I may have been a bit harsh, I admit, however I stand with my opinion: the one who says there is no difference between linear and 128 kbps MP3 has no ears and has nothing to do in the music industry

That in itself is no reason to ban the guy. His calling you names might be but you started that yourself imo and afaik others with similar attitudes have received warning first. I think he should receive the same courtesy.
Regarding the sound quality, don't forget that the internal and SRX sounds are indeed compressed and no one knows how. If I'd have to guess I'd say it's probably something similar to RDAC.
Speaking about RDAC, which is a patented compression technology by Roland, a guy over at VS-Planet actually reverse-engineered the algorithm (without consulting the patent application) and built an RDAC->WAV converter program which a lot of V-Studio users now use to export their material from the 2480 to a PC. Roland knows about this and so far have done absolutely nothing to stop it. As in the case of Akai, they seem to be looking the other way (without of course officially admitting such).
Anyway, RDAC is a lossy compression algorithm and depending on the version it sacrifices fidelity, just like MP3. Unlike MP3 it doesn't work in the frequency domain and is not based on psycho-acoustics but it is still lossy.
The point I'm trying to make is that it might very well be possible to decompile the OS to alllow modifications to it. If I were still a student with plenty of time on my hands I might have looked into it myself.
I do have serious doubts about this INOVATIONFANTOMX guy but Art, I think it would show real grace on your part if you would let him back in. Give him the chance to prove that he is either for real or a fraud.
