Many of the people here have experienced all three of these systems, myself included except the Bose... ......price wise they vary from low to high also which is neither here or there.
Sound wise is a personal preference mixed bag regardless of the price ..........
I personally find the Bose compact a very interesting package for a small system for ease of use...I'm not yet convinced on the sound until I put it thru MY torture test very soon using my S900 & vocals. If it passes I might pick one up for the heck of it to use at my small gigs for sure we'll see. What do YOU think between the three mentioned, would love to hear from people that actually have & use any of these units.
