Steve, maybe you are comparing the Mackie 450 at too low of volume..I am sure the Logitech will not stay with the 450 at a higher volume

I use 20 year old Roland CK100 Keyboard amps. At low volume they do not sound as good, but when I open them up and eq from my Mackie mixer..they come alive...I like them as much as anything I have heard.
BTW, you may also like what you hear from the Logitech because of Stereo and a sub woofer..
Pair up the Mackie with the Roland in stereo and see if you like what you hear.. balance the volumes though..the Mackie is more powerful.
