These sound just a little more resolving and a little less lean than the PHA-1s. And then there's the price hike of $400........... These are ridiculous to get, or at least that's how it seems in Singapore. The PHA-1 costs $599 while the PHA-2 costs $999. This price increase is totally uncalled for and all the rumors that these would retail for $599 are just plain unfounded.... Sony has kinda let me down with this dac/amp. I was actually expecting a huge improvement over the PHA-1. Or maybe I should just look at it thinking that they tried their best to improve on perfection. Whatever it is, I highly do not recommend purchasing it before demoing.
Thanks for posting this. The poor specs can be "heard," apparently.
I'm disappointed in Sony, too.
Their user interfaces, cosmetic design, and quality control are so high, compared to all the other junk we're expected to consume, but I very much wish they would start designing DAPs and portable amps that truly compete with the "audiophile" junk, in terms of power output.
Instead, they're obviously designing this gear for the "masses" - for people who demand convenience over sound quality and versatility (ability to use inefficient headphones).
Take the 5V USB charging of the PHA-2 battery, for example: This is a convenience feature - nothing more - and it automatically excluded the use of a higher voltage battery that would require a regulated PSU for charging from a 120V or 240v AC outlet, which automatically put a ball and chain on the PHA-2's amplifier section, limiting its output to a tiny fraction of the 2000mW into 32 Ohms (that's two watts!) that the Texas Instruments TPA6120A2 amp is capable of delivering with a 15V supply. Instead, Sony supplies the amp with only 3.7V, for an output of 90mW into 32 Ohms.

The PHA-2 has a 500 HP motor strangled by a tiny fuel pump.
Beating the dead horse...
