Hi Ked
There is a Wave Kinetics NVS for sale on Audiomarkt for 17k euros in case of interest
Probably easier to find with Hifishark.
Sorry guys, but that ad is a scam. That turntable belongs to someone in Florida.

Indeed.
Ivor was against it for years.....I have no idea as to what changed his mind! However, it's a very good thing that someone or something did.

Hi Peter,
Hello (in alphabetical order only) Bonzo 75, Scott Brown, Guyser, Microstrip, Morricab, SpiritofMusic and XV-1,
I am the co-conspirator with Peter in this endeavor, having provided the SP10 Mk3 TT discussed in this thread. Part of me wanted to weigh in earlier in this process, but I'm glad I didn't. First, the thread seems to have largely run its course, which affords me the opportunity to learn from 12 pages of responses. Second, from this vantage point in the discussion, I can see how the thread has been treated and perhaps opine usefully upon places where we may have diverged from Peter's well framed inquiry.
May I comment, first, upon Peter's unusual combination of dedication, intellectual integrity, passion, excellent writing skills, and effort to bring to this forum as scientifically balanced and methodologically transparent an approach as is practical under real world circumstances. Further validating Peter's efforts is the coincidental fact that real world circumstances are exactly those under which every one of us listens to music, whether at home or in concert. Wherever we listen, the variables of listening are at the affect of our surroundings, our psyches, ears, systems and personal preferences. Anyone discounting these factors cannot offer --in my not-so-humble opinion (on this matter in particular: I try harder on other aspects of audio-related discernment and discussion)-- cannot bring a balanced opinion to the table. That does not, however, mean their observations are not worthy to consider; it simply means to me that, as with audio and other arenas of inquiry, allowance(s) must be made for the poster's perspective. That the reader must deduce or infer a poster's bias for her- or himself is simply one of the skillsets requisite for an adept and productive use of the forum format. This, too, in my experience, is a milieu in which Peter excels: his questions are not only well thought out, his responses to this and other threads are exemplary for their even-handedness which derives from a genuine desire to learn as distinct from the need to be heard or to impress (to which I have fallen victim more than once).
If I may phrase it this way, our approach in setting ourselves this challenge was to create a real-world comparison between two turntables, the Technics Mk3, that is oft mentioned (and vaunted, rightfully or not) in audio forums, and the SME 30/12 that is neither as well known nor as frequently discussed.
Several things come to mind that I hope will add to this discussion. After reading the responses to date, I find some criticism of the method, but the questions surrounding these objections don't bring much useful insight to the inquiry. The best exception is XV-1's insightful catch that the Micro Seiki platter mat is installed upside down in the Mk3. Thank you very much for noting that. Few if any other readers questioned what specific differences might contribute to the different listening experiences experienced in the two systems mentioned. Part of this may well derive from the limited exposure people have had to the Aurum Acoustics system. That is, however, not as important as it might be, specifically because variables were quite limited. Nonetheless it is worthwhile to mention that while Peter uses a polished steel plate to pre-load his Vibraplane, I use a composite stone slab from a laboratory anti-vibration stand. These must, defacto, have different sound characteristics if you believe as I do that "everything matters" in a listening room, as Derrick Moss, designer of the Aurum gear asserts. Furthermore the Mk3 table is supported on four Stillpoints which may, or may not, interface differently with the aforementioned pre- loading materials. One thing Peter didn't recall is that the Mk3 is of Asian specification, which necessitates use of current modification to derive 100 volts from the US standard 110 volt linefeed. This is unavoidable, but the use of a voltage transformer introduces yet another variable to the equation. To address further the possible differences in just the front end of this comparison, I use a silver tonearm cable with the Mk3 in my home system while Peter's cable is high purity copper. Of course there are the other variables of listening room, room treatment, power supply, electronics and setup. Peter and I both have Vibraplanes under our amplifier(s), preamp and turntable, and our room treatment shares some of the same components.
It may be helpful to describe the reasons for which I selected my analog front end. After listening to Peter's system, and specifically his carefully implemented transition from the SME 10 to the 30/12, by way of first using the 9" SME arm from the smaller table on the 30/12, I determined to my own satisfaction the strong superiority of the 12" arm over the 9" SME. From this learning, I consulted with Albert Porter who was using equipment similar to mine: tube gear (VTL750s, now replaced with Allnic M5000 monoblocks) and full range unvented, cone driver speakers (since supplanted by Focal Utopias) with his Mk3, in the same plinth used in our comparison. Through heuristic experimentation, Albert had determined that the SME V-12 and AirTight PC1 Supreme were a complimentary choice for his gear at that time. This was confirmed by most if not all members of his weekly listening group. The similarity in typology of electronics and the complementarity of the SME arm/cartridge combination was certainly a factor in my selection of the Mk3 / SME combination. Of course Albert's system and mine are not comparable; it was their fundamental similarities that suggested the TT combination might be a good match.
One other way I might mention Peter's approach to system setup and mine are similar is that we each had Jim Smith perform a Room Play session on our rooms. I mention this only insofar as we each learned what a professional would do to draw the most from our individual room-gear interface. Unlike some audiofolk --another opinionated moment disclaimer-- I feel strongly that our systems are no better than their setup allows them to use the listening space to best advantage. Very few of the listeners I know pay what I consider sufficient attention to this option for optimizing system perform
Many of the responses to this thread have been helpful. Beyond XV-1's observing the incorrectly installed copper platter mat, which I greatly appreciate, I want to address others' comments.
Bonzo75, thank you for encouraging Peter to post this thread. Your suggestion that Alber Porter select another arm has been treated above. Interestingly, Albert has moved on from the SME, having determined that his new cartridges, the AirTight Opus and the Alnic Puritas are better served by a 14" arm. I feel that Peter's work has provided an uncommon, and exceptionally useful chance for a fairly scientific comparison of two different, well thought of turntables, one new and one vintage, in the same system. To the other posters who have, albeit complimentarily said "nice thread" or "interesting post", I feel that is not sufficient acknowledgment for the time and car Peter has brought to light in this comparison.
Microstrip and Morriscab went back and forth about cogging: thank you for what clarity you brought to our understanding of this issue. I would simply say that Technics' engineers were clearly aware of cogging as a phenomenon when they specified the coreless design motor for the Mk3. This table was the culmination of thousands of hours of research development and feedback on industrial TT design and problem solving, the likes of which have seldom been matched. The Mk3 was their statement achievement, the best their experience and electronics of the era could create. I find it difficult to believe those engineers, with demonic dedication and few financial constraints, would select a motor without factoring in, and as effectively as possible defeating or working around, its shortcomings as an integral part of their design. My scientific background is limited to materials, rather than functional implementation: I'm not able to comment intelligently on methods to forestall cogging, but feel comfortable in my belief that Technics' engineers certainly knew of it, defined it to their satisfaction (the laws of physics pertinent to the Mk3's design haven't changed since that time), and did everything possible at the time to minimize its effect on the Mk3's sound using their prodigious resources of research, experience and experimentation. This is not to say cogging is not a factor in the Mk3's sound. It is, however, intended to encompass the speed stability tests we applied to the Mk3, in which Peter's digital speed measuring device, showed a rock-solid, unmoving mark on a wall a full (10) feet away (!) from the TT.
Spirit of Music queries, very much in the spirit of the intention of this thread, whether DD or DB typology is too coarse a distinction for our level of systems? Yes, in my opinion and experience it is, for exactly the reason implied in his second, perceptive question that mirrors Peter's thinking: does the sonic result depend more upon implementation than upon the type of design? Yes, again. This is where I believe this thread is at its most effective: the comparison Peter and I conducted has highlighted two things. First, you can't usefully compare air conditioners and dehumidifiers. The two tables are very different, and our systems were selected to some degree to showcase these tables to their best effect. When you think about it from that perspective, ie deductively instead of inductively, how could the outcome have been any different? Peter selected his Pass electronics with great deliberation over many years to maximize resolution and as close a similacrum to live music (which he hears often as a reference). I, by contrast, chose my gear with the intention of having what I consider "Musical" sound. Second, I greatly admire the way Peter's system sounds and how far he has brought it over the years. I also like the sound of my system, though it has shortcomings that I can't at present afford to address to my satisfaction, insofar as I am 'addicted to best' when it comes to more than audio (read c-a-r-s) and have limited spending resources.
Our test was flawed in another specific way that Steve identified and addressed immediately, namely whether we had evaluated Peter's SME table in my system. We didn't, and that would definitely have been both fun and informative as well as providing more scientific and balanced 'data points'. Per the above, I couldn't afford to hear the 30/12 in my system and then have to sell off my Technics to purchase a 30/12, had we come to similar conclusions listening to my system as we did listening to his.
Each of the contributors above added greatly to our --or my-- learning from this experiment. In my humble opinion this represents the best that these forums offer, namely the opportunity to share experience and expertise. It is left to us to tease from the fabric of these discussions those strands that best illuminate the strengths and shortcomings of our hypotheses, and how those light the way to our next steps.
I thank each of you --mostly for wading through my unending twaddle-- but even more for bringing to the table your unique blend of experience, opinion and insight. I feel confident that my system will, sooner or later, greatly benefit from this discussion and from the comments each of you has shared so earnestly. Thank you.

Guyser, though the armboard material was a constant, you might wish to know that Albert Porter uses the same material, Panzerholz, for the armboard as for the bulk of the plinth's body. I do not know what metal SME employs for their armboard.

I’m coming around to the idea that each drivetrain ie belt drive BD, idler drive ID, and direct drive DD, is a series of pros and cons, balances and compromises, and each implemented optimally has an awful lot to offer, and should maybe converge in character more than they differ.
It looks like Peter’s BD SME30 v DD SP10 demo may have been optimal on the SME side, but variable on the SP10 side (platter on wrong way around, motor controller not isolated fully etc), and maybe these needed to be corrected for the DD to give of its best.
To this end, my final shortlist of final final tt that I may buy will comprise a DD, BD (actually string/thread drive more like), and ID. All excellent examples of their type with no compromise engineering, fascinating choices of tech and materials, company flagship designs, and affordable compared to so many SOTA offerings from the usual suspects I can’t begin to contemplate financially.
Well Peter, there are 3 conclusions to draw that I can see.
1- despite a lot of people’s love of DD, that sound difference you heard isn’t for you.
What people are loving as increased jump factor, or more leading edge excitement, you’re picking up on as a colouration that’s homogenising the sound
2- something in the setup/comparison wasn’t right/sub optimal on the SP10 side, meaning this detrimental attribute you commented on was introduced or exacerbated at the session (imagine if speed was out on yr SME and a listener detected it)
3- there are sound signatures that apparently many of us hear and find we like or dislike, even if others are blissfully unaware. Maybe Peter, you find the grippy torque/uber speed control/servo feedback of the SP10 has a trace signature that just doesn’t push your audio endorphin buttons.
Peter, maybe the gist of it is: you like the SME more, and like the SP10 less, both familiarity with yr 30, and what you feel in your bones.
The interesting course would not be to go back to a return match, but compare your 30 afmgainst a current day production DD, that is potentially class leading and as well engineered as your SME ie the new Monaco 2.0.
It’s gathering absolutely stellar reviews, a couple of writers claiming it rewrites what’s possible from analog.
So maybe get the 2.0 over, replicate trial btwn it and your 30 by swapping the arm and cart over.
I suspect this will be a really interesting test of your preferences.
