the difference between 16 and 24 bit is hardly audible in a car you need to have a very keen ear to tell any difference at all. Having said that im getting a 710bt as soon as the prices drop a bit. they have every awesome featurekdc-x993 will have the best sound quality, at least compared to the Pioneer. I know because I liked the 700bt and listened to both h/u on the same speakers. 16 bit dac vs. 24 bit dac.
My ears hear the difference quite easily. I do really like Pioneer though, I wanted something different this time around because Pioneer is all I've ever owned. Hopefully the new 2010 Pioneer's bluetooth feature is better than last years.the difference between 16 and 24 bit is hardly audible in a car you need to have a very keen ear to tell any difference at all.
