American Sound, "The Absolute Nothing"

a real shame, he brought a joy to any thread he was on and to the hobby. rubbed off on everyone. we are diminished without him. but he has a wonderful young family, so i'm sure he is fine. myself, my kids were my focus when they were young, boats and games and just enjoying them. would quickly trade hifi for doing that again. or for grandkids even.
i suspect when his son graduates from High School he will maybe seriously consider jumping back in.
His system is in his office and he goes to office and is expanding business, so different from usual home systems
but passion for any hobby needs a degree of personal priority that we CHOOSE to give it. if the passion is reduced the tendency to listen wains.

In part, the steady speed is the result of the huge mass and ultra low friction bearing. It takes half an hour to stop the platter from a free spin at 33.33 RPM. That is remarkable.
many other tt's like that. i don't think WBF is any more guilty of this price=value than any others that even discuss these type products.
It is, by quite a margin, unless you are on audio exotics

I own the AS 2000 controller, speed is contolled by frequency and can be adjusted manually on the front panel. The controller also has provisions for automatic adjustment trough the speed measurement from the RoadRunner, but is not functioning in the AS 2000 controller. It can be activated by som swapping of tiny resistors, not recommended for old eyes. It was a miracle i did not destroy the circuit board during soldering
David did not require the RoadRunner feedback loop for his design. I have installed a toggle switch that can activate/deactivate the automatic adjustment in my system.It uses "a Variable Frequency Drive (VFD) that uses Direct Digital Synthesis (DDS) to generate the sinewave signal. The Eagle is a 2 pc supply with the controller nearly identical to the Falcon PSU and a separate high power amplifier unit that can be located remotely. The two are connected via a 6ft 3.5mm stereo cable. The unit uses an Atmel AT89C52 microprocessor to control the DDS circuit, the display and accept commands from the user. The clock source for the microprocessor is an 8.388608MHz crystal oscillator with a frequency stability of .01% (100 PPM) and also serves as the reference source for the DDS. The display uses 3 seven segment LEDs to indicate speed and the front panel has 3 buttons to switch between 33/45 RPM and to control the output frequency for each speed in 0.1 RPM steps. The front panel buttons also access a number of set up and programming modes."

most other high end forums are brand, or DIY, or dealer, or topology/transducer type focused. a different thing. participants are quite narrowly grouped. or very light traffic.
WBF is broad based, and runs the gamut of seriousness and approaches. price=performance will always be a part of the mentality to some degree. too much or too little depends on your viewpoint. hey, you get to do your NLF stuff.....so it's open minded. healthy. always ebbing, flowing.
perfectly imperfect.

What was the sonic advantage to adding it, compared to others you tried
That answers my question very comprehensively! Thank you very much, Milan!I own the AS 2000 controller, speed is contolled by frequency and can be adjusted manually on the front panel. The controller also has provisions for automatic adjustment trough the speed measurement from the RoadRunner, but is not functioning in the AS 2000 controller.

It was not clear to me from the way you asked the question whether you were talking about platter speed, or motor speed. Milan answered the latter and I answered the former. In the case of a high mass string drive design like the AS 2000, the motor and the platter are responsible for maintaining steady speed. It’s different for other drive typologies.
Milan had a very comprehensive answer for the electronic part
Well … Thats a beautiful analogy Mike , and one plausible reason as to why Tang has apparantly decided to walk away from his current HiFi system … Another possibility being tho that he has become disillusioned with the current HiFi system that has replaced his previous very well sounding and trouble free installation , Perhaps Tango as demonstrated the self awareness to wake up from the enchantment that took him down that particular path ? We read stories of survivors of indoctrination from time to time.
I have gone trough a few different models of PS Audio power regenerators and other models of Phoenix Engineering controllers. The fine adjustments on the PS Audio where only good enough on the P 500 model, and not described in the manual, found them only by accident, but sound wise very similar to the AS 2000 controller. The smaller model Phoenix were not powerful enough to drive the larger motors used by me and David consistently . The AS 2000 controller can be set for soft start, and voltage drop after target speed is reached, good for keeping vibrations down. The AS 2000 has a smaller footprint and just enough headroom for driving a larger TT motor. The PS Audio is overkill power wise and probably pollutes the powerline more, a reason i only use these regenerators on separate dedicated lines these days.
Tang has enough money to just buy something different and not worry to much about it. Maybe he just grew up and realized we are on a futile quest, and that means there is maybe hope for the rest of us too !
