I only really use USB for basic internet radio and Spotify, or iTunes, no clicking problems at all - can't help other than to confirm you are a rarity! (I'm wondering if the Caiman is faulty, tbh, given the problem moves from laptop to laptop.)

I did not use any fade in/outs. As for windows sounds i've tried disabling them but sadly it did not make any difference.Quote:

Unfortunately i dont know anyone living near me that has a caiman.Quote:

Yep i am aware of that. The PCM2902 in the caiman is limited to 48khz. I got my laptop inbuilt toslink and the m2tech hiface as a high res transportQuote:

Seems like no here ever heard this clicking noise huh. I might just make a recording of it later on and upload it somewhere online so that you can have a listen to it and see if its something recognisable. I am just wondering if maybe its because its clipping but then again i dont really know what a clipping noise sound like. When i ask Stan on email about it his repl
I have exactly the same problem (clicks on one channel with 24 bit files). I also use a Beresford Caiman. Everything is fine with 16 bits. I wonder if it could be related with the signal from the computer. I use onboard spdif signal from an Asus P6T SE motherboard. It has the Realtek ALC1200 audio chip.
My guess is that it works fine with the CD player because it is 16 bit signal.Quote:

I have managed to play them, and they sound very good, though a couple of files seem to present my network with problems causing buffering. It is I suppose possible that my Squeezebox will tinker with the bits and the sample rate - but whatever it does it sounds pretty good. I'm slightly suspicious as I've also manged to play a 192kHz file, which might be outside the spec of the Squeezebox, and should definitely be outside the spec of the Caiman, so either the manuals are lying, or the data got downsampled somewhere along the way - but what did that?
Next test is to see what they're like out of the USB interface. No sign of any clicks though. [Just tried this - no sign of clicks, though sound maybe a bit hard. On my machine the USB is via the driver which I believe restricts the data to 16 bits.]
I could also revisit DVD-A, which I think is at 24/96. I have several DVD-As which I've played before via the Caiman. They sound great, and unless the DVD player is doing something unexpected, they should defiinitely be 24 bit 96 kHz, or similarly high resolution.
SACD isn't feasible, because of the d*** silly restriction on the digital output. If I had an AV receiver with HDMI it might be possible to do something - though probably just couldn't actually pass through a signal to the Caiman. Not sure if it's possible to do anything with computers which have HDMI to get round this.
To date I've not heard any clicks - which I assume are not just minor ticks, and which I hope are frequent enough that I'd notice within minutes. It's starting to look to me as though you have a specific problem with your unit or configuration.
If you were in the UK I'd suggest going to see Stan, or at least discussing this on the phone, but clearly you have a problem with that. You could try phoning him on Skype though. There has to be some way of getting a diagnosis on this - and then you could decide whether to try again with another one, or have it sent back for repair/modification or some other strategy. If it works OK on some data, then sell it on eBay to someone who doesn't need the highest level of resolution, and get another one sent out.
Ah finally there is someone other than me that hear this as well. Actually your experience is exactly the same the one here http://theartofsound.net/forum/showthread.php?t=4670Quote:

Thanks for trying out all the stuff Dave, appreciate it. If you are interested on hearing what the click is like i've uploaded a recording of my caiman output http://www.mediafire.com/?ynninzwlj3jQuote:

The usb connection clicking sound is actually not that bad when compared to the clicking connection with the m2tech hiface
Actually i've tried started trying using it on my older xp laptop again and give the caiman usb and ASIO a try. Did not spend to much time about it but i think the click issue might have been reduced/disappear. ASIO/KS/DS did not do much difference on my Vista laptop but it might play nicely with XP system.
Sadly though the m2tech hiface still produces click sound with caiman on either the xp or vista system. I wonder what other m2tech hiface + caiman users experiences are. I know there are some member here who have both the caiman and m2tech hiface, maybe i should pm them :)
I'm not exactly sure what i stand here in terms of warranty support since i've opened the dac and swap opamps to investigate this clicking noise and to try the sound changes.
I've had some similar sounding problems in the past and I use a PC as main source.
I used to get occasional clicks or pops through the speakers with 16bit 44.1KHz files but lots of them with 24bit 96KHz files. This was when I was using some cheapo plastic core optical cables. Switching to a Mark Grant coax cable stopped the problem. I've since tried a Mark Grand glass core optical cable that also doesn't suffer from the problem. I put it down to the cheapo cables simply not having enough bandwidth to cope with the high bit rate signals and causing dropouts.
Mark's cables are very good value for the quality they offer, so I'd try one of his in whatever type you need and see if that helps. He offers a money back guarantee so there's no risk.
I'd also recommend checking the various settings on your PC like others have mentioned. :)
If the problem is caused by a mute signal send to the DAC, it might by a matter of the Realtek drivers (or the Hiface but the clicks caused by the Hiface drivers seems OSX releated)
The default Vista drivers simply leave the DAC on all of the time.
What I did on my system
•System: Make a restore point (this allows you to roll back)
•Device manager: deinstall the driver (note type etc just in case you need to download them from the Realtek website again)
•Programs - remove the driver (if you don’t it will be reinstalled in the next step)
•Reboot and Vista installs the MS High Def Audio Device.
YMMV, at your own risk, etc
A couple of configuration tips:

Any chance of getting a copy of the original 96bit file so I can try to re-create the problem?
Yes, I have exactly the same problem. I found that an easy way to test it is to go to on the audio device properties dialog. There you have the "advanced statistics" tab where you can choose the default sampling and resolution. You can choose a setting and click on the test button to hear what it sounds like. 16 bit works well but as soon as I select 24 bit (at any sampling rate), It does not work right. The first test sound (corresponding to the right channel) is often wrong (but not always).Quote:
