Is Direct Drive Really Better?


I've been reading and hearing more and more about the superiority of direct drive because it drives the platter rather than dragging it along by belt. It actually makes some sense if you think about cars. Belt drives rely on momentum from a heavy platter to cruise through tight spots. Direct drive actually powers the platter. Opinions?

I see here a lot of simple prejudice: belt-drivers argue what things "should" sound like and why certain aspects "should not" make any difference, in the absence of having seriously tested and heard the alternatives, if at all. These defend their system simply because they own them and not the alternatives. Direct drivers - like Psychic animal - continue to declare DD the best, in the absence of having heard idler-wheel drives, though they feel free to make use of my findings and reasoning, to defend their own system, which they have invested in. In the absence of having heard the alternatives, like belt-drivers, they prepare to make major investments in their chosen system. Chris Brady continues to casually lump idler-wheel drives with belt-drives in the Inferiority Sweepstakes, again I suspect in the absence of having heard the reality, and he is coincidentally preparing to release a DD.

Theories must be tested empirically to verify the truth of a matter: if experiment contradicts a theory (i.e. proves it wrong), then theory must be abandoned or seriously altered. What I wrote up above: "Then there is your message here - "The best of our efforts will compete with turntables costing many times more, and we have friends that can attest to this fact. In some ways, they sound better, especially in the lower end and in that indefinable “pleasure” factor. I am neither an engineer nor a psychologist so I will not try to explain the “boogie factor” these tables seem to have." The fact that you can hear this, and it is repeatable from Lenco to Lenco despite differences in plinth materials, design and weight, points to something in the Lenco proper which accounts for this: it is superior speed stability, which in its turn underlines lack of same in belt-drives. It is, being audible, an empirical fact, and being audible there is a physical reason for it, no need for psychology beyond the human ear's EXTREME sensitivity to pitch (speed stability). It has speed stability which is superior to that of the belt-drives you have heard or compared it to." What Chris Brady then posted: "I have concluded that speed stability is one of the most important factors in turntable sound quality. For that matter it is also one of the key performance factors in digital audio. It is well known and accepted that digital jitter significantly degrades sound quality. What is remarkable about digital jitter is that such extraordinarily small timing errors could be audible at all. The message here is that our ears are far more sensitive to timing errors than with amplitude errors. With analog the principle and effects of jitter/timing errors are essentially the same. In both cases waveforms are being reconstructed and timing errors create similar distortions. Distortions that for some reason are much more audible than one might expect." Same thing, I have known about this since I frst heard an idler-wheel drive and have been promoting it ever since: i.e. I was confronted by the evidence, which is why I harp on about empirical science and experiment, not on-paper theories, which must bow to empirical realities, and not lead them.

Those who continue to blindly promote their own systems in the absence of experience are cheating themselves of an ear-opening experience, and those who invest in a system in the absence of context may find themselves backing the wrong horse, find themselves in financial difficulties, and with serious egg on their faces. Consider the following scenario: with much foofarah an expensive DD is released on the market, and a DIY Lenco shows up which simply crushes it at an audio show, thus crushing any hope for a financial future. Now you may doubt this, but such demonstrations are coming, and you'd better be prepared. I advise you to listen to the alternatives (making every effort to optimize and not rig the experiment by casually and sloppily setting up one system and perfecting the other) before making any decisions. Now, when I was converted to idler-wheel drive, I already owned two highly-regarded belt-drives, I had no reason to convert (in fact the reverse considering the investment in expensive belt-drives). I went out of my way to purchase and restore a Technics SP10 MKII, one of the best DDs ever made, and compare it to the Lencos. The differences were not small, and I have since heard comparisons several times. I have also tried several other heavy statement DDs. Has anyone here done the same?

From a similar discussion a year ago:

"In a word, the sound is "magical", and because, in two words: "speed stability". I will here plagiarize my own text under my "system": "The idler-wheel-drive Garrard 301 grease-bearing was the 'table used by Sugano in the design of his Koetsus, and the Lencos are far easier to repair and restore, and may in fact sound better (more refined while preserving the traditional idler-wheel strengths of unparalleled attack and bass speed and power), for a variety of reasons. Idler wheel drives in general were originally designed to overcome stylus force drag, as in their day cartridges tracked at 10 grams. As tracking forces diminished, idler-wheel drives became more refined, but retained their resistance to stylus drag. As time went on and VTF dropped to below 2 grams, it was thought stylus drag could be combated by the simple use of mass, and not the brute force of rumbly idler-wheel drives, which were discredited, even though their rumble figures were in fact better than those of the then-rising Linn LP12. If you remember your history, you will remember that CD as well was touted by the majority of the press and the industry as superior to the previous technology, vinyl. The Lencos do not rumble, and they prove that in fact it does take a certain amount of (refined) brute force to counteract the all-too-audible problem of stylus drag, which belt-drives are ill-equipped to combat, their Achilles Heel being their belts and weak motors. This is clearly audible in the attack of a Lenco (or large Garrard), the tremendous bass reach (bottomless) and bass detail of a Lenco (which affects both air and imaging), and of course its perfect timing and speed stability under real-world conditions (actually playing a record)."

Now I do not tout the Lenco and the idler-wheel technology it represents merely because I own one, I also own or have owned both high-end belt-drives (Maplenoll Ariadne, Audiomeca) and direct-drives (Technics SP10 MKII, Sony 2250) and a host of others, and so I have actually bought and owned the various drive systems available out there, at very high levels of performance: and the Lenco beats them all by a wide margin, which you should pause to think about, given the Law of Diminishing Returns (should high-end 'tables be so easily and completely and without sonic price beaten?). I am being very scientific, enlisting the world in a global empirical experiment, to decide the issue of which drive system is in fact better. Now while it is politically correct and nicey-nicey to go around saying there is no superior system and it is a matter of taste because there are always compromises and so forth, I say that's all very well, but is it true? Is no system in fact superior? Participants from around the world have declared the Lenco superior to a host of current high-end belt-drives which they in fact owned, and so like me had no reason to declare inferior. The experiment continues. It's cheap to participate and have fun with it! Cost of entry is minimal, give it a try!"

And before you proceed to crucify me, remember my messsage is simple: I do not blindly claim the Lenco is the best, I challenge the world to hear one for themselves and let their ears decide, I put my money where my mouth is, and I make gargantuan efforts to help people in the execution of the experiment so they can decide for themselves. My message is simply : try it first, and THEN decide. This is the heart of empirical science, the search for truth. Or you can continue to argue the superiority of your systems without actually investigating them.
John, I have not personally argued that belt drive is superior. I would truly love to hear a 3 way shootout between a Lenco, an SP-10, and a Teres, Galibier or similar belt drive. I haven't the time, the will or the money to do so.

I have read posts from many who say the Lenco is the best. I have also read posts from people who have heard Lorricraft Garrards and like the bass, but find them lacking in subtlety and detail in comparison to a Nottingham Hyperspace.

I fully agree that your ears are what matters. You should buy what sounds best to you. What I DO NOT agree with is that you are able to declare the Lenco the best turntable, because you and some others like the sound the best. Does this prove that it has the best speed stability ? Not at all, it proves that you like the sound best.

My experience is that the torture test for speed stability is solo piano, preferably a slow movement, like a Beethoven sonata. Yet whenever people describe the strengths of the Lenco or Garrard the first word is always BASS. That does not correlate with my personal experience where a turntable can produce articulate and deep bass, but have terrible speed stability when it is introduced to solo piano.

So, in summary, there may not be a one-size-fits all best in terms of what sounds the best, because we all have different interpretations. There may be a best in terms of measured performance, but using your ears might not be a good way to come to a conclusion.
I don't purport to know anything about idler wheel drive systems and I would be very open to trying one. My principle hesitations are first that I wouldn't know how to acquire a Lenco and I don't have any mechanical skills whatsoever. Mounting a cartridge is on the outer reaches of my adroitness so the prospect of keeping a mechanically complex drive system operational appears discouraging.
What do you say to people like me?
Jack .. there's a Technics SL-1000 (consumer version) and a couple of SP10 Mk2s on ebay right now, for between $400 (no plinth) to $800 (plinth and arm).

I vote you buy one and report back to us in a month or so :-)
Dear friends: The Macrojack start thread question: " Is Direct Drive Really Better? ", it is an open question that has several different stages. Because of that I think there is no single answer of the question.
If we read all the ones posted here in some ways all of them are right answers.

In my opinion we have, at least, two big stages about: one an objective aproach and the other a subjective one and from here we could have another stages like a: objective/subjective one.

From the objective approach what will be tell us which drive TT design is better are: MEASUREMENTS that could be corroborated in a scientific way. What should be measured?, at least: speed accuracy, speed stability ( refered to time ), signal to noise, rumble and woow&flutter.
From the information that I have the DD designs are the ones where we can find almost all those measurements. In the BD designs we can find little info about and in the IW less info.
So with out those measurements info we can't say for sure which drive TT design is better. I posted that the speed accuracy of the SP 10 ( 0.001% ) beats any BD design because searching info about I find that the Walker is 0.002% and the Commtinum 0.006%, but I can't find any info on: Basis, VPI, Teres, Galibier, Simon Yorke, Clearaudio, Transrotor, Brinckman, etc, etc..
Now, for IW the very little info about is really poor.

I have a lot of respect for Johnnantais and when he told us that the IW drive system has a better speed accuracy/stability he don't have a scientific measurement where all of us can corroborate that. So from an objective approach the Johnnantais opinion ( like mine or other people ) has no value at all and can't tell us which drive system is better.
The same is for the " tonearm/cartridge drag " subject: till today nobody can confirm which drive system ( high mass platter or not ) is really better on this subject. All we have are opinions, that's all.

Btw, from the objective approach I think that it is time that the BD and IW defender take their time and money for to have those objective measurements. Johnnantais this is part of your challenge where you can prove you point of view.

Now, if we take the subjective approach then things could be extremely complicated because any one of us could have a different opinion about. Here there is not only our opinion but in which stage are our opinion corroborated, that is, against what: what we like it or against live music?, in which room, with which tonearm/cartridge, which cables, which phonopreamp, wood/acrylic/metal design, air bearing or not, vacuum hold down record?, which mat, which clamp type, which load impedance, VTF/SRA, which records, which speakers, full range system or not, which, which, which and which?, no ended.

With the info that I have ( objective approach ) I confirm that the DD design is the best one. If any of you want to prove that other drive TT designs are better you have to prove it with those measurements not with an opinion, this opinion belongs to the subjective approach and here any of us could be " right ".

Regards and enjoy the music.
