The M2Tech HiFace is $195.00 on the Amazon US site.
There are several reviews on the Amazon site.
Keep in mind it is designed mainly for use with a home sound system, or with a computer as source....not as a portable device. Although its manual does state it recommends mid to high impedance headphones of 32ohms or more.
Value in this case is dependent on which function one chooses.
Computer or home system then yes.
Headphones 32ohms plus then yes.
Portable device with CCK etc and IEMs then no.
Although I tested it with the ipod touch 6G and also my computer I suspect its intended use is more for a home stereo system.
Its sound is clear, has great detail and clarity and playbacks music fairly accurately. I did notice bass and mids seemed to be recessed. Soundstage was narrow, there was also more height than width.
Some might describe it as neutral but that wasn`t my experience as a portable unit.
Whilst I could get the volume to output at acceptable levels I found I was maxing it out on both the ipod touch and my macbook pro which isn`t the best use of their internal amps. Straight out of the ipod touch headphone out I can listen at around 50% with the Campfire Andromeda, with the M2Tech HiFace DAC I had it at 95+.
The M2Tech Hiface DAC also has plenty of competition out there with other small sized dacs and dac/amps on the market such as the Cozoy Aegis and the Audioquest Dragonfly (Black and red).
The M2Tech HiFace DAC is recommended for headphones over 32ohms and using a computer or home system and not as a portable unit.
To achieve maximum satisfaction this would be better used in a chain of a home system rather than with headphones.
`While the hiFace DAC output is purposely designed to give its best with amplifiers’ and preamplifiers’ line level inputs, it may also be used to drive medium- and high-impedance headphones: try it with iPhone’s in-ear headphones.`
