Thats kool. All I know about sound is what the people I know tell me. A bloke I worked with up North had a $20000 setup in his car, and he told me heaps, like the use of sound proofing, speaker placement, interior shape and more????? So if digital is great quality to make it work you will need, amps, speakers and subs, so me thinks your Digital radio setup for your bike will easily cost you over a $10000 so it works, but most likely more???????
+ The earphones which would have to be noise canselling. Hmmmmmmm if your after the good ones like Sennheiser or better me thinks at least another $300. So for around a couple of thou you will have a great Digital radio setup for the bike
I only had a radio on the bike for a change to my Mp3 music
