We don't know what the OP didn't like about the sound...but... I had a demo at a local shop with Sim gear hooked up to Vandersteen Quatro speakers, which I was interested in at the time and which are widely known to be very natural sounding speakers. I played some music I know VERY well from a band I had seen live many many times. It did not sound natural at all. I was very surprised how off the timbre was. The guitars sounded like completely different instruments and their voices almost sounded like different people, or at least like there was some reverb or affect added... The system was SO colored and SO far from the real timbres I had come to know so well...
The gear was ALL Sim Audio, From source player through to the amps...
I don't know if this helps anyone or not. But I think I have realized there is lots of gear out there and lots of audiophiles, too, that don't care much about realistic tone and timber OR plain can't hear that aspect of their systems. Maybe some have not heard it right to begin with or haven't seen enough live music?
Maybe it was just the cables. I don't know what they were.
