Thanks Justin, the CXN V2 website has incorrect advertising then.
I might flick them an email.
Hi again @Justin_Graham
I got this reply from Tech Support:
“The CXN v2 can indeed support up to 24Bit/96kHz PCM signals when utilising the Chromecast connection.”
If you don’t mind, could you please show me a screenshot of your Roon signal path when playing PCM96kHz to your unit?
Only if you get a spare moment of course.
Much appreciated
Hi @allan , is that normal for the Airplay icon to be shown in the above signal path, playing to the CXN V2’s Chromecast input?
That screeenshot shows that the 96kHz file has been downconverted to 48kHz. Also, why is it messing with the bit depth? Using Google Chromecast it should be outputting the original 24/96 file without any processing. Something not right there.
Have you got a CXN V2 too Greg? If so, can you share a screenshot of what happens with a 96kHz file?
Sorry, I don’t have one, but I am using Chromecast with my Nucleus and it plays 24/96 unadulterated.
Greg,
Are you using a Chromecast or a Chromecast Audio? As far as I know the Chromecast devices are limited to 24/48 while the Chromecast Audio can do 24/96 although there are issues using the optical out at 24/96.

The change in bit depth is ROON doing its DSP thing (changed to 64bit and back to 24bit), and the change from 96kHz to 48kHz is in response to what ROON sees from the internal chromecast in the CXN V2, after which it down samples the signal. Whilst it would be nice to get 24/96, I am yet to find out a way to do it, after quite a lot of playing around with settings. Fortunately it sounds good as 24/48!
Cheers

I believe the Tidal Android app now does the 1st MQA unfold… if you had an Android device running the latest version of Tidal app, you could perhaps test, playing direct from the Tidal app to your CXN V2 Chromecast input.
Does the CXN V2 show incoming sample rate on the front display?
Just for testing purposes of course.
Hey Sean,
The sample rate is not displayed while playing Tidal.
When I play 24/192 music over wifi from the NAS- (via chromecast)- it displays 24/192 on the CXN. That makes me suspect that what is displayed on the CXN represents what the original file is, not what is actually coming through to the CXN- I suspect if it could actually do 24/192 via chromecast, they would tell us!. So… it is pretty hard to work out what is actually going on!

Thanks mate. Definitely no chance of 192Khz via Chromecast , as they only claim 96kHz works.
For sure.
Ah well, as you say it sounds great with 44.1/48kHz already anyway.
Thanks for all the info.
I have recently been annoyed by dropouts of the chromecast stream via roon and tidal to my CXN v2. Despite the lower bit rate, I have returned to airplay, which is faster and not dropping out (and to be honest, still sounds great). Is this happening to anyone else? I noted that a new CXN firmware update dropped in the past few days- maybe it has something to do with it?
Shame the release notes are missing , it’s still shows the Jan update there’s been 2 at least since …
Has there been any advance on the metadata issue?
I ask because Cambridge are selling these refurbed for a good price on eBay, and I wonder if I should pick one up to match my CXA-80. And there are a couple of things making me sit on the fence:
Right now most of my house is using Chromecast Audio, but in that room, a ChromeCast-TV is attached to one Toslink input of the CXA-80 amplifier, and an Android box to the other. So buying the CXN at 525 USD would give me 2 more optical inputs, an arguably better (??) DAC than the CXA80, plus it has Chromecast audio built in, so there is less likely to be the kind of delay present when I group the TV unit with the other CC Audio units in the house (between which, when used by themselves, without the CCTV, there is almost never delay).
So I can see certain upsides to buying the CXN. But since I use Roon mostly, perhaps that is overkill, as the streaming functionality of the CXN is bypassed and it would largely be a glorified CC-Audio endpoint, albeit one with some kind of upsampling filter that supposedly helps with sound quality and a better Dac than what comes built into the CXA80. So my question is, would I likely to hear a difference using the CXN if I bought it vs using the Chromecast (Audio or TV) optical out? Cos one workaround to only having 2 optical inputs might be to have both a CC-Audio and CC-TV sharing 1 optical cord between them, switching them back and forth to save the $$$!
Finally, I cannot find anywhere whether Chromecast wakes these units up from idle/standby or not, which would be another reason to consider them. I have learned that Cambridge’s own app will do so, but not whether data flowing to Chromecast will or not. (My 2 NAD amps elsewhere in the house auto-power on, and I love it).
Cheers!
Replacement for CXN v2 on the way
