Yes, I've been told the Lingo 4 is a significant upgrade.
The Karousel is an amazing upgrade. the noise level has dropped significantly. IMHO, the bearing upgrade is fundamental to the table as it removes a lot of the vibration from the turntable.
The old saying that the notes "come out of the black" is true. The dynamics, micro and macro, are sooo much better that the imaging is far more accurate. The position of instruments/voices is now accurate front/back and left/right. and low level signals are not lost when the music gets loud.
In the meantime, I upgraded my preamp.... got a CJ ET3SE line stage ( keeping my DIY Super Duper Adjustable DIY Clone Pearl 2 solid state ).
Mostly, I'm on a tear to lower the noise floor. Right now I can play Warner Brothers LPs from the 70s ( after vacuum cleaning ) and the noise floor is as low as playing Tidal 24/96 over a Burson. And THAT is awesome.
Gonna start looking for the Lingo 4 in early '24.
