Hey everyone
I also have been part of the Beta-Testing Team and am very impressed by the product itself and the passion and perfectionism i witnessed from Steven and his whole team during this process. These guys have been renlentless! Continuos and tireless tweaking until the product was there were they wanted it. Congrats!!
As for the product itself, I totally agree with the other Beta testers on this thread: It sounds excellent and the mixes translate very well to the 'outside world'.
To me the main advantage compared to other somewhat similar systems out there, is the fact that this is a specifically and purposefully designed hardware/software HYBRID. This ensures that everything on the listeners side sounds exactly the way it was intended by the programmers - so the emulation of a particular room translates perfectly to your pair of headphones. There are many selling points to this product but for me one of the main advantages over somewhat similar systems by other manufacturers is that it takes out the guesswork/insecurites on the side of the user (are my headphones right for this? Should I use Sonarworks after the emulation? etc.). Although the tech behind it is very complex, for the user it's incredibly simple to use: install the software, plug in the headphones and mix away.
