Well, let's not expect the absolute best when it comes to a player that is primarily audio-oriented.
As a whole, the F880 series looks to be shaping up to be a nice package, stepping between the mainstream and audiophile categories nicely. The F886 will basically be $299 (if it gets sold in the US), and will sport all the same core technologies as the ZX1, with the exception being that the ZX1's power supply is better built and uses film capacitors for the low-pass filter.
From the description, though I can't be sure because I don't read Japanese, the S-Master HX seems to be a PWM variant, doing D/A conversion and amplification all at once (similar in implementation to the Nuforce DDA-100 Power Amplifier). This kind of conversion requires a custom programmable MCU/DSP chip, so that's most likely why Sony refrained from dropping a Burr-Brown, AD, Wolfson, or ESS reference with respect to DAC chips, and refrained from making references to opamps as well. A well-designed low-pass also makes sense when it comes to designing a good PWM amplifier. The DSEE HX seems to be just a 4x SRC.
Anyway, S-Master HX should be a pretty elegant design. I'm a little concerned with how good of a bit-depth (the best delta-sigma DACs can do 20-22 bits) a PWM timer can do D/A conversion, but since this is Sony, I will give them the benefit of the doubt.
Actually, as a TOTL flagship, I think the ZX1 is a little disappointing. If there's one player that should sport a higher-end chipset, it's the ZX1, as it's supposed to be a halo item. But instead, only the audio aspects are tweaked. I guess they blew their budget upgrading the memory. I don't think upgrading the power supply and capacitors costs that much more, and neither with the enclosure.
