If it were for me, not any low jitter USB clock can improve on jitter with asynchronous USB. But and as I said elsewhere, maybe it can after all. It is, however, a 100 times more likely that it is just that other noise pattern doing this (what about very low oscillation because of two now very closely running oscillators at both ends). So, it sure all is about jitter, but the means to it (better pattern up to lower jitter) should be very indirect and should not be about low jitter oscillators in the first place (but mind the low oscillation because then it is after all - hence it is more direct).
But if it works, it works. Sadly also : if it works, what happens with one of the drastical changing software settings.
Just a thought: You can reduce the number of clock variables in the system by slaving one of the USB ends to another. Iow like slave the PC to the NOS clock. Wether this one clock approach works out for the better remains to be seen. This seems to work for recording studios, but then again that is a true synchronous signal. Anyway the low oscillation will not be there. Regards, Coen |

It might even go so far as one end of the link being better running slightly faster or slower than the other. This might point to PPL sync / recive buffering being a factor. Slaving both end is one of the things I am trying amongst a couple of other approaches. The only way to fine out is to give it a try  Regards, Nick. |

Wouldn't it be good if there was only one clock for the 2 USB (emitter and receiver)... It would even simplify things...

First feedback,
Trimming the speed of pc end usb clock.
I was speaking to Paul earlier about the slave clock setup. This reminded me that the sound characteristics I have here now are similar in some respects to a modified m-audio transit card I had years ago (there is a post about the set up on one of the boards). The recognisable sound between the two system arose from trimming the clock speed on the m-audio transit interface (it had an audiocom superclock 4 fitted to the usb interface).
5 min and the trim pot on the dexa clock of my pc usb card clock was trimmed by ear and the same control over sound emerged. One adjustment extreme gives emphasised sharp edge and slightly splashy sound the other super super smoooooooth and clear detailed sound. In between comes a double sized sound stage pure pure detail ultra real just there in front of you sound. Exactly like the m-audio sound but sooooo much better !!!!
The trim pot is hence forth to be know and the "heavenly trimmer", haha.
I love this sound !
Slave (single) usb clock results to follow. Its going to be interesting to see if a set difference in clock speed is better or worse than the same clock speed at both ends of the usb link.
Nick,
Ps variations between systems / usb cards might be in part down to luck of what the relative speed of usb clocks at each end of the link happen to be........ there is a thought. ...

Great work Nick, Now that was a superfast practical experiment! If you hear such differences in sound whilst only offsetting the clock a littlebit, it makes sense that we might be lucky or lost either way with standard "large-but-sufficient" tolerance clocks. This also means that our milages will vary and we could have quite different 'objective' sonic experiences with the same hardware...or different hardware....  Please elaborate on your one clock solution when you get it done. I gather you have to arrange for some kind of clock distribution that is least detrimental to the clock signal synchronicity. Regards, Coen Ps you beat me on this one! |

Wow.Coen, you are a genius; You just brought me THE idea which is so so SO smart that I can't believe it myself. And it has to work. OMG, if this really works then it probably leads to something so devistatingly new that all SQ goes to another level.

This description makes sense. The offset increases (hf?) distortions on one end and filters the sound on the other. It makes one wonder how complex this gets when serious jitter comes into play.... Regards, Coen |

But I think we're catching up Regards, Coen P.s. Enjoy your "popcorn" ! I am sure you are right Coen. These little cultural differences are funny at times...and I am enjoying my popcorn. The cricket is starting so it's time to turn off my music and put on the radio (which sounds awesome through the NOS1...hehehehe). I am watching this space. Cheers, Anthony |
