Now after four week with the NOS1a i want to share my experience with you.
I was very happy with the NOS1 and I could hardly imagine that it could sound better! I'm using speakers with compression drivers for the high and middle frequencies.
The NOS1a is another level: detaills, space, etc. You can read a lot of positive reactions on the forum. I have the impression that I have more Bass. Good for the Piano to have more body. Im listening very often to jazz. But on some cd's the acoustic bass becomes very annoying (Kate Bush-title track Areal. This was with Windows 7. Some cd's sounded complete different. Piano with more space around it. I have read the Win 7 /Win 8 discussions on your forum many times, so i decided to install Win 8 expecting to get a better bass. Windows 8 is a big change. The bass is better, but sometimes still to much/ annoying. The music is more in your face. When i'm talking and playing music, the music irritates me sometimes. Very detailled but i'm missing the space around instruments. Missing 3d space/image and depth. I have tried to change the XXHE parameters, but the influance is minimal. I'm using under clocking and all the usual Win 8 XXHE parameters. I've changed the interlinks but the effects are minimal. I'm thinking to go back to Windows 7 to get a more relaxed, 3d, spatial sound. Any suggestions to improve the sound in Windows 8? (any change to develope an OS for XXHE? )
High regards Johan
