@austinpop , I found some pictures...looks like there is a fuse inside. https://www.head-fi.org/threads/ayre-acoustics-codex-dac-headphone-amp.750809/page-53

I wouldn't sweat it. Just enjoy it since you don't have this issue. I suspect the Codex doesn't like my source feeding the music. In any case, I've wasted enough time on it. :)

Curious...what revision version are you running? I'm running 1.3. Good for you :). Honestly, as good as the Codex is I've upgraded to a discrete R2R ladder DAC and it's a significant improvement especially for pcm files. I'm keeping the Codex as a headphone amp/DAC but it's no longer in my...

I'm not sure about the usb cable but some users on computer audiophile were saying that Ayre uses volex power cables.

If you listen to mainly PCM files, it seems to be pretty good. If you start mixing PCM files with different rates with DSD files, then you may hear something. Everybody's mileage seems to be different, I'm sure the source makes a difference as well.

No it also happens when using it as a standalone DAC. I experimented with both settings. As long you don't keep flipping through songs in the middle of them, it's not too bad. If you let it play through song lists, it's not too bad.

Congrats! I spoke to Ayre a few years back about the popping sound when changing sampling rates and they basically told me that there was nothing that could be done. We just have to deal with it. It's one the cons we have to live with. The good thing is that the overall sound and value is...

I couldn't agree with you more. Btw, your proac speakers and McIntosh gear seems like a awesome combo so keep on listening.

@Kclone, that's great. I'm glad that for you the DAC is helping for with the poor recordings. Btw, do you have an example? I would like to compare it on my system. With that said, I some what disagree with you, high-end components are designed to play what has been recorded, I don't expect...

My Terminator arrived on Tuesday. I've been running the Denafrips Terminator DAC for about 10 hours now. It's currently replacing a highly capable Ayre Codex DAC. This is my initial impression after 10 hours, so my impression will most likely change over time. This is my first R2R DAC and I...

Actually to correct myself in the audio stream article, they mention that Ayre was testing a Burr-Brown chipset. https://www.audiostream.com/content/ayre-acoustics-codex-usb-dac-headphone-amp-digital-preamp. Every other article reference the ESS chipset. It funny that everybody got it that...

That's interesting since it was always my understanding that the Codex used the ESS ES9018K2M chipset. I thought I remember reading somewhere that they used the AKM in some early demo models but switch to ESS for production.

Any more updates guys? @MiguelPT impressions? Hopefully, mine will come in the next few weeks.

I haven't been active on head-fi for a while, but this new website is horrible. I can't stand using it. Very disappointing.

Getting two 3.5mm adapters should do the trick. One word of advise, be patient with the break in time. The Codex needs 300+ hours to break in. It will be worth the wait. Good luck
