Hi guys. I haven't been around in quite a while, but upon reading this thread today I just have to put in my 2 cents worth for Sota, in particular the Star Sapphire vacuum hold-down table. If you are in a hurry, skip to the last six paragraphs.
My Star Sapphire came equipped with an SME V arm. I've had this setup for about 3 years now. I was very fortunate to acquire the table used from a hi-fi dealer for only $2500. I had been reminded by a friend when I went to look at it that the deal was a steal if the arm was in good shape. Never mind the table! The arm appeared in perfect condition. Balancing it to zero weight and then gently tapping up, down, and sideways revealed no points where it was hanging up. The table looked perfect, with its old smoked acrylic dust cover and beautiful Koa wood veneered plinth. The sound of this unit in the store was terrible, and I snatched it up in a heartbeat. For some reason unknown to me the owner gave me $400 for my old Pro-ject 2.9 Wood TT. Maybe he couldn't see that it was completely worn out? So for $2100 I've got the arm, the table, and a MC cart that I can't really recall the name of any longer, maybe because I never used it and no longer have it, or because I'm getting old, or both.
With the unit at home I installed one of my low-output MC carts on the arm, tightened up the screws in the armboard and made sure everything else was snug as well. The table still sounded really unimpressive. To make a long story shorter I concluded that the bearing needed to be changed. This is not something a person can do at home. So I removed the platter and bearing assembly, carefully boxed it up and sent it to Sota.
For $700 they completely rebuilt the platter to the same specs as their Nova and Millenia tables, rebalanced it, installed a new sapphire inverted thrust plate, and provided me with their top-of-the-line zirconium ball bearing. Incidentally, I want to mention that Sota told me they use TufOil engine oil treatment in their bearings. This product is in the Guiness Book Of Records as being the world's most efficient lubricant.
Firing up the table was a pleasant experience this time! The music sounded really good and it got even better. I believe there was a break-in period for the bearing of several weeks, as playing a tone on a test record told my ears the sound had become more stable after this time.
OK, the real reason I posted today is to expound on the virtues of the Star Sapphire that I own, so here it is:
1-
Someone insinuated that the vacuum might not, in fact, be a great thing to have on warped records. Well, only if having every record play ABSOLUTELY FLAT is not desirable would that not be a good thing for warped records. IMO, once you have vacuum hold down you will always want it. It is, for me, a real joy to watch the table and not see the arm going up and down because the record doesn't lay flat. I have one LP which would not even play on my old table- the cart would jump right out of the groove, due to a bad warp. The Sota plays it just fine...

180 gram records? Who needs 'em? My Sota table with its vacuum enabled, impedance matched 17 lb. platter has the cartridge fooled into thinking that every record it plays is a 17 lb. chunk of vinyl.

Contrary to what I have seen posted and/or reviewed, the vacuum system is absolutely and completely silent. Period. And this is a system that has never been touched. Except for the platter rebuild the vacuum system is over 25 years old.

Speed stability. I once saw it posted on this forum that the speed control pots Sota uses are inferior. Not so. The pots on my Sota table are more than 25 years old. I can go for months and not use the table, yet when I fire it up it runs at the same speed I had it set at. My belief is that people who complain about speed instability have temperature and/or humidity fluctuation issues.

I like having a table with a dust cover that works!!! Since the platter and armboard are not bolted to the plinth but are suspended from the top using dampened springs it is possible and very desirable to play every record with the dust cover down!

Looks. No ugly chrome and shiny metal on this table. It is very organic looking. I give it a 10 out of 10 for good looks!
