Ω.

Okayyyy but DrSheep, what does that mean in real life use? Can you help elaborate. Thanks.

 
It simply means very high resolution files....These folk sell them as do others

Yep, Sony and others are starting to push high res content on all fronts, and that naturally include DSD.

Therefor, PHA-1 should be more than enough to drive the HD650 and HE-500, right?
 
But specs are one thing, and performance is another. Did you use PHA-1 to drive any of those tough headphones?

From what I read, they also provide a conversion adapter to support the USB digital input functions of the PHA-2. (when associated with the next Sony AUDIOPHILE walkman ZX1 (with 128 Gb of storage and support for 24/192 !).
 
Finaly a compact audiofile solution !

Does it also mean that I can use it as a usb dac/amp with computer notebook?

Looking at the picture, it seems that YES

These are compatible with I-devices which do not support DSD. You won't get optimal performance with full sized headphones and the DAPs currently on the market which do support DSD all cater for the headphones/earphones that the PHA-2 would be suited to. It looks good but I'm still wondering, what's the point? The Centrance thing looks more versatile, more powerful and has balanced outputs.

Same thought has been running through my mind, too...

Not finally, another. I walk down the streets of NYC with 24/192 files and 300+ Gb of storage...

2x microSD to SD adapters with 2x 128 GB SD cards plus internal storage for sure.
