There have been a few threads in the past on USB errors and SQ glitches resulting from the extreme sensitivity of the Phisolator USB connection. A quick note to document my recent experience. I was starting to get music interruptions and SQ glitches fairly frequently (every 30 - 45 seconds or so). Bypassing the Phisolator fixed the problem but I preferred SQ with the Phisolator in-line.
Tried various buffer settings 2ms, 4ms, 8ms, 16ms--none of them really worked. Replaced the Phisolator USB cable that came with the NOS1 G3 with a short Clarixa cable I had laying around. Much improved! Whole albums without a glitch!
There have been discussions on SQ with and without the Phisolator. My experience is that Lush^2 with the Phisolator gives me the best SQ. And as far as Lush^2 configurations go, I really like A: xWYxxx B: xWYRxx. I have jumper caps on the unused pins.

I dont know if you have seen this post. The problem I had is likley to be a very rare failiure but I had a VERY fustrating time solving similar clicking and viariable sound quality symptoms that were localised to my NOS USB input. It turned out to be an intermitant fault on the NOS's short USB cable. Full details are here, its very simple to rule this out, just swop out the short USB cable with another USB cable and see if you still get the clicks. http://www.phasure.com/index.php?topic=4099.msg44030#msg44030Kind regards, Nick. |

Nick,
This seems to be precisely the problem I had. I replaced the short USB cable with another one, a short Clarixa that I had from when I was using the Intona box. So far it has worked well. Very few, occasional glitches, but nothing like before.

Hey Ramesh, Result ! It drove me round the bend when I had the problem. Even a change temprature would send the resistance of the d+ d- lines all over, let alone touching / moving the USB cable. Sound quality apeared to have mind of its own until it was fixed. I hope this is the solution for your system. Kind regards, Nick. |

Even a change temprature would send the resistance of the d+ d- lines all over Nick, how would you know the resistance of the d+ and d- lines ? And what does it mean, "all over" ? I'm asking because I have no idea what you are talking about. Thanks ! Peter |

I'm asking because I have no idea what you are talking about. Thanks ! Peter Peter hi, Take a look a couple of posts back in this thread up at the link I placed in my first reply. The d+ d- resistance is the measured resitance of the short USB cable data lines that went bad. Regards, Nick. |

Hi Nick, Won't bother you with how the issue was isolated, but it turned out to be the short USB cable on my NOS1. Once it was pinpointed I put a meter on the short USB d+ and d- pins. The resistance was all over the place anything from 100 ohms to a few K ohms ! The culprit was the moulded connector at the small end of the cable. Move the cable near the connector and the resistance went anywhere. I am afraid that I had read that, but this is exactly the part that doesn't make sense to me. You imply that you connected measurement wires to the d+/d- pads somehow (how ??) and you say that you move *the* (??) cable near *the* ?? connector and that this influenced the resistance. For me this is 3 parts I each don't understand. And oh, I am not saying that something is not - or can't be true … I just don't understand. You seem to move the cable in a magnetic field and then the resistance changed ? … So now you'll understand how I read your text, OK ? Peter |

You seem to move the cable in a magnetic field and then the resistance changed ? … So now you'll understand how I read your text, OK ? Peter Hi Peter, Its nothing complex, just a faulty USB cable. The d+ d- pina in a USB cable are the data differential pair (sure you know that). The resistance measured was from the USB cable's A type connector d+ to the B type connector d+ pin (same for the d- pins). The cable's d+ and d- wires had a physical connection problem inside the cables moulded B type connector on the cable. As the cable was put under any physical stress (eg bending) the resistance which sould be close to zero ohms for each data line went all over the place from a few ohms to 10s of K ohms. Amazing that the NOS worked with this problem in the short USB cable. All I am describing measuring the "broken" cable on its own. Cheers, Nick. |
