Pros: Exceptional materials, DAC reader, 80 mW/channel, perfect sound quality, 2 filters and 3 types of gain.
Cons: A little bit big, nothing else.
I've bought it for 489.90 euros and worth them all, the materials are magnificent (the Fostex is MADE IN JAPAN), DAC reader, 160 mW, 2 filters and 3 types of gain.
I've listened it for about 2 weeks, so I can say that the sound quality of this portable amplifier are absolute perfection (FOR ME), if you are searching of the maximum perfection and of maximum audiophile sound quality, the Fostex is probably not for you, the Fostex costs about 500$, there are other better portable amplifiers for over 1000$, but for 500$ the Fostex beats them all.
Apart the fact that the Fostex is a little bit big, i can't find any defect.
