All good about sound quality , but very bad Windows driver. When you open the software mixer, for example if you want to mute the master, you have to click on mute, a few times on and off to really mute. Also when you record (I'm using Sound Forge), The levels don't match. If I set the levels on Sound Forge to minus 3dB when is recording, after that, the wave is on 0dB, when it's been recorded. So the monitoring and playing levels, don't match at all. Seems that they don't bother to make a new driver for this device. Also I have big problems with latency on ASIO. Otherwise the sound qiality is very good.
