It seems logical that M would allow the 218 to do what many other MQA DACs apparently do, ie pass first unfold MQA from the digital out. Then again, they don’t always do what everyone else does.

Interestingly they don’t say this in the data sheets. From what they do say it looks like the input is passed through without processing. I would have thought that if first unfold was being done, it would be added to the feature list.

A big % of the MQA available is actually 44 or 48k so I guess this is up samples to 88/96k anyway. There is no unfold as such on these rates. M systems upsample all std rate x2.

The first unfold scenario only applies to material greater than 44/48k.

You can decide what the digital output of the 218 will deliver:
MHR or not
Sample rate 1x or 2x

So with different masters and packages the infos are that:

44.1/44.1 EXAMPLE

So for a seldom MQA 44.1kHz MQA master streamed with TIDAL/ROON ,
track info show a packed 44.1kHz stream with MQA resolution of 44.1kHz**

the "IP control" app show "MQA 44.1kHz"
ROON app show "TIDAL FLAC 44.1kHz 24bit 2ch, MQA44.1kHz" **
Sample rate______1x____________2x
_______861......... 44K_________88K
_______DSP..........88k_________88k

48/96 EXAMPLE

ROON app show "TIDAL FLAC 48 kHz 24bit 2ch, MQA 96 kHz"
"IP control" app show "MQA 96kHz"
Sample rate______1x____________2x
_______861......... 96K_________48K
_______DSP..........96k_________96k

48/192 EXAMPLE

ROON app show "TIDAL FLAC 48 kHz 24bit 2ch, MQA 192 kHz"
"IP control" app show "MQA 192kHz"
Sample rate______1x____________2x
_______861......... 48K_________96K
_______DSP..........96k_________96k

44.1/352.8 EXAMPLE

ROON app show "TIDAL FLAC 44.1 kHz 24bit 2ch, MQA 352.8 kHz"
"IP control" app show "MQA 192kHz"
Sample rate______1x____________2x
_______861......... 88K_________44K
_______DSP..........88k_________88k

In all cases the MQA light is on

i dont make real comparements with sample rate 1x or 2x, willdo later on when needed or necessary

Has anyone tried playing with the IP control app settings in /advanced?

In your web browser type in your 218 IP address with /advanced at the end. You will go to a page that has number of options for PCM on/off as well as a yes/no option for "Downstream decoder present". If you have a MQA DAC I assume that would be "yes", With SEs I'm not sure and with legacy DSPs or KII Threes (which I'm auditioning again today) I assume "no".

Thanks for that - how did you find it?
Maybe PCM on/off means MHR off/on?

Do you have an idea about the RS232 settings ?
Maybe I will play around with that.
