Turntable build - Thoughts?

Turntable:
I'll probably go with this aluminium / tungsten platter with a maglev bearing. It's also used in Troels Graversens build if you've seen that before. This is quite a lot cheaper than most alternatives (considered VPI platters and such, but their prices are just outragous)

I just logged in with the hopes you might see this before you hit Secure Checkout on that piece of junk. Avoid it at all costs.

I was moving on a similar path last year and planned to possibly use this mag bearing assembly and platter. It was sold through a number of eastern, grey market audio stores and that big auction site. A few people on another forum bought that assembly. The press fit parts were not trued and the platter was not balanced, and did not maintain a constant ride height. The reviews on the eastern sites also warned of poor quality.

At this point, I’m more likely to go with a commercially available table than fool myself into thinking I have built a high end table using questionable parts. You might get lucky, and it’s not terribly expensive to try, but be aware it likely is akin to other junk items on those sites. A Technics SL-1200 will cost about the same as a kitted out custom table using that bearing, but the SL will perform.

I haven't bought anything yet. May I ask when you read that? I spoke with Troels Graversen (who I think we can all agree on is an expert in audio) and he said the platter was good and he didn't have any complaints about it.

As for the "don't build your own" part. I already have my Luxman, so I'm not gonna buy another comercial turntable.
 
Hi, Quite honestly, if you are going to spend that type of money on a platter & bearing. Then you are not really doing DIY T/T & I would much rather spend the money on a S/H SP10 or SP15 without P/S from Japan
  • Then you know you have top quality parts.
  • There are plenty of guys on forums that can help & have experience.
  • A power supply design of available for the SP10 & quite easy to build.
  • If you place a Topper platter on the SP10 you can use it with a DC Belt drive motor, off board in a Pod (the SP15 does not even need a Topper platter)

So all you need to do is build the plinth.

Cheers

As far as I know, DIY stands for "Do it yourself", not "make a cheaper turntable". As I've stated multiple times in this thread, I am firm on building my own belt drive.

Again, I have my Luxman, and if I wanted the best turntable I could get for the budget I'm building this for, I'd get an Sl1200 - Which I am not getting because I want to build my own turntable.
 
If any of you guys want an update on this build - I am still in the research phase (and I have a lot going on at work so going slow).

So far I am still in doubt about the platter / bearing combo. I still think the FFYX is a good option, however I have other options as well, one is a Pro-Ject platter bearing combo I can acquire for the same amount of money. Other than that, there is a few other options as well, that are a bit too expensive for my taste. I want a very heavy platter which is hard to get from vintage tables.

For the motor and controller, I am in between using the premotec / Zeus combo and using a Maxon DCX motor (with a high resolution encoder) coupled with the Maxon ESCON 36/2 controller. The maxon combo is used in both continuum and kronos tables, so I don't doubt it's quality. I will have to spend more for this though, in return I think the speed stability will be a lot better because of the encoder that has a vastly superior resolution to the Zeus tachometer (as for noise, I don't think there'll be any improvement with maxon).
 
That may very well sound better and be cheaper, but I'm going belt drive for the appeal... If I just wanted a nice turntable I'd probably just get a Technics tbh... This is both a hobby project and it's to give me a turntable I feel like I want to listen to (sentimental value). Judging by pure sound quality, I'd probably just stream anyway.

You can learn a lot from building and testing TT's. Get yourself a stethoscope and listen to the platter and plinth, If you can hear sound via the stethoscope the cartridge will also hear it. Play a CD or other material and listen.

I've built quite a few TT's now all based on the SP10mk2 motor and I have benched marked them against a Goldmund Reference and TeshDas AF3, in both cases the SP10 based TT beat them. In the case of the Goldmund we swapped tonearm/cart between TT's so the only difference was the TT.

What I've learned over my time is the plinth and platter make the biggest improvements. I prefer POM platters and that's all I use now. Usually 30-40mm POMC bolted to either the stock SP!0 platter or a custom aluminium one.

First pic is my TT on the stand bench marked against the Goldmund the second pic is the latest TT I built for a friend.
