Dear friends: I'm really surprised on almost all your answers on the overall subject.
Why surprised?, if there is true that some of us has no perfect pitch and can't detect " minute/tiny " speed deviations it is true too that other persons are way better in this regard and very sensitive about.
But, why that " no perfect pitch " or " I can't hear that minute deviations " or even " I don't care what I can't hear " where all these kind of opiniuons are only excuses to " protect " the TT already owned.
I'm not a designer of TT but if someday I take that road my very first and main target will be: no excuse, " perfect pitch " design: period.
If the customers can or can not detect it is does not matters, if during the recording proccess ( including those " great " R2R units. ) does not existed that " perfect pitch " it does not matters either even if the customers do not cares about IMHO any TT designer must look for that " perfect pitch " even absolute speed.
Dear audiophiles, please don't take it away the TT designers responsability. A TT exist because the LP needs to spin for we can listen and has to spin always at 331/3rpm or 45rpm: period.
We as a customers IMHO have to ask for excellence design level and not where almost everyone belongs: mediocrity/average level like the excuses that we don't have perfect pitch or that the electrical supply at home is non-adequate or that today is alittle " cold ".
How our hobby could improve when we are not asking for " more " for excellence but given reasons for the audio device designers does not cares about or at least does not cares enough about.
Halcro experiences with his Victor DD is not alone but several of us already experienced the same with some one of those DD vintage TT samples: exist a difference a difference that any one could hear.
Of course that if I own one of those BD dinosaur/mammoth we " accept " those minute/tiny speed deviations with no other explanation that " I can't hear " even if the timeline put in evidence the problem in our BD units.
Years ago and before the Timeline was in the market I posted several times that with heavy mass BD TT did not exist speed deviations due to stylus friction. Not easy to detect it but this fact does not means that I ask to TT designers : perfect pitch.
Our analog hobby is maybe the most imperfect reproduction medium where IMHO we have to take care in any single and " simple " stage where the cartridge signal must pass and where always suffer a degradation. As lower degradation on each one of those steps/links the cartridge signal suffer as better will be the sound that comes from our speakers and the higher the music enjoyment.
TT perfect pitch is one of those steps/links that degrade the cartridge signal even if we can't detect it or if " we don't care ".
As Teres pointed out: there is land for improvement about TT speed stability.
In this specific regard the DD experiences on many of us already showed that are a head to the BD ones.
Regards and enjoy the music,
R.

Dear Frogman: We have to take care about. Unfortunately no one of us have control over the recording proccess where happen " terrible " things that " disturb " ( for say the least ) not only what you are pointed out but the " original " essence of the music.
We can't restore what already were degraded on that recording proccess but at least we can take care that that degradation be the lowest one and certainly the overall TT speed subject is vita. As I posted:
+++++++++ A TT exist because the LP needs to spin for we can listen it and has to spin always at 33.1/3rpm or 45rpm : period. " +++++ NO excuses here.

Dear Dougdeacon: ++++ " concluding that idler wheel/rim drive designs are inherently better than BD's would be going too far. We've had such a design in our system, made by Teres, and it was audibly inferior to our carefully worked out BD. Implementation is always critical and individual cases may trump general rules. " +++++
what do you mean with this? that Paul and you listened to two TTs bis a bis with similar tonearm/cartridges at the same sessions/comparisons?
I know both of you and I have no doubt on what you posted it is only for I can understand how that comparison was made.
In the other side, implementation as you said is critical on any audio device design or on tests as the one you mentioned.
Regards and enjoy the music,
R.
