First upgrade from Linn Classik?

I've thought about your post some and a few missing data points would make all the difference. What are the dimensions of your listening room? What is your primary musical preference (rock, jazz, folk...)? Do you listen to your music mostly at what most would consider a reasonable level, or do you like to crank it up and rock da house? It's worth mentioning I've never been a Linn fan, but I do own two Classiks and enjoy them. I also own ML Aerius' (not driven by a Classik) but my room and musical tastes may very well be different than yours. The ML's perform well with most music, metal or organ music would require a sub to fill in the lowest notes. ML's also shine when they have plenty of juice, otherwise they tend to sound a bit shallow and lifeless. Without knowing too much about your specifics, if I was to use the Aerius' in a main system in a "typical" room and valued bottom end and slam required by most rock music the Classik probably does come up short. If I wanted to keep the system simple, cost effective, and musical while adding the "balls" you seem to lack in your current set up I'd probably consider using the Linn in a secondary system or selling it, and pick up a Magnum Dynalab 208. If you want to go the way of seperates (CDP, preamp, amps), that's a subject that would take lots of time to cover and end up with plenty of opinions.
