Also, "I did notice that a record brush slows everything down considerably, which was a minor annoyance." That ought not to be happening with the Roadrunner/Condor/Eclipse motor system up and running. Something is off.
This is misconception on the part of the reviewer. The Condor/RR corrects for speed drift over time, it cannot adjust for the amount of drag that is applied with a record brush. All belt drive tables will have this phenomenon due to belt creep. Even the most powerful direct drive tables will loose speed synch if enough drag is applied. None of this should happen while the stylus is in the groove.
In fact, one of the techniques that the Condor uses is NOT to apply correction in the presence of "unusual" amounts of drag; if we did, the speed would suddenly shoot up when the record brush is removed and would take longer to come back down to normal. By not applying correction, the speed will slow while the brush is applied but will quickly return to normal as soon as the brush is removed.
