3 New UBER Decks - Is this Turntable's SwanSong? 🦢

@rauliruegas, I think the problem with record manufacture is a matter of cost and what the market will bear. It is possible to make a near perfect record but this means higher tolerances and more maintenance. Pressing records is not a laissez faire operation. Every record is pressed in 30 seconds under some ridiculous amount of pressure. I think I read 2000 psi. at 350 degrees. All this is going to put a lot of wear on various parts. These machines require a lot of maintenance. 
This is no excuse for record stampers punched off center. I believe that is due to operator error.

Richardkrebs, give me a break. Show me the perfectly flat and concentric record. It is not my fault that this makes your work somewhat less important. I have no irons in the fire. It might have been better if you just admitted that these irregularities do cause changes in pitch that might mask turntable speed irregularities. We all want accurate turntables but there is a certain degree of insanity in this. It's just like cars. "My Porsche goes 200 mph." "But, my Ferrari goes 204 mph." Who the heck ever drives that fast! My Porsche will hold a weeks worth of groceries and I can carry my mountain bike on it's roof racks. Try that in your terribly unreliable and difficult to service piece of Italian rubbish! (just comical relief folks, Ferraris are works of art.)

I am careful to state that these Platterspeed measurements are for “entertainment purposes only”. All test records are faulty as are all records to one degree or another yet I much prefer records to all digital formats. That said, I use the same 7” Feickert test record for every test so while the record isn’t perfect the relative results are 100% accurate. Plus the results in green have been filtered to eliminate the effects of eccentricity. The SAT measurement was better than the SP10R’s. The OMA’s was best I’ve measured. The cheapest CD player will measure better but sound far worse. I’m now using the Shaknspin to measure speed, wow, flutter etc. it doesn’t rely upon a test record. It confirms the excellence of the OMA’s speed performance. As someone who professes to read and trust me you know that I almost never engage in hysterical hyperbole about BEST EVER. The AF Zero, SAT XD-1 and OMA are 3 great turntables and the SAT arm and Schroder OMA arm are the at the top of what I’ve so far heard. Buyers keying off of my SAT review have been in 100% agreement. When I wrote that I’ve not heard two other top
contenders, the Axiom and Vertere, a reader in Asia who owns all 3 said he thought the SAT the best among them. Visitors who got to hear all 3 turntables thought they were clearly among the finest they’d heard though all sounded different from one another, and sounded as I’d written (once the reviews were published). Finally, the poster who claimed I didn’t own a turntable in the ‘80s and had proclaimed digital best is either a liar or an ignoramus or both. I’ve been fighting the vinyl fight since hearing my first CD at an 80s AES. 

BTW your Platterspeed chart is a 30 second test thus smooothing out the visual result. I make sure to always take a 60 second sample

BTW: I never use phrases like “LAST WORD” or words like “STATEMENT”. Those are reserved for hack writers who sit “SLACK JAWED” to products that “RAISE THE BAR” etc.

Edgewear is simply jealous. He’s not heard any of these turntables but he’s eager to call wealthy people fools. That’s interesting. The ones I’ve met are damn smart and not easily fooled.
