VPI's new "Vanquish" Ultra High-End turntable is a STUNNER!

Hmmm my digital cost ~1/100th that and its pretty darn good.  I've heard many others similar that are also very good.   Good digital is not hard at all to get these days.  

My Linn vinyl rig cost even less when I bought it. 

Look a turntable like that is like owning a work of engineering  art that also happens to sound  good. Nothing wrong with that. 

Records have been mostly inherently flawed since day 1.   Getting them to play right is always a challenge.

Yeah, I heard some folks swear by Google Chromecast as pretty darn good digital source for digital streaming 😉
"i assume that they are using encoder interpolation to get the count up to 2560 P/R?"



The encoder ring has 160 poles (80N/80S) spaced every 2mm. This would produce 80 PPR on its own. The pickup interpolates 8x (this is the source of the SDE or subdivision error spec) for 640 PPR. The pickup also synthesizes a quadrature output which doubles the resolution to 1280 PPR. The controller can create a count on both the positive and negative edges of both I & Q outputs so the effective resolution is 2560 PPR.  A count of 1423 for 33.333 RPM implies a resolution of ~0.07% (±1 count or 1/1423) and the software reports an error of 1 or 2 counts almost constantly.  The software can also measure the rate at which the pulses are incoming (W&F) and reports errors as high as ±10 counts although the test record method does not indicate speed fluctuations this high.  It would be helpful if VPI would give some guidance on how they measure a W&F spec 10x better than what is achievable given the hardware configuration.

Funny thing is if they used a slightly smaller encoder ring with 90 poles, it would produce integer results for 33.333/45/78 RPM at 1 sec readings (count=400/540/936).

Don’t know about Chromecast but trust me...I have 4 different digital sources of fairly modest cost by these standards and they all sound very good. 🖖

.”.. encoder with 90 poles... “
Or perhaps run with a higher interpolation multiplier?
