I have been playing around with my new 30cm cable, but I can't let it fail.
Of course it must burn-in or maybe burn-down Happy but ...

Generally we can do two things :

1. I send you both a new cable to see whether that helps.

2. Arjan comes over with his Intona and Clairixa (maybe even both) to see whether it's the Intona.

Ad 1.
Not much helpful if it doesn't help.
Unlikely to help.

Ad 2 (a).
Always the most helpful because it can be combined with a new cable just the same, if the Intona appears to be OK.
The latter is unlikely, because the former already is (see 1.).

Ad 2 (b).
Not helpful at all if it appears to be the combination of PC and Intona and cable.
Likely.

I wasn't trying to make fun, but reason out chances. And it is not so easy ...
What I suspect is that the Intona is not equal for everybody. Reaons for that are :

a. There is timing involved which is at the nano-second level.
b. Intona is improving firmware because many others (not our group) have issues (can't get it running at all). So what if you received new firmware which now for "us" doesn't work out the best.
c. It is already clear that it is impedance or whatever cable related.

Ad a.
With the knowledge of the galvanic isolation of the NOS1a in similar fashion (but in another (i2s) domain, we know that this is also "external chip" related. So if a delay of say 2ns is required somewhere, then another chip or even resistor etc. can make this a required 4ns delay.

Ad c.
This has been proven by many (in unsollicited fashion) and not even at the high speed we NOS1(a) users use. Read : not all USB cables work (more not than do) which actually testifies about #a. Notice that this is also how the length can matter.

Then we have this as a kind of facts :
- Clairixa-"long" works for everybody;
- Intona with $1 or whatever cable, also works for everybody (so far), except for maybe one that I know of.
- My first Intona didn't work for long, dedicated (by me) to "heat" problems (just a little warm up and the timing changes (too much)).
- All short Clarixa's were tested over here, in a chain similar to your daily use if not 100% the same for many.
- It is only two that don't work but with not too many others around yet claiming that it does work (we sent out 30 short Clairixa's, so that many Intona's should be around too, in our group).

scratching

I am just thinking ...
I am pretty sure that everybody with an Intona from our group (so 30 at least) used it for at least a few days by now (if not a few weeks) with his Clairixa at the DAC Side. But I now wonder ... If these same people would have used the Clairixa at the PC side, whether not all (or many) would have had problems ...

Hi Peter,
Not sure i was clear enough but long Clairixa between pc and intona also gives errors and ticks.
Yes, might be the Intona, but the Clairixa is also involved.

Will try to do a test later tonight with mobo usb. And maybe some other USB cables?

Yes, that was clear Arjan.
I suggested that this might have happened to more people *if* they only had tried (which I guess nobody did).

First there was Clairixa and then Itona. Only Clarixa no fifo and usb errors. The sound of these errors are very audible!

Not NOS1a but using Intona too. I switched the short standard USB cable and the Clairixia USB cable and compared the transmission errors counted in the USB receiver of the DAC. In both cases roughly the same error count is shown: 250.000 KS transmission packets and 400 KS error packets (should be syncronization). The plugs of the USB cables are isolated with sticky tape to cut the screening reliably and I'm using a standard Intona.

I did some tests with W8 (not the OS ramdrive), with and without the Intona. I have a Clairixa USB about 1.5m and a iFi USB cable that came with the iFi iUSB (bought two years ago).

When not using the Intona, I connect PC and NOS1 (not NOS1a) with Clairixa.
With Intona, I connect PC > iFi USB cable > Intona > Clairixa > NOS1.

In the two cases there were errors at the end of the playlist with KS. So for me the Intona is not necessarily the culprit.

But I realized something else. I needed to elevate the SFS and slow down the ClockRes to eliminate some other errors (USB and Fifo). At this point, I still have to compare with and without the Intona though.

I Have tried all of the mentioned scenarioes, with supra,  entreq and a common usb cable, on one side, and clarixa on the other side. Switched cables from and to DAC and pc-side. I had the same distortion as you. But I gave up trying. Switching between cables and adjusting sfs value. I played with sfs 0,06 and 4 ms.   and I have no distortion anymore.

I tried the mobo usb instead of silverstone with the short clairixa to intona and that works without errors and ticks. So for my setup also the Silverstone is part of the issue.

But I still prefer the Silverstone.... so back to cheap cable between pc and intona.

But oh boy getting into bios to activate the mobo usb was difficult. PS/2 mouse and keyboard do not work..... I first had to reset the bios and boot without hdd attached. With hdd it was for me impossible to get into the bios. But this is another subject.

I received the package with RAM-OS disk and short Clairixa cable yesterday.  Spent some time today listening with my standard setup (see signature) and short Clairixa cable between PC and Intona.  No problems, in fact better SQ than using the cheap, longer USB cable I had before.  Not sure this helps anyone, but just some input.

Ah you encounter problems too with the PS2. I think ill buy a new USB card with 4. So I can connect mouse, keyboard and HDD dock. Than the MB USB can turned off again. I also got in when I removed HDD-RAM.

Thanx

People, there is a topic in the Chatter board about a perceived BIOS and PS/2 connection problem. It was named "boot menu" and I just renamed it to "Problems getting into the BIOS (with RAM-OS ?). Here :

I received the package with RAM-OS disk and short Clairixa cable yesterday.  Spent some time today listening with my standard setup (see signature) and short Clairixa cable between PC and Intona.  No problems, in fact better SQ than using the cheap, longer USB cable I had before.  Not sure this helps anyone, but just some input.

But of course this helps, because it testifies (or sould do that) that things can work.

Thanks,
Peter

All,

During my testing yesterday, I definitely found that - at least in my situation - the Buffer of the NOS1 Driver Control Panel can not be at 16ms. That is errors all over the place.
Disclaimer in favor of Intona : I did not sort out whether this is "caused" by the Intona and I vaguely recall that this is since the "a" of the NOS1. Anyway that can not work while the install of the Driver defaults it to that.
Side note : the ClockRes appears to be involved in this, as it being at 2.5ms the errors are almost away. So Driver at 16ms and ClockRes at 2.5ms could be an acceptable combination - for me over here at least.

I Have tried all of the mentioned scenarioes, with supra,  entreq and a common usb cable, on one side, and clarixa on the other side. Switched cables from and to DAC and pc-side. I had the same distortion as you. But I gave up trying. Switching between cables and adjusting sfs value. I played with sfs 0,06 and 4 ms.   and I have no distortion anymore.

Hey Arnt,

First off, thank you for sharing, bbbut ... it is not so clear to me what your conclusion and final setup is.
Also, you have the short Clairixa and seem to avoid mentioning that you used that together with your long one.

Is it possible to briefly tell it in a somewhat better fashion ?
Thanks !
