Stylus-Drag..Fact or Fiction?


Most audiophiles can't seem to believe that a tiny stylus tracking the record groove on a heavy platter could possibly 'slow-down' the rotating speed of a turntable.
I must admit that proving this 'visually' or scientifically has been somewhat difficult until Sutherland brought out the Timeline.
The Timeline sits over the spindle of the rotating disc and flashes a laser signal at precisely the correct timing for either 33.33rpm or 45rpm.
By projecting these 'flashes' onto a nearby wall (with a marker attached)....one can visualise in real-time, whether the platter is 'speed-perfect' (hitting the mark at every revolution), losing speed (moving to the left of the mark) or gaining speed (moving to the right of the mark).

RAVEN BELT-DRIVE TT vs TIMELINE 
Watch here how the laser hits the mark each revolution until the stylus hits the groove and it instantly starts losing speed (moving to the left).
You can track its movement once it leaves the wall by seeing it on the Copperhead Tonearm.
Watch how it then speeds up when the tonearms are removed one by one....and then again, loses speed as the arms are dropped.

RAVEN BELT-DRIVE TT vs TIMELINE
Watch here how the laser is 'spot-on' each revolution with a single stylus in the groove and then loses speed as each additional stylus is added.
Then observe how....with NO styli in the groove.....the speed increases with each revolution (laser moves to the right) until it 'hits' the mark and then continues moving to the right until it has passed the mark.

Here is the 35 year-old Direct Drive Victor TT-81 turntable (with Bi-Directional Servo Control) undergoing the same examination:-

i owned the Rockport Sirius III turntable (subject of the Peter Moncreiff article) for 9 years (2002-2011). no doubt it did overcome stylus drag. then i acquired the Wave Kinetics NVS direct drive tt, which briefly sat next to the Rockport and i heard the same thing (no stylus drag).

but stylus drag is not everything. there is also something called 'steady state speed'. absolute servo corrected speed i think might be not quite as significant as steady state speed. our ears seem to be very sensitive to the speed being steady.

recently i added a Saskia model two idler turntable to my system, which sits along side my direct drive NVS. i've switched cartridges and arms from one to the other these last couple of months. the Saskia is not just another idler. it weighs 250 pounds, has a Pabst 3 phase motor, and very heavy platter. the Saskia has no servo loop for speed. it sets the speed and then maintains it. inertia and the leverage of the idler wheel keep things steady.

as a result there is a solidity and flow that is undeniable. the tonal density must be heard to be believed. zero stylus drag + absolute steady speed. 

i had heard the Saskia at shows back a few years and was always very impressed, although the systems it was in were unfamiliar and different than mine. so i thought i knew what it might do, but it was a stab in the dark.

i just love what i'm hearing so far. every day of listening to the Saskia is a learning experience. i still enjoy my NVS direct drive too. they both have their strengths.

stylus drag is a real issue. but servo correcting speed comes with a price too.....even at the very tip top of the food chain.

The Sonus Gold Blue has great reviews and high recommendations.
A while ago a member was going to sell me one from his stash but then he just fell off the face of the Earth so it never happened.

I still peruse eBay and here etc but never see a complete usable one.

Shame...... 
On the other hand I’m sure that beyond a certain point none of us can readily hear speed imperfections, especially not those quoted for the Monaco 2. I mean I know turntable speed matters, it matters a lot, but this is overkill, isn’t it?

No - definitely not overkill.

The gains from stable accuracy are substantial. it’s all about time - the cartridge provides the amplitude of the musical signal but the time element - the frequency - of music comes from the turntable’s rotation, ideally at 33-1/3 rpm.

It’s not a question of what you hear when speed is off, it’s what you hear when speed is both stable and accurate. Wow and flutter are unmeasureable with the Monaco and a few other advanced direct-drive tables (eg NVS). We’re well beyond old standards.

Any aspect of reproduced music related to time - depth, soundstage, transients, dynamics, tonality, etc. - is better or worse thanks to timing in the creation of the original signal. And no amount of downstream electronic wonderfulness can ’fix’ that signal if the turntable rotation is not accurate. These are not just technical considerations, but tangibly audible results.

Perhaps Technics (orig Sony) claim of eliminating direct drive 'cogging' have finally turned the tide for good this time.

Use of spotless motors does this.  Equally important is the drive system that controls them.

@uberwaltz- Yeah; they were kinda special and now, pretty much unobtainium(popular and rare does that). Had I known then: I woulda/shoulda/coulda had mine retipped and kept it. That’s one of very few components, that I’ve sold and wish I hadn’t. Perhaps: thinking about selling his Sonus, pushed that member, "off the face....."? Still, I’ve had some very nice, high compliance MCs, since. My Soundsmith is no slouch, either. They’ve all helped me to address/minimize stylus drag, at the source(to me: better than Band-Aids).
