Review: I got this DAC headphone amp to drive my high impedance Sennheiser HD600 (300 ohms) and vintage HD414 (2000 ohms) headphones. These are audiophile phones and demand more from amps than typical device headphone jacks offer. I like this device. It's not too big, the most used controls are up front and clearly marked. There's a handy green signal LED that lights to let me know when my iMac is driving the headphone amp via USB. One issue I find a bit annoying is that the volume changes in overly large dB steps when I change it from the macOS level control. I don't know if this is a Mac/USB issue or if it's internal to the FX-Audio device. The volume changes smoothly in small dB increments from the front mounted volume knob.
Review: I connected it to my old Luxman CD player and Linsoul XDUOO MT-602 6J1 Tube Transistor Headphone Amplifier and it worked great.

## Questions & Answers

**Q: Is there any line noise or pooping sound when taking in optical audio output from a computer? Any popping when music stops playing?**
A: I’ve never had any line noise or popping using optical. That is via a TV not computer but can’t imagine it would be different. The only popping I’ve ever had was if the power was pulled from the unit and then plugged back in while the volume was up but you shouldn’t ever need to unplug it, it doesn’t run hot or draw power when the switch is off.

**Q: Want to connect samsung qled tv to amplifier with passive speakers using optical cable. will this product be suitable?**
A: No. This is a headphone amplifier and signal converter, not a speaker amplifier. You can connect the TV to this via optical, and then use the line outs on the back (red/white RCA) to input to a speaker amplifier, which would then power your speakers via speaker wire, but you will need a speaker amplifier either way. That is how the TV at my desk is hooked up, using a SMSL SA-50 for the speakers. 

If you don’t need a headphone amp, then I would recommend something like the Micca OriGain AD250 (make sure it is the AD, not A). That is a speaker amp with an optical input. But that would only be for a desk set up, where you can reach the volume knob. In a living room, one of the SMSL speaker amps with a remote would be best.

**Q: Does this DAC have native volume control when paired with a Mac? I would like to control volume from the keyboard**
A: No it has its own volume control.

**Q: I have a pair if beyerdynamic dt900! will this amp improve sound quilty and volume? using headphone for playing while drumming.**
A: It will depend the impedance of the headphone itself, because of the fact that the amp is relatively low power, but I can’t say if it will be an improvement if I don’t know what you are comparing it to. But compared to a phone or a laptop, it is a significant improvement
