installation of the sound system in the engine is far more critical to good sound quality than what bits are in the decoder. having a quality speaker with a properly sized back enclosure, placed in a decent sized sound chamber that focuses sound waves out specific openings all contribute to better quality.
case in point:
I installed a Soundtraxx DSX in the fuel tanks of a pair of Weaver FA's. Each had a properly sized back enclosure, but the sound chamber is admittedly too small. Coupled with downward firing speakers, you can imagine the quality was not good. I moved weight into the fuel tanks to make room for the speaker enclosure in the body, opened up the fan grill and exhaust stack up top, but no other openings. Now the sound is far richer and of course louder with upward firing speakers. This is easier in a carbody diesel compared to a hood unit, but a similar install using another DSX in a pair of RS11's yielded very good quality with a basic decoder. Having too many openings for sound to exit is detrimental to sound quality because the sound 'leaks' everywhere.
