That's not exactly my order, Dear Leader. Let me order it again:

- Stylus shape
- Cantilever and cantilever suspension
- Cartridge
- Platter Bearing
- Arm
- Motor (Including PSU)
- Platter Design and Mass
- Suspension
- System Mass
- Tonearm Cable

On my personal opinion, the stylus shape influences more the sound[trackability, frequency response, transient response, distortion] than all the other items. Unless we switch from an MM cartridge to a ceramic cartridge!!

I insist on considering the stylus itself as an item separate of the cartridge's magnetic assembly.

Mmmmm?

You saying a stylus with a wonderful tracking profile is going to drag the information from the grooves when supported by an arm allowing it to trace a less than perfect track?

And the arm of course being on a TT allowing to interact in a non but perfect fashion and adding some vibration in to the act. etc etc

Probably a bit extreme thinking, but it's the way I view the matter. Of course that magical synergy comes in to play and without delving down the wrong road I've deliberately steered away from compatability and compliance etc.

I kind of surrender though and have to go the way of Bastlnut. Finding out for yourself can be a great adventure and one of learning.

Hello Satan,

What i mean is that, having a decent turntable system as a starting point, this component [stylus shape] will affect more the [trackability, transient response, frequency response, distortion] than the arm. Note that I did not say, for example, "rumble".

And yes, i strongly think the stylus and cartridge affect the sound much more than the arm. ASSUMING, of course, that the antiskate is properly calibrated and working, the vertical tracking force too, and the cartridge position has been aligned.

That doesn't mean the arm has nothing to do with the sound, of course.

Yeah, and also blooming expensive and extremely frustrating. If I didn't discover the margin for improvement by changing speakers first, I would have spent a lot of money for a small gain on other very expensive components. Guided by the knowledgeable wisdom of the hi-fi press....lol

the trick is to take a cold, logical approach to it. Think about what an auto racing team does to extract maximum performance.

Most work within class rules. Formula 3 has very different rules to Formula 1. Within those rules, all the cars look essentially the same - there are only incremental differences and these acheive minute performance improvements that add up to success or failure.

And even in failure, they are significantly faster than your car.

Very few of the improvements that win come from huge change - no new engines, tyres, even driver is a guarantee of success. Witness Mr Hamilton's meteoric rise and fall.

Think the same with your hi-fi and you can't go too far wrong. Make small adjustments and dispassionately record the result. Hang on to those that improve performance, discard those that don't. Optimise, don't reinvent.

When you have got the best you can for your chosen class, you may want to move up - Formula 2 or even 1. You then move into a new set of variables and start the process again.

And just like car racing, many many many people start in karts (off hte shelf mid-fi) some move on ot Formula 3 (hi-fi) but only a select few have the skill and ability ot make the most of a Formula 1 car (ultra hi-fi).

Know your limits unless you want to buy a racing team for your own narcissitic pleasures...

A pair of speakers are never going to weave some kind of magic and replace what was lost at source.

While that is true, the fact is that most speakers introduce vastly much more distortion than what is "lost" by a capable source when compared to an excellent source. We're looking at figures like maximum 0.1% distortion of various forms in most electronics, perhaps 1% tops in turntables, and upwards of 10% in speakers.

There's no point tweaking your turntable setup to yield less than 0.5% distortion if your speaker is adding 10% distortion due to stored energy, cone breakup, box coloration, crossover phase and frequency response errors, driver response errors, and so on.

Crappy speakers will sound crappy, no matter what you feed them. I started with working my speakers up. Now I can hear differences at the other end.

If you had to list components of a turntable which had the most influence on sound, which would it be?


In my humble opinion, I believe the motor is the most important in a turntable. I am only focusing on direct-drive turntable this time. Since I don't use belt-drive these days, I will leave that discussion to other audiophiles. I am excluding tonearm and cartridge, just focusing on turntable. As its name suggest, it is a "turn-table" so if the motor is noisy, has bad bearing, unstable speed, inaccurate rpm, then there's really nothing you can do even if the platter is made of exotic material and damped to zero vibration - besides, in a DD table, the platter is part of the motor! Each rotation should be smooth and even at 33.33rpm, no more no less. Anything deviates from that is not quality reproduction. When I say motor in a DD table, I am also including the drive electronics and power supply as a package for quality playback.

In real estate, people talk about "location location location". Well, in turntable I talk about motor motor motor. Just my two pennies.

Motor, arm, cartridge - a chain is only as strong as its weakest link.

I have to agree with the analogy aardvark. Taking it further, and adding in TNT's OP where he says we are starting with a balanced system, when a car is working well, different tires will give the best bang for the buck. The analog is of course the cartridge, if everything else is well balanced, a better sounding transducer will make the greatest difference and is the easiest to upgrade.

Now if we have a problem in the balance of the car, we need major changes in engine or suspension, the team has to tear the car down and rebuilt/redesign. Most of us in the civilian world would just go buy another car, and like your analogy, we would face the same in the turntable. A new arm is feasible for most of us, a new platter, new springs maybe, but much more than that is reserved for hobbyists and DIY'ers. For most of us we would be looking at an entirely new table (car) that is a complete system unto itself. Then the silly argument over what component within the table is most important is moot, each becomes a feature (selling point) of the whole system.

So you have to decide if you're a Formula team using the shell of a table to add in you own choice of motor, bearing, platter, suspension, et al where each choice is mission critical. Are you a consumer buying transportation at the dealership, where the choices are checking off options on the order sheet. Or are you a shade tree mechanic, restoring and rebuilding an old classic with a mix and match of parts. I see most of us here buying late model used and sprucing up the tires and shocks (cartridge and tonearm). Therefore asking what is most important in a turntable is useless unless you ask it in the context of the end user.

This is going to degenerate into quite a complex debate as has been had many times below unless greatly simplified to give some focus.

Many TT's vary in design, and what's important in some doesn't exist in others! Suffice to say the simple route is deck (plinth) motor/platter/spindle, then arm and cart.

My own thinking is that the point is much more high level to be meaningful.

Your EARS dear Sirs are the most important piece of your audio kit. One of mine is damaged so a dare say I'd never nitice the nuances of tweaking that are valid to some of you.

I subscribe to (all things being equakl and you start with a reasonable deck as the assumption is otherwise rubbish in = rubbish out) that the room itself and the loud speakers coupled to that room are the next most significant. Get these right and all else more easily falls into place.

As for amp over source or source over amp, its only fair to say that each has its influence but the amp must deliver enough grunt to work the speakers best and detract as little from the signal from the source to be effective and have "synergy".

As far as the TT goes (and yes, I know the question was originally about the TT and not the other components, but these things need consideration in context), my humble opinion is that the order is Cartridge, Motor/spindle/platter and plinth (equal) and tonearm/wiring (last) based on nothing more than my own experience.

My recent experience on restoring an old Garrard demonstrates to me the huge difference, even with a modest tonearm (SAU2) that a replacement cart (in this case a Shure M75ED replacing a worn M55) and a replacement plinth has made. Its no good having a Rolls Royce of motors/platters etc etc if you sit it in a crappy casing which resonates to every fly buzzing through the room and then lower a knitting needle into the grooves. perhaps an overly simplistic response but I'm happy that for my system, the points above have been the results of many years of patient research, practice and improvement.

I agree with you and I am at fault. To get a crisp and concise answer, you need to ask a crisp and concise question. When I look back at the original question, it is 2 or 3 questions badly rolled into one. Letitroll98's comment below made me realise.

I should have thought better and split the components simply into Arm, Cartridge and Turntable, assuming if you were going to change something, it would one of each in it's entirety. After all, in my analogy I didn't say Transport, DAC, Preamp, Power Amp, Tweeter and Sub, because this would be too open and impractical.

If you assumed a turntables job was to spin at perfect stable speed and be isolated; arm to hold cartridge and sweep; and cartridge to read info - which generally is the most senstitive to imperfection.

I get the impression from answers that the sensitivities of these are quite similar (Assumming balanced starting components), and not so clear cut as the other devices I mentioned. Each has a similar deteriation to negative change, but affect the sound in different ways.

The reason I am becoming fascinated with Vinyl again is appreciation of the mechanical engineering challenges, as well as finding a well tuned set up.

Off topic here for a brief second. My GF is legally deaf in one ear and is the finest judge of audio quality I have ever encountered. She can instantly tell when there have been changes to the system and in what direction they are headed, bad or good. So don't disparage yourself BigE, you may be better than most.

Back on topic, TNT, follow BigE's advice and use your ears to judge. Strangely, this is a much harder task than adding up engineering specs. As alluded to above, being able to hear and validate minor changes in your system is part inherent ability and part learned skill. When you have a balanced system that just sings, and can identify that, you're there. However you are correct in that it's a journey with no clearly defined path or specified destination. It's the traveling that's the fun of it all.
