i could be wrong, but from what i understand its a problem with the dac chip so theres a possibility it will.  When i did my testing, the issue was present in both Mac and Win OSes.  Since your Dac uses same drivers the mac OS uses theres a chance it might.  But honestly at this point im losing...

@reiserFS   I guess the clicks others are having are different from the ones im having.  The pops and clicks didnt get triggered by any behavior, they were there the moment i turned on the amp.  They were seemingly random occurances, then eventually a random usb driver crash would take place and...

@Netforce   thanks for the update!  Would love to have the option to order the clear top.  Let me know if you here anything about the usb driver updates.  I had one quick question, during all the shows did you guys ever get a chance to try the he-6 with the 600i?  Ive seen a few people say how...

been a little while, any updates on driver info?

@MTMEtim   HI, i was wondering if you have access to an he-6 to test with the cma600i.  There was a reviewer that mentioned it sounded great but no additional details.  Im curious to know if the 600i has enough power for the he-6

Great thanks for that! that was meant to be a PM but i failed >.>

Hello! my serial number for the cma600i is 10300500138.  Have been experiencing the clicks and pops via usb.  Also, earlier in this thread a questyle rep said there were clear tops available to buy.  I PMed him and got no response, is it still possible to get one?

@MR. Hmm   Hey, i have the 600i and have personally experienced the pops and clicks.  For my situation at least, its not limited to just switching between  pcm and dsd.  It just happens in general if you use usb as source.  I can listen using optical with no issues.  Two representatives have...

I am not sure why you guys are arguing.  Two different questyle reps posted in this thread saying what the issue is.  So that confirms that yes there is indeed an issue running the cma600i through the usb, and hte company is looking at the ak4490 as the culprit.   Just because the same chips...

Hey guys just checking in.  I ended up going with the cma600i and hd 650 (ordered it from amazon uk for 280$) for my first setup and love it.  I was wanting to pick up a a used omni or an lcd 2 and found an lcd 2.1 prefazor and jumped on it.  The cma600i has been amazing and was everything i...

@bSquared64 Thats awesome! I hope there is a quick solution for the akm chip, i was planning my setup with usb in mind so this is the only thing keeping me from fully loving this amp/dac combo.     Been listening to the cma 600i with an hd 650 and an lcd 2.1 prefazor and it has been a blast...

Any specific music you want me to try? I just got a used lcd2.1 prefazor and ive been re-listening to all my old music and i dont want to stop >.>   Ive been using the single end stock cable and this amp definately has the power to drive the cans.  Rich smooth sound and that great punchy bass...

I definately experienced the same problems with the USB.  It was driving me crazy for a while, i would get random disconnects pops and clicks.  I tried using , foobar, HQplayer and jriver seeing if it was a software issue.  I tried customizing as many options as i could change with no effects...

@Treeko   looks like i was beat, but heres a picture anywho since i already uploaded it:     @blinsc   i might have needed to clarify more, but i was trying to say that the 600i does not run hot which is what i believe your saying as well.  As for other amps getting hot, i havent really...

Hey guys, im not sure if ill be any help as this is my first step into the audio world, but ive had the cma600i for a few weeks and ill try to give some useful information.   Shipping packaging: I was looking for an excellent amp / dac that would allow me to concentrate on headphones and...

hey, not sure if you have already found a place to buy, but i found that you can get the hd 650 for super cheap on amazon UK. https://www.amazon.co.uk/gp/product/B00018MSNI/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1  it says 233  but when you go to check out it drops to 194. With faster...

Hey everyone! thanks for the quick responses so far.  Im glad i decided to ask before i bought anything.      Quote:    Ive been doing some research on the questyle 600i and its a new amp/dac.  Have you had experiences with it?   What made it special?  Technically it seems like it would...

Hey guys ive been lurking for a while trying to find a good set of cans for metal.  I listen to most genres of metal but i tend to focus mostly on atmospheric/ depressive / viking black metal.  Up to this point i have been using the ath m50x and its finally time for me to move on.  I have i...
