I agree. If you’re that pitch sensitive, go digital or fork out for the Nakamichi.
I collect test records. The variation in W+F between them is vast, as is the the difference between runs. Pressing a test record is fraught with danger, as the 1st run might have the centre punched nicely, but the second could be well off. I've seen people claim 0.025 W+F on the Tacet 2014 test record, but the example I've tested couldn't do better than 0.12% (>0.1 is considered audible).
The DS Audio gadget is certainly a nice toy to have and good luck to them for developing it, assuming it works as advertised. I like to have a glass of wine with my weekend vinyl session and I'm not sure that getting the hole punch out is compatible with my listening habits. Maybe I need the Nak...although recent sales prices are somewhat of a deterrent, as would be parts availability.
NB - the best TR I have gives 0.03% W+F (B+K from Denmark), and this is confirmed via testing on many TTs. The TT's inherent W+F will increase the overall reading, but speaking as someone who's auditioned numerous TRs for the purpose, I've found that the hole centring of the record in question invariably swamps any qualities of the deck itself, assuming the deck is in VGC. I know that a 'good deck' with the B+K gives 0.03, so more and I think deck needs a service. The best method to test W+F is optically, taking hole centres out of the equation. However, all bets are off once you place a mystery record on the deck and the measurement becomes academic... But we aren't bothered about that which is purely academic, or we wouldn't come here in the first place -)
