Bought this and was really happy with the sound. Then I rebooted, and it lights up and then turns off. Researched all fixes, registry edits, power management and still doesn't automatically turn on with a reboot. Have returned it and same problem.

Amazing little DAC/Amp combo. the 7.1 virtual surround is great and the reverb settings are nice, they really expand the sounds past your headphones and make it look like yours walls are speakers. the 4 basic EQs are decent.

Not much besides one usb cable to connect your device to your computer and of course your headphones/speakers to the amp. set windows playback speakers to 7.1 and you're done. the rest of the settings are on the amp itself.

Hopping for a new GSX with these cons addressed, then am 100% buyer. ... Btn Read More

7.1 sound is awesome, not like any other surround i heard; No drivers needed, plug&play

7.1 only has 16 bit/48000 no 24 bit; Mic quality is bad, tested with Game Zero (Motherboard mic sounds way better)

Audio can often feel like the power-supply of PC peripherals: it is the thing people spend the least money on. However if you take your gaming or media viewing seriously, you are missing out if you do not have a decent sound card and amplifier like the Sennheiser GSX 1000.

Sounds excellent throughout volume range, Great for music, movies and games, Best virtual surround sound unit I have ever tested, Looks stylish; Touch screen is functional and easy to use, Ability to control media and chat volume separately

Not the most powerful of amplifiers; Warm sound may not be to everyone's taste; Pricey

Product looks super sexy. The design is fantastic. Unfortunately... this product needs a 2.0 version. The presets are incredibly overly sensitive to even the slightest motion... I had to set all the presets to the same thing because even simply waving my hand over it would change it a different...

The GSX 1000 proves itself much more than a simple headphone amplifier. It also provides a convenient desktop centre for sound output thanks to its USB power supply and housing, featuring convenient volume control and user-friendly switching between speaker and headphone selections.

The Sennheiser GSX 1000 Audio Amplifier is a beautiful external USB sound card equipped with the best 7.1 virtual surround sound system we've heard so far, and a host of other interesting features primarily aimed towards hardcore gaming.

Exactly what I was looking for. I was tired of the buggy interface of my Asus Strix DLX soundcard so upgraded to this. It's nice not having any drivers as everything is customised via the touchscreen.

I compared getting this vs getting a decent sound card with external MAP… And originally went for the sound card. Ended up getting this GSX1000 on a great special, and its an awesome upgrade on even a good soundcard. Great DAC and AMP qualities.
