I own a synchrowave and it makes a difference, but whether or not that difference is substantial is hard to say. The sound, particularly with piano, becomes clearer without being lean or edgy.
There are some minor quirks with operating the synchrowave. When it is plugged in, it is on some level "on." On several occasions, I have come home to find the table has turned itself on fully (meaning the table is rotating). I believe this can happen after a momentary power outage. To prevent this, one has to either disconnect the synchrowave, or do what I do, which is to always turn the motor itself off after use.
If you are looking at a older table, an even bigger change in sound is wrought by buying a new belt. The new belts are machined to a higher degree of precision. This is a relatively cheap upgrade that should be done regardless of the condition of an older belt.
