muddy bass can be caused by having your speakers too close to your speakers(feedback). this is a problem with turntables that don't have a suspension system. Some people even put thier turntable in another room.
Fluctuating line voltage can cause speed variations. Check voltage with a voltmeter. Careful,we can't afford to lose any audiophiles. Maybe you have a dealer nearby who wil lend you a power line conditioner.
Before you spend your money be sure you nailed down the tt as your problem.
Lastly, I don't know about clearaudio but VPI offers an elctronic flywheel. Niether turntable has a serious suspension system. A sota cosmso while not perfect at speed is essentially immune to feedback. Good Luck!
