I loved my CMA 400i but after the USB input went out I've had my eye on something else. I so wish Questyle was a better company the 400i could still be a heavy hitter in the market even in 2020. I was looking at something THX but I think the features of the Topping A90 has won me over. It was...

Sorry to bump this but I have some questions. I have the 400i and my USB input went out and I just seen this. Currently I have a Topping D10 using S/PDIF out then going into 400i just to give my PC connectivity. As you probably know Questyle's support is horrible, like send it in to get repaired...

After losing my whole collection of headphones in the Camp Fire in Paradise CA in late 2018 the LCD-GX are the 1st higher-end cans I have bought. As someone who owned the LCD-2 and the LCD-X once upon a time, I have to say for my tastes I like the LCD-GX better than I remember liking my LCD-2...

Sorry to quote you so long after your comment reply to mine. I can't remember it was something like QMos or something close to that. It would work for like 15 minutes then it would make a one-solid beep noise. The problem I was having this time was a DPC latency issue which I'm still kinda...

Has anyone how has ever sent theirs in and gotten it back? My USB DAC went out then so I went with SPDIF using my MB's Realtek onboard digital out. Now from time to time my audio cuts in and out, lags, and or sound choppy. I don't know if the CMA400i is causing this or this is something to do...

Hey looking for some microphone suggestions for voice and voice-over type stuff. I used to have a Behringer Xenyx Q502USB with an Audio Technica AT2020 setup but it burnt down late last year. I am just getting back on my feet and I would like to make a purchase this weekend. I was thinking about...

In May. They were going to give me a free RMA do to me being a Camp Fire victim. My CMA400i was the only thing my wife saved of mine. Litterally everything of mine burnt down and my CMA400i has become sentimental. It was your comments and others who scared me away from sending it in and here we...

I got a free RMA from them and after reading people's horor stories I will NOT be sending mine in.

I went from the Fostex HP-A4BL to the Schiit Jotunheim to the Questyle CMA400i and I would say it was an upgrade in that order.

I don't know what to do here. Like I said I lost everything in the Camp Fire in Paradise California. When you lose everything but one thing that thing becomes special in ways I can not explain to you. I am no longer homeless but things are really rough for me. Again, I just don't know what to do...

Hey, my CMA400i started switching between DAC and AMP with a click sound on its own. 1st my USB input started dying out and now this. I don't think this thing has much life in it and Questyle support consists of ignoring you until you stop emailing them. damn $800 down the drain. This was the...

They look pretty cool. I so miss my LCD2s and my whole entire headphone collection as they burnt down in the Camp Fire in Paradise CA late last year.

Sorry, it took so long to get back to you. Things have been crazy as my house burnt down in Paradise CA. Saved my CMA400i though! Anyways, it took me some time to get an optical Toslink cable. It's been two days now and it has not switched off. I think you are right something is probably wrong...

I don't even own an optical cable. I'm taking it I need to get one to troubleshoot this thing?

Spoke too soon. After a few hours, my speakers starting beeping and again it was gone from Device Manager. This time I could not use the method as it didn't work. After rebooting a few time it now shows up as XMOS DFU in Device Manager.
