I think the Logitechs sound better at low to medium volume. More "guts" to the bass. I would take either system to most small to medium jobs. Fortunately for us, there are lots of good options.
I still like my Peavey Escort a lot, but I like to hear the Barbettas so much it may be sacrificed.
Hank The Lurker is a little under the weather, but even as we speak, I know he will soon emerge from his closet to join the fun. Like me, he had severe Synthzone withdrawal when the forum went down.
When I told my wife the forum was back up, she said "Thank God, now you can stop staring at the empty screen."
