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:-

ok, since we are in a free fall anyway here we go......

back in the day (in spring 2001) i had borrowed Atma-Sphere MA2 Mk (something or other, i’m sure Ralph will jump in to clarify). had them in my system for a couple of weeks, and was about to order a pair. very impressed other than my wife thought they were ugly. then the friend who loaned me the MA2’s called me to tell me about some other tube amps he had, the 75 watt Tenor OTL’s. i went to listen to those and preferred them to the MA2’s. the Tenor was just better to my ears. more fleshed out and natural sounding....with a magical mid range transparency and sparkle, even though it had quite a bit less power. so i went with the Tenors.

three years later, after a number of Tenor OTL explosive events, i had the opportunity to try this new solid state stereo amp, the darTZeel 108. here was a solid state amp that did not sound solid state, it had that breath of life of tubes, but the low noise floor of solid state. i loved it.

i still love it. i’ve had some pretty awesome tube amps in my system to run against the big darts. the big darts are still here. (if i ever stop buying turntables, arms and cartridges i will upgrade my 7 year old 458’s to the new 468.....but not yet).

my reference sound now 18 years later is still that Tenor OTL. and the darts deliver it....and much more.

and you have every right to your opinion on the look of the darTZeels. opinions are free.

a note about Atma-Sphere; no one takes better care of customers than Atma-Sphere, and i love the sound of their amps. and Ralph is a great guy and very helpful on the forums. i just don’t happen to own them. i’ve highly recommended them to many over the years.

basically i’m a tube guy who owns solid state.

much respect for your amp install approach, but a useful discussion of the details of active isolation is too deep for a brief comment. it's a big subject. maybe another day?
@mikelavigne , "basically i’m a tube guy who owns solid state."

That's also true of most of us here, isn't it?

I just wish someone would put out a solid state amp in tube disguise. They say looks aren't everything, but they're certainly something.


That’s also true of most of us here, isn’t it?

i suppose it depends on your definition of ’here’.

on an analog oriented thread like this one, i’d say most have, or prefer, tubes or a tube like presentation. otherwise in general maybe a bit different. just my 2 cents.

i do think that darTZeel solid state does get as close to the positive attributes of tubes as any solid state. and avoids the worst of solid state similarly. even though it's got that red and gold 'ironman' look.
mikelavigne, you ever listen to JC-1's in your system? Maybe just a slightly better value many of us can afford. 
Not a free fall. Interesting. I'm all ears. Active isolation? I thought a concrete foundation was pretty isolated, unless you live in California on the fault line. Tell me it's your wife that liked the look:)
