Hi Peter,

Yes, put me on the list!

Hi,

Because of firmware upgrade I was without the Intona for 2 weeks.
But I prefer the SQ with Intona, more sparkle sound. (maybe edgy?) For me there was no doubt.

As you see in my profile I also not use the higher SFS value of 120 because it makes my bass to muddy. I like the low SFS.
Maybe it is a personal taste. Or just because of the other stuff in the chain e.g. tube amps.

Hi Peter,

Without the Intona and using the mobo USB3 at SFS 120 the white light never came up.
But I did not like the SQ, to muddy bass. So I went back to the low 0.12 SFS. In the same situation no Intona and mobo USB the white light came up every 10 minutes or so.

Now with the low SFS, Intona and the Silverstone USB card I do not see the white at all coming up. So I would say the PC runs cooler now.....

Hi Peter,

Maybe the mobo exchange together with the b'ass upgrade?

But I am happy with the SQ I get now.

The PC seems to run cooler. I do not see the white light anymore although the SFS is low.

Hi Peter,

Found my silverstone with Paul pang clock back put it in and it sounds not bad at all. I like it for now.

The front USB is not a real solution for me. Only for testing.

Thank you also for the help.
Maybe I will buy a second mobo as spare? Will wait for now.

Regards, Arjan

Hi Peter,

With the front usb there are no errors. So you nailed it.
And balance load is on 43 again.

What I can do next (tomorrow) try a Silverstone usb card.

Or do you have other suggestions.

Hi Peter,

CPU speed has influence.

With boost off the workaround altX is not working anymore. Also then I have errors.

With boost on after altX no errors.

Also with boost off I almost always get the "Attempts: 11 Current CPU% level of process : 6.433237. Continue?" Yes/No. And with Yes music starts (with ticks)

With Balance load on 100 there are no errors when music plays unattended! (with or without altX).
But the errors are still counting when music stops.

Also it seems not possible to go much beow the 100. Maybe 98 but with 95 I get some errors again.

It has to do something with CPU speed.

Hi Peter,

I did some testing. With cheap usb there are no errors at all! The errors are only existing with Clairixa between PC and Intona.

USB3 (only driver control panel)
With just the driver control panel open the Errors (USB and Fifo) are starting. Within 1 minute the USB errors are 500 and FIFO 2000. At 16ms it seems to be a bit worse but this is not consistent. (all counts are average per minute)

USB3 xxhe unattended
The USB and FIFO error count seems more depending on the buffer size. 4ms 500 and 2000 and 16ms 1500 and 10000. (per minute)

USB3 xxhe unattended + altX
No errors!

After altS the errors are still counting.

I also tested it via USB2.0 and the results are different. Almost no error with just driver control panel and unattended playback but errors after altX. So the otherway around.

I checked your remark about 8ms an 44100 but I did not see any different behavior with that setting.

Maybe you see any logic in this.
 
I am thinking about buying a second Intona and just see how that behaves. Also errors then I will send it back.

Hi Peter,

Can this be done while unattended? How?
I did not tried it but just a question.

regards, Arjan

Hi Peter,

I did some further testing. The grounding did nothing.

But, I only get the USB and Fifo errors running unattended!
And after alt-X, when the screen is up again, the ticks are gone.

So I have a kind of workaround to avoid the ticks in unattended, do alt-X directly after the music starts.

But maybe you have an idea what is going on?

regards, Arjan

Hi,

Firmware is update, but the issue still exists.
That is a pity. Maybe my Intona is wrong somehow.

Will do some tests with the grounding switches first.

After that I will contact Intona.
I am thinking about buying a new intona. Just test it, when okay I keep it when not okay I will return it.

regards, Arjan

Hi Peter,
Very good news actually. Now it becomes (one of) the cheapest upgrades again.
Yes, put me on the list for this upgrade!

When can I bring in my NOS1a?
Regards, Arjan.

Hi,
Intona advices me to do an firmware upgrade.
I will do that first.

Regards, Arjan

Hi Mani,

Thanks for your reply. I will contact them. It makes sense that it is the Intona.
I already had some issues with my Intona in the past so it is now time to solve it.

Regards, Arjan

Hi,
Got my Stealth Mach II last Friday and I like it very much. But.....

The combination with Intona only works with a cheap USB between PC and Intona. And not with the Clairixa in between. I get fifo errors, hiccups in the sound.
The Clairixa between Intona and NOS1a is no problem.

I also tried to switch the short and long Clairixa's but same result. Two 'broken' Clairixa's? I do not think so.

I remember that I had the same issues before with my old PC. But that was solved when I changed the PSU used for the USB card. So it has also a relation with the new lineair PSU of the Stealth.....

Are there others having similar issues?

So far I think it might be an Intona issue. But before contacting them I would like some advice.
