I currently have a loner set of Logitech Z-1's.
When we moved to Ohio, I sold my then current setup of Kenwood amp and JBL speakers, with the intent of building my own. Haven't yet had the time to finish the project. In the mean while, my brother in law let me borrow the Z-1 that he wasn't going to use for the foreseeable future. I'm pretty sure he's ready to take them back anytime.
So there you have it, the A5's would improve my sound, since technically I wouldn't have any.
