This is a very nice DAC-AMP at a decent price

The build on the FX seems very solid and it makes for a good headphone amp too

I have a good headphone amp in the Marantz HD Amp1 and the Fx Audio's quality isn't much behind

Amazingly good amp/dac for the price, plus it came with a USB cord!

If you have anything above 150 ohms, I highly recommend this affordable dac/amp.

Also now proper power goes to split AV line out of Monoprice 12 subwoofer, and Alientek D8 amp with ELAC B6 speakers

The Amp really improves the headphones, especially the positional sounds in FPS games.

This is, for the price, the best DAC/Amp you can buy

This is by far the best headphone amp for the price

I use the optic input on it and this is the least expensive DAC/amp that has optical, AC adapter, and high enough output to power my over 200 ohm headphones

You can use this purely as a DAC if you plan on getting a more expensive amp in the future

The amp is even powerful enough to run my AKG 712 Pros well

Barring that one small detail, I highly recommend this DAC/ Amp.
