What frequency clock signal does the turntable need?

Can't remember it offhand, will look it up when I get home.

Ah, got it. X201 is a 4.13MHz crystal and drives pins 4 & 5 of the AN6680 control chip.

"Some people may feel it's overkill, but honestly the improvement in timing and impact of the music is very noticeable. It gives the Ayre a very close race (and sometimes beats it) and brings the sound of vinyl into line with digital. No excess warmth or bloom."
I am one of those people . IMO a correctly working Technics traditional speed measurements are such that any improvement in them would have no audible impact upon a black disk rotating a 33.3 rpm .

That's great news for you then, DQ. Should you ever buy such a TT, you'll be saving yourself the cost of a new power supply. Don't you think you might want to know for sure though, by trying to listen for such changes for yourself?

There are things I am curious about and things I am not .
One thing I am not curious about is whether small fractional betterment in speed stability or wow and flutter will make Genesis vinyl records sound better .
You have to be talking less than 1% betterment . That is a figure I do not worry about
This lack of curiosity is built upon a foundation of 18 months pissing about with ac and dc motors and power supplies .

Ah well, it sounds like leaving well alone might be the best bet for you in this hypothetical situation. Personally, I'd want to know for myself - whether I felt like buying one or not.

Whilst I have some sympathy for that point of view and in the end I would probably say in hifi it trumps mine if commerce is not involved , the counter argument is of course I do not need to buy a pint of mercury to know it will kill me thanks to the wise words of others .
some times words trump empiricism.
If you have a speed variable turntable , you can of course do your own experiment . I can alter the voltage sent to my motor by 0.01 increments .

That's a shame as the multi-regulator mods I performed on the Technics took it to a performance level way outside its price level. The DD motor is of galactic class and feeding it with a near-perfect drive waveform is most definitely audible, despite any 'brain logic' that convinces you the speed stability cannot be audibly improved upon.
You should try to be less vehement when you haven't heard it for yourself.

As always I accept you heard what you heard . I do not accept that I will hear the same thing for the reasons outlined vis-a-vis the infinitesimally small increases in speed accuracy .

I own very few CDs and I don't see that changing in the future - so vinyl every time for me (streaming hasn't yet come of age for me). In what way has streaming not come of age? In the sense that I think that there is significant progress that that can be made (or at least I hope there is).

I cant really be sure of available quality as is, but I want to see advances in bringing this stuff into a more mainstream package. I really don't want to be downloading and updating software or wiring computer bits together. I'd like something akin to a Brennan to be on offer from many high quality makers. I'd also like the same thing without the amp to be mainstream and as user friendly as Apple stuff too. Edit: not sure if any of that made sense, so here's a second bite at the cherry. I want to see plug and play devices available from a range of makers that play CDs, copy them to internal hard drives, then either play them via hifi connection or stream them. I want the user interface to be as good as anything you'd find from Apple. Until such things are everywhere and reports say they are as good or better than a top notch CD player, I'm going to sit it out.

Martin, I can point you to some ways to sort out a rubidium source to experiment with. Im thinking of a 5MHz source which you could reprogram to deliver the frequency you need.
Unfortunately there suddenly seems to be quite a lot of noise on this thread from member danielquinn who seems to be both a troll and a stalker. Perhaps we should take the specific discussion offline?

Doesn't have any of the complexities you object to. simple to operate (no more complex than a cd player) and gives great sound quality. No wiring of pc bit together in fact no pc involvement at all other than the need for a wireless connection for the iPad control interface to communicate. Im sur there are other simple to use equivalents. Hopefully some of them will be less expensive which is the biggest objection. Great feature is remote diagnostics, I had a fault early on and Aurender were able to diagnose remotely and sort out without any interference on my part. That was impressive if a tad scary.

I'm not sure you can get simpler than that!

I honestly hadn't heard of them until I saw a bit in your posts. I think I have maybe tended to wait for something with a Naim,Rega or Arcam badge pop up because I expected that to be a sign of them hitting the mainstream.I will certainly do some reading thanks.
I certainly like the convenience idea of streaming. I used to think I enjoyed the hands-on ritual of vinyl when I had a Townshend Rock. Then I got a Xerxes and found it more fun to use without troughs and screw down clamps. Lately I have moved to a vintage Sony DD which is far less faff to use than the Xerxes and sounds every bit as good. What have I learned? I'm even more lazy than I thought I was........and the less obstacles I have between myself and hearing music, the happier I am.

I'm not sure you can get simpler than that! Still too much for me I'm afraid. I don't want anything to do with PCs, laptops, downloadable programmes or separate DACs. I did run an iPod with a Wadia 170i and DAC but even this was too many bits and too much faff. I want a single box that demands nothing at all of me other than to listen and enjoy.

Hehe laziness is obviously something I really excel at. I knew if I waited long enough I'd be good at something!

This post as me baffled , you say the arunder is good [ it should be it costs 5k ] and as far as i can see you can feed an analogue signal direct to a pre amp , yet you have 30k of clocks and dacs processing the digtial signal from the arunder . Is this correct ?
