Firstly although it says this is 150ohms I was hoping it could drive the 650s. It can't it results in the 650 having a bloated bass with mid and treble collapsing. But its not spec'ed to run those so I plugged in the HD599 which sound amazing with this amp
Upon opening the box I was shocked and surprised about the size of the amp. Its really diddy - in a good way. The jog wheel for volume is rock solid and the software free interface is very well done. Everything is touch sensitive and when not using it goes dim only to light up again when your hand gets near to the unit. The plastics used are high quality and the product definitely has a premium feel unlike Mixamp or Creative G5 which feel cheap in comparison.
So once plugged in you need to change the playback in windows to "speakers GSX audio" even if using headphones. You can tweak the sound but i run it with everything off bar 7.1.
Testing on BF1 I can safely say this is by far the best positioning audio I've ever heard. Not only that but its incredibly immersive. You can actually hear/feel the direction of the wind. Its almost too much to take in at first. I've been around the block when it comes to simulated surround below is a list of what I've used before
Creative XFI
Razer Surround Software
Mixamp
Creative G5
Sound blaster z
Sound blaster ZXR
Asus Xonar
And probably a couple of others I forgot due to age
It blows all those out of the water. When I got the G5 recently I was really unimpressed with the direction of the audio cues. Creative seemed to have tweaked what use to be decent and made it far worse. What's great about the GSX1000 is that its better then Creative ever were at their best.
Now I have a soft spot for the original Mixamp. At the time it was a decent product but DolbyHeadphone while having a roomy presentation always had a weird echo. This has none of that. Its clean, precise and extremely accurate. Its like a Mixamp for grown ups
Its a seriously well designed and thought out product.
