Hello
Can any of the Caiman user tell me if the unit is suspectable to electrical noise/interference (fridge switching on etc). I am getting a random click (like a scratch on a record) in the right channel every so often (I would say at least once in a single song). It seems unlikely to be a fault due to its randomness but am not sure what it could be. I am reluctant to buy a mains conditioner as this may not fix the issue.
Cheers for any thoughts
Sounds like opamp instability, happened to me with certain opamps with 7520 with the caps cut.
If its looking like a possible issue with the unit I will contact the manufacturer
Cheers
Good idea. PM Stan (StanB) he will be helpful, I'm sure. ;)
Hey i got this issue as well. Its an intermittent thing that i want to troubleshoot myself but i havent got the time for it. Did you use yours with a computer as well?
Please share your outcome as i am interested in what is causing it
Hello
I am using a PC. running Windows 7. I am outputing digital coax through a M-Audio 2496 soundcard. Listening is through a naim amp to a little dot IVse headphone amp and sen hd650s. Before emailing the manufacturer I was testing last night. I also borrowed a cd player.
I found that when playing cds last night I was not able to reproduce the problem so if there was any cracking noise it was very quiet. Using the PC I found that at the start of every track there is a very faint crack as soon it started. Then every so often there was a audible crack. I unplugged everything to try my old DAC and nothing. I plugged everything back in and this time it didn't seem to want to replicate the problem after that. I was wondering if this was actually electrical noise coming from the PC as I am using coax and the Caiman is actually picking up every little sound. I must admit I am hearing things in the music which I never heard before (thats a good thing). I have ordered a cheap optical cable to plug into the motherboard just to see if the sound is illiminated.
Yeah i got the same thing as you do. From the brief moments i connected the caiman to the CD player i believe i did not hear this 'tick' sound as well. This is why at first i did not suspect it was the dac's fault and i think its the computer/caiman combo.
Currently i am using my laptop optical out straight to the caiman and i do hear this intermittent 'tick' once every 1-2 tracks. I'm suspecting its my laptop's problem but i've owned 2 dac's before the caiman that did not have this 'tick' problem. I got Vista on my laptop.
I do hope its not a hardware fault and there is some easy fix on this cos otherwise i have to ship it back across the globe.
I am tempted to change the opamp to see how it goes but if i do this then it would void the warranty so i think its best not to do it unless you are sure that dac is not faulty.
I am going to have another play tonight but will wait until the optical cable is used before jumping to any conclussions. If I am still getting the problem will email Stan and ask for some advice.
One thing I did do last night was changed the audio output on the PC. I'm at work at the moment so cannot remember exactly what it was but I had it set I think to 24 bit studio quality in the sound option in Control Panel. I changed that down to 16 bit CD quality. Please bear with me as I am no expert, so I may be highlighting irelevent options :).
Guys I know from experience that the Beresford will output a sight click when the digital output is interupted briefly.
In my case, I was getting it all the time when scrolling up and down menus on Apple TV because the ATV was sending 'click' for each Item I scrolled past. Unfortunately the digital output switched briefly on and off between each one causing a weird noise via the Beresford.
All I had to do was disable the 'Menu Click' on ATV but this wouldn't help you.
If you're using the ASIO4ALL driver on your PC (a good idea anyway) it is strongly recommended that you turn off all Windows sounds, I imagine they might contribute to a similar problem.
I also had this 'popping' problem when plugged in via USB, since I primarily use Coax / Optical SPDIF, this isn't an issue for me.
