Hi Bill
I traded in for the 2subs and 4mid/high speaker system.. Yes I was quite nervous because the Jbls are really powerful, however it was never really used to its full potential. As soon as I hooked the HKs up, there was a noticeable difference more to my liking at the same listening level, it really took the Audya5 to the next level. Now with its quick set up, built quality, portability and expandability, I think this will be for keeps.
Downside..expensive. Cheers Bill. Ky
