yep, Audya sound more RAW, in your face!!!!
when you say SD9 is more compressed,
you mean the samples are just smaller in size?
so sounds like a lower bitrate file, to allow for many more samples, sounds, etc
or more compressed meaning used limiters, compressors, FX etc...
Yes ... compressed using Limiters, built in compressors and in general the new and more powerful DSP.
