«  It changed my sound »

It makes a huge difference in perceived sound. The price is relatively high, but if you want converters that have the look of it is to be expected. The sound is definitely better balanced corrected and more accurate stereo. I had great difficulty in mastering in my studio before, it is set. Coupled with KRK RP10-3, I mean everything! What is nice is that it can serve as both an audio interface or filter after the existing one. The quality is much better when used as an audio interface (a single conversion DA) Only problem, its connection is firewire ... as I drive with Windows, firewire is unstable. On my laptop, I can run both WiFi and Ergo ... misery! 90% of the time, so I use it in another configuration.
