Vinyl heresy-overhang induced distortion is not that important


I have learned and am of the opinion that the quality of the drive unit, the quality of the tonearm, the quality of the cartridge and phono stage and compatibility/setting of all these things (other than setting overhang) and the setting of proper VTF, VTA, SRA, and azimuth are far more important than worrying about how much arc-induced and overhang- induced (the two are related) distortion one has. I learned this the hard way. I will not go into details but please trust me-I am talking about my new ~15K of turntable components for the deck itself and excluding cartridge and phono stage. I have experimented with simply slamming a cartridge all the way forward in the headshell, placing the cartridge mid-way along the headshell slots, and slammed all the way back, each time re-setting VTF, VTA, SRA, and azimuth. I would defy anyone to pick out the differences. I have 30K of tube separates, a Manley Steelhead, and DeVore O/93's. I submit that any differences in distortion due to sub-optimum arcs and deviations from the two null points and where they are located (those peaks in distortion) are masked several times over by distortion imposed by my tubed gear and my loudspeakers. To believe that your electronics and loudspeakers have less distortion than arc-induced distortion is unrealistic. I have heard startling dynamics, soundstaging, and detail with all three set-ups. It is outright fun to listen to and far preferable to my very good digital rig with all three set-ups. 
My point is that getting perfect alignment is often, not always, like putting lipstick on a pig, I think back on my days on owning a VPI Classic and then a VPI Prime and my having Yip of Mint Protractors fashion custom-made protractors for each of these decks and my many hours of sitting all bent over with eye to jewelers loop staring down horizontal twist among parallax channels and getting overhang on the exact spots of two grids and yet never hearing anything close to the level of sound I get now. Same cartridges, same phono stage, only my turntable/arm combination has changed. I kept thinking the answer had to be in perfect alignment when it was clearly everything else but.
Thoughts? I am sure I will get all kinds of flack. But for those that do tell me I am nuts, try my experiment sometime with a top-tier deck/arm combination and report back.

Dear @fsonicsmith : I can't argue against what you are " listening " in your home room/system.

I can comment some issues about your thread and other gentlemans posts:


"""  I submit that any differences in distortion due to sub-optimum arcs and deviations from the two null points and where they are located (those peaks in distortion) are masked several times over by distortion imposed by my tubed gear..... """

Exist several reasons why in an audio system we can't be aware of distortion levels on cartridge/tonearm alignments.

First is that distortion levels is changing at each single LP groove and the difference in between two concecutives grooves is really tiny for any one but a bat could hear it.

Our ears/brain/body can discern on distortion levels when the difference in between those distortion levels is a little higher than tiny tiny differences. We as human beens have limits about of what we can detect and each one of us due to our age and over the time we all have less sensitivity about, the loss of audibility each day goes fall down.

Other reason is the room/system resolution level and its distortion levels where tubes has  distortion levels and resolution truly inferior to solid state good designs: everything the same tubes is way inferior to solid state electronics from inside a  price range. 

You are full of tubes and agree with your statement where in other words you said can't be aware of the cartridge/alignment  distortions levels due that your electronics/speakers high distortion levels: agree with you. The resolution levels in your room/systems impedes to be aware about.
By coincidence lewm owns electronics that has tubes. Btw, I owned the RSA-1 tonearm and never like it and sold.

Other reason is that to be truly aware or detect differences in any kind of room/system evaluations/comparisons we need to have a well proved full self test proccess where at least needs that " always " make the evaluations using the same tracks with different LPs and not even that but to have identified at each LP track the part or parts we use for different kind of evaluation/comparison characteristics. With out that proccess and self training on it we just do not know exactly where we are " seated ".

Other reason of what lewm posted is that we are accustomed to some quality listening levels and when we listen something different  a priori we can say: wow !. But that wow is really a precise better quality sound?


Now, the orthodox cartridge/tonearm alignments what makes is to achieve " more or less " the distortion levels at minimum with and the underhung or what you experienced means almost nothing with out all those I pointed out.

One thing is what we like and other thing is to listen with distortion  ( any kind ) room/system at minimum. Exist a measurable difference in between, many times what we like it is really wrong but who cares: that's what we like it.

I'm in the other side: to stay truer to the recording and what helps to stays nearer to that target is to put room/system distortions at minimum and the cartridge/tonearm traditional alignments is a true way to walk in that road not what you experienced about.

But that is only my target and opinion and for you the validity is only what you like and your experiences, at the end is you who live with and you are satisfied. Good.

Regards and enjoy the MUSIC NOT DISTORTIONS,

Raul, my Beveridge system is mostly solid state. The Manley Steelhead is a hybrid. The Beveridge amplifiers contain active solid state crossovers and the amplification is entirely solid state. Only the output stage uses tubes, a necessity for direct drive of the panels which requires high rail voltages.All the observations I reported regarding cartridge alignment were made using this system. 
Further, you, Raul, used to claim that exact alignment was over-rated. I know you've changed your tune, just as you changed your tune on MM vs MC cartridges.  All of that is OK, but don't pretend to be perfectly consistent in your views.  

For my part, I was asking for trouble with my post, because of the un-scientific nature of my report, NOT because I do or don't use tubes, and I hope not because I am not worthy, as you infer.  This subject is not really a matter of opinion.  The hypothesis that accurate alignment according to one of the popular algorithms is or is not vital to purest reproduction of music from vinyl can be tested.  All we need is a test LP with a single pure test tone encoded over the entirety of one side, lets say 1000 Hz, a very high quality protractor, and a distortion analyzer.  Maybe the test LP would have a mono signal on one side and a stereo signal on the other.  I would be very interested to conduct this experiment.  In fact, I would be willing to buy a distortion analyzer in order to do it (they are readily available on eBay and cost is nominal), but I don't know whether the required test LP exists.  If anyone has info on that subject, please let us know.
Raul;
I try to read your posts. For a man that has submitted almost 9,000 posts, almost all of them long, you surely have had ample time to learn and practice your English skills. You still write the way Yoda talks. Object-subject-verb. By now you should know that we who speak English place our verb before the object and not after. Your object, subject, verb way of speaking must surely be on purpose.
 I am a 59 year old lawyer who writes and reads for a living. I don't have any more patience for trying to decipher your messages. Further, the content I can glean from your sentence structure is often rambling and fails to follow a  linear path of logic. Most of us write in paragraphs even on the internet. Each paragraph contains sentences that build on the former sentence in a linear train of thought. Yoda talk notwithstanding, you write as if each sentence were a card from a poker deck and you threw them all up in the air and then picked them up randomly-what we in the States call 52 Card Pick-up. I apologize in advance for my ad-hominem remarks but until you try half as hard to communicate as you do to argue, I will ignore your responses.
