I don't know about others, but I prefer a good 'note' rather than loud 'noise' & listening to a constant loud drone for hours at a time would have me into the muffler shop real quick.

My stock coupe has just done a couple of trips between Sydney & Melbourne & a few stops in between during a 10 day period recently & at 60mph indicated [104kph actual] it was only the wind & tyre noise that hindered my AM radio listening pleasure.

Smooth & quiet is the way to go if you're out touring, .... now let me see, which station had Bing Crosby & Doris Day on it again.
