Example of a piece o’ crap, useless review

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.

Really, Part Time Audiophile as an example of good reviews?  Their stated policy is to NOT publish a bad review.  The puff pieces I've read on their site goes far beyond hagiography and would make even the most shameless fan boys blush.  No measurements at all.

@phoenixengr Point well taken.  Truth be told I haven’t read PTA reviews in a while but used to like his reviews back when he was on his own, so I probably shouldn’t have included them cause I’m not very familiar with their current reviews/writing staff.  Thanks for the redirect.

I agree with the OP that the TAS review lacks substance which is a real shame as there are technical specs in the Pyxi manual as well as several frequency response and noise plots that might put a little more meat on the bones of this review.

  The circuit of the Pyxi was designed by Wyn Palmer and he has published a very erudite white paper about the design as well as his personal philosophy on what makes a good phono stage and the science of psycho-acoustics.  It leans more technical than the review but is still a good read for anyone interested in the subject (the paper is about the Acrux phono stage which has not gone into production but is closely related to the Pyxi in design and execution):

Wyn Palmer White Paper

There are some reviewers I do like , Teajay , Reichert and Robert Harley.

Phoenix, On your comment about my comment that the record brush should not slow down the TT speed, I think when I wrote that I was interpreting the reviewer to mean that he uses a brush that rides the LP on its own "arm", as the LP plays. There are some products like that, some of which claim to remove static charge along the way. I would expect the Eclipse ensemble to overcome that level of constant drag. But I do agree, and do experience, that a record brush can slow down my Phoenix/Roadrunner-powered Lenco, when I momentarily apply pressure to remove dust from an LP surface prior to play. When the brush is removed, the system equilibrates back to set speed within a few revolutions of the platter.
