@lewm , now with just a small group we have three examples.
Yes, I am a Sota fan. I just bought one of their top units. But, when I mention what I believe are the best turntables I am careful to include others that I believe perform at the same or higher level, SME, Basis, Avid, Dohmann, Oracle and so forth. If I discount the Technics for anything it is not having a suspension and being adequately isolated. Next would be that fact that it is direct drive which from my experience years ago runs against my grain. They were so bad back then that I have not bothered to look at them since. Maybe they are better now. But, I would never buy a turntable without an adequate suspension. I do not know of a direct drive with an adequate suspension. As far as QC is concerned I think that depends more on the philosophy of the company than on their size. QC is expensive and you would think a large company could afford more of it. On the other hand large companies have investors who only care about profits. Privately owned small companies are usually more concerned about their reputation. I have never seen a bad comment about Sota.
Somebody mentioned the Technics platter being machined from billet aluminum. While that may be true of the SP 10 the others are machined from inferior castings. With a heavy casting that can be fine but with thinner ones you can run into trouble like this.
