My personal experience with Direct Drive versus Belt Drive


This is my personal , yet limited experience, with a DD versus Belt Drive. This A/B took place in the same system. with literally the same tonearm. I am choosing not to mention brands at this point. I feel by keeping the brand out of the discussion, anyone who contributes to the the thread (myself included), can be a bit more forthcoming. I am not big on audiophile jargon, so I will keep this short and sweet. I started with DD, in a system which I was very familiar with. The room of course, was different. The DD struck me as near perfect. I could hear the starting and stopping on a dime, and the near perfect timing that many have associated with the DD.  It didn't take long at all for me to conclude this was not my cup of tea. It satisfied my brain, but didn't move my heart. Maybe I was used to the imperfect sound of belt drives, and it was indeed that imperfection, that made for an emotional experience. Who knows? (-: Fast forward to the belt drive.... Again, same actual arm. It sounded more analog to me. Decay was much more easy to hear, along with subtle spatial cues. Was it the less than perfect timing, that was allowing me to now hear these things I could not with the DD?  I have no clue! What I was sure about was the emotion of the music had returned.

So you guys just went off on on a history lesson you did not even research.  Take a little time, as I just did, and pull up a Micro Seiko site.  To say they never where a high end company???  Also if you notice they built both high end dd and bd's at the same time.

The sad part is not you got your history off but you went off topic on the guy who brought reality to the thread.

So if you read between the lines maybe you would ask yourself.  Can you make electronics stabilize a motor on lighter platter (speed/noise/etc) as well or better than a massive belt driven platter.

I realize this is not a DIY forum so I should shut up and let you guys have fun writing.  I was just hoping that Has2be would share his real life experiences with the better tables he has own.

Also if you are to lazy to google information  I will give you a couple of clues DDX-1000 , BL-91 should get you rolling.

OP chiming back in here (-: This is interesting stuff, but in the here and now, I'm thinking modern tables. I bet the new Technics is wonderful, but I would prefer more tonearm options. It seems like many here have been through analog battle.... Any thoughts on a table and arm. Could spend 10-12K, but would love to do it for 6-8K including arm. Tonality above all else. I would never want it mistaken for a digital front end.

My context is not one of history so perhaps my wording confused the issue.
Based on my own experience DD from the mid seventies on took flight in sales.
The electronics end in controlling speed and stability had passed all the other
very significant issues that were common and detrimental to all tables not being addressed as commonplace.  
I disagree that Micro was not making well received and better than mid fi DD tables at the time. Many forget the brands made and designed micro that carried another brands name and the design and parts supplied top other brands on some popular and better than average then tables and many never available in our markets . I said  quote
"at a time when everyone was dumping belt to manufacture DD because the electronic end was at a rabid pace of growth and precision and yet , Micro Seiki went back to making high end belt/string drives"

Now to give you context that was missed the first time. The manufacture of tables was drying up by now in view of the 70's output as less were being built now in the 80's . When I referenced about when I got that micro seiki and  I quoted from the manual their belief of not focussing on a particular drive or electronics ,

("the absolute requirements imposed by mechanical strength , precision and mass cannot be replaced on equivalent terms simply by electronics......we must now stand behind belief that there is no need to stick to *audio common sense* which dictated that it is possible to discriminate all the way between part of the mechanisms of the turntable " .......)    that's actually right out of the manual....
it just always struck me as to how important everything else was/is and something that intelligent rarely gets spoken in a manual of all places and it impacted how I looked at approached things ...........

Now at that time Micro was no longer producing DD tables in numbers as before for themselves as a brand or others and many of the others were STILL building all out DD models when Micro was building all out belt/string drives. Pioneer was building the Exclusive P3a , Technics   was building the SP MK3, Nakamichi the Dragon T1000 etc.....my context is most of the higher end in design and tolerance of machining and addressing more ways to protect the signal from outside influences were on DD not the belted tables that as many were mid fi as you claimed DD were in my opinion then, many. I saw it as ballsy to be building what wasn't yet perceived by the expert descriptive sellers in the magazines as the better choice. I am pretty well versed in the history of it and I think the focus of what really was my context is being over examined as we are speaking in a short period when Technics DD tables were selling like crazy and so were the other brands of DD and semi and auto function became more important than sound and I know that from selling them and that's what people focused on who weren't infected with our disease. Belt drives became less popular , less models made
available here, and remember I never said anything of "better", quite the opposite with not much bias. Then in a blink a few years later CD comes out and the electronics paced to grow it.  Some of the bigger brands of the time were focussing on all out DD units now sought after and ransom paid for , yet Micro went the other way with an all out belt/string drive  that cost more than a car. When for the most part outside of the cult linns  and some then , less know Michell and other tables in the mainstream, many I knew , chased the hi end units being dumped for far less than their real value . I never suggested belt was eclipsed by DD in quality , however in sales in many areas those DD tables it seemed everyone had one and us guys that kept a belt through the latter 70's
and early 80's we were a minority. Personally, with all bias aside of drive choice I think high profit margins to produce lower production cost belt drives and the CD dictated the steering of what became more common again and not what the good phrasing sellers in the rags did or said. America is a big population so while undeniably more belted units would sell in that market but saying they outsold all direct drives during that time...not sure I would buy that blindly but different markets can have different trends though......

    

@  Tom,....good question.
First off I think we all have a bias we focus on that draws us one way or the other
that is where our attention draws and peaks , or fades if it isn't there. For me , I seem to unconsciously focus on voice , and the tone and decay of instruments which  my ears seem to allow my brain to interpret listening with a well set and sorted belt drive while listening to recorded music as being closer to what I perceive it to be when just listening to the naturalness of live sounds. That , for me, has a relaxed feel to it, not the sound as in relaxed, but myself relaxed in just listening without effort and not wondering what's going on here, just seems natural to my ears at this stage. A good belt still has good dynamics on the leading edge notes but for some reason the tone/timbre and decay seem more natural to me and how my melon is interpreting what my ears are hearing.
Direct Drives really do have some distinct strengths that
some will be drawn in with the dynamic drive the sound has to it and its difference in bass presentation and sharper change notes. But I think because of my focus of those tones and decay and the voice as well as instruments doing so, and I hope I don't start a flame war , but in the long term it effects me like CD does as being to abrupt and unnatural to me. Some obviously better than others but very few I can listen to for hours on end of all genres of music. That's not a dish on DD , I just am not looking for what DD excels at , and that how I perceive as slightly unnatural or emphasized. Others love it and that's cool if that's your focus and I don't think we all hear things the same way either not just in the extremes from hearing loss but the interpretation the melon makes of all this . I think our tastes in genre of music play into choice to some degree . I have a friend who just stayed mostly rock and his well set up and sorted DD choice, without question excels at Rock. Not saying they are only good for Rock , just my ears think the dynamics and speed the music gets full attention here like it was played.

I'm actually slowly picking away at rebuilding a hammer tone Garrard  301  table with a pretty good shape unit that will get a nice plinth to sit in after the bearing and drive sees some modern tolerances and new materials with a vintage ortofon
arm . I had one years ago , and after doing one up in a plinth for a friend I really wanted to hear that unique sound a good idler has again.

To answer your question, if forced to one table of the three drives.....
likely a thread/belt drive of  mass simply because of how thread/belt
drives as I said do tone and the decay and timbre of voice and instruments
to my ears. Keeping in mind to be fair , this usually requires added cost to have a stable speed that the better belted designs have in tight tolerances of the control and power supply in relation to the motor, but it really is a common need for all
to be stable and not drift, not just accuracy. Still , I have heard some pretty fricken good tables over the years of all 3 drives. First serious Lenco I heard , if someone had of described exactly what I did hear, to me without me  having heard it , I never would of believed it with any seriousness at all..............







In the real world...everything matters.  You can't put the same cartridge on a different turntable and equate the differences to the drive systems.  Even things like what the table is sitting on, the type of material the base  of the turntable is made of, etc...makes an enormous difference.  Discounting all the different resonances, etc, what I hear that I can attribute to drives is that short term pitch accuracy is affected by the elasticity of the belt itself in a belt turntable, and the blurring of the sonic picture in direct drive due to resonances, pitch adjustment in the feedback loupe, etc.  I am using a rim drive which I find is as good as any, and better than most.  Certainly there are various levels of performance in everything.

Well we are on the same page in music reproduction likes.  For me if the tone is not correct or close why bother.  The late Grizmo was the same way.  Your comments about CDs are also on the mark.  When things made of wood sound electronic that should raise a red flag.

Have been building lead loaded aluminum platters 30 to 40 pounds.  The difference between a 15 pound platter is big.  Drive, pitch, and decay.  I was not expecting decay but stability and or mass helped.

I am building string/belt/tape drives because it is the simplest.  Might try rim set up to see how it does.  The other thing which a group over on DIY forum have been building are motor controllers which can do 2 and 3 phase motors.  Got some really big motors in very big pods which are quite good.  Maybe the drive of the others with the great tone to boot.  If I put on Bob Segar silver bullet live I think I am in Detroit.

If I was guessing I would say most people would be better off playing with phono stages, huge differences.  Thanks for your insight.  It is nice to hear from someone who not only played with this high end stuff but also could explain in musical terms what he heard.  

Enjoy the ride
