I had MLTL speakers with 604-8K's in them for a couple of years. Just recently I replaced the 8K's with new GPA 604-8H-III's .
The difference in sound quality was quite apparent. So the 804-8K's went to ebay to some lucky person at a good price.
And I'm a very Happy MLTL/GPA 604 owner.
If you ever venture to St Louis contact me for a listen!
