Ayre Codex

Did someone have experienced with the Ayre Codex used as a DAC.
I like the QB9 dsd sound, but i used toslink connexion so a Codex could be good for me.
Yes. I bought one from Audio Connection in Verona, NJ and love it. A QB-9 might beat it, or it might not. There were things I liked about one over the other and vice versa. A W4S DAC2 DSDse can't hold a candle to it on high resolution files. The Codex is amazing.
I have a Rega DAC and looking to upgrade in the near future.  I was considering Ayre QB-9 DSD, then I heard about Codex.  Should I save the money and just go with Codex?  If the sound quality is about the same, then I will go with Codex.  Thanks for sharing your thoughts.
I have both Ayre units - QB9 DSD & Codex.
I find myself preferring the Codex.

rather long FB exchange w Charlie..i asked when R series DAC ?
 His reply was improvements to Codex will yield a killer 5 series DAC...inferred that it might already be better than Q series..
my read of it anyway..

I found the codex compelling.  It is more listenable then the QB 9, even lthough it's a little less analytical. It also has an optical in, which makes it more versatile. And when another compelling around machine appears in the upgrade cycle this will make a killer headphone amp and DAC for the office. 
Can’t wait to see what they come up with for a 5-series DAC. I tried the Codex as a DAC in my system (Vandersteen 3A Signature, Ayre AX-5 Twenty) and it sounded warmer than the Ayre C-5xeMP I normally use. However, it seemed like the soundstage wasn’t as wide or deep. As a headphone amp + DAC I feel it’s definitely top-shelf.
Hi all,

Can anyone with a Codex help me with a question?

When using as a preamp, does USB HID volume control work i.e. can you control the volume of the Codex itself from computer software such as iTunes, Audirvana, etc via USB? Especially anyone running OSX?

I did a listening session at my favorite dealer few weeks ago, the result is clear : the QB9 dsd sound MUCH better than the Codex. 

Hi, Marcge:

Was the Codex broken-in?  To me, Codex sounded a lot better than it was after about 200 hours of break-in.  Also, was the comparison done on exactly the same system setup?  Thanks.


Yes the Codex was burn, and yes the A/B Test was done on exactly the same setup (Aurender, Macintosh, Sonus Faber / Olympica III) with the same song. 

The Codex is good, but compare to the QB9-DSD it's clear that the Codex is not in the same league.

Not my experience whatsoever.

I own both.

Guys can codex successfully drive hifiman he1000 headphones? I was leaning towards qb9dsd plus headamp gsx mk2
For my home theater system, my TiVO cable box is connected to my LP OLED 4K HDR TV that uses a toslink connection to my DAC that connects to my Ayre AX-7e integrated amp.

I wish I could use an Ayre DAC but the Ayre QX-5 DAC is too expensive for this application. The Ayre QB-9 DSD DAC has great sound but ONLY has an USB input and no toslink (optical) inputs.  Are there any options to convert optical to UBS for inputting to the Ayre QB-9 DAC?  My guess is probably not.

As stated above, the Ayre Codex DAC ($1,795) is designed as a DAC / head amp for standing on a desk and not a cabinet (my use).  My retailer really likes the Ayre Codex DAC (used as a DAC) so I should probably give it an audition in my system. The Codex has received outstanding reviews.

Any additional comments on the Ayre Codex DAC or other possible DAC's I should look at?   
Mytek Brooklyn is just under $2k, and the Schiits are all very good.
I like the Codex a lot. I think its performance is just a hair behind the QB-9 DSD / C-5xeMP (I have both) but others have come to the opposite conclusion. One thing to keep in mind is that the Codex gets pretty hot when left on for a few hours, so I wouldn’t put it in a completely enclosed space without some ventilation.

There is a converter for all sorts of digital inputs to USB made by Mutec, called the MC-1.2. It’s a little pricey at $450 new.
