Pros: Format support, sound quality, amazing build quality

Cons: Front panel easily scratched, low output power

Excuse my English

 

First off the DAC is 24bit no matter if its on PC/Mac/Linux
it Decodes PCM 192K and DSD 2.8/5.6 MHz

 

Build quality: One of the best on the market. the casing of the unit is 3mm thick aluminum. Components on the circuit board are neatly laid out.

 

Sound Quality: I don't have high end headphones, but Low impedance phones really sounds good (<150 ohm). The sound is balanced.

 

Filters: Fast and Slow roll-off for PCM, Low and High cut for DSD. PCM roll offs are easier to notice for the bass, DSD cut off is just lowering the ampitude as some DSD are recorded over 0db

 

There are also other features:
Optical input and output, can be used as a converter. the output is always on.
RCA output, i also have powered speaker that I use with the HP-A4.

 

Specs from fostex jp website:

 

Output power:

32 ohm load: 100mW

DAC chip: Taxas Instrument PCM1792A
