Hi Neil,
MQA files, as used by TIDAL Masters, provides
lossy hi-res up to 24 bit/96kHz sample rate and only by MQA approved software or hardware. Any so called 'further unfolding' to higher sampling rates, by MQA approved hardware only, is just upsampling,
so no actual audio content is contained in those higher sample rates.
If you really want your Marantz SR7012 to stream true
lossless hi-res up to 24/192kHz, now, without the need to purchase any extra hardware, why not give the
Qobuz a go - with its hi-res
Studio plan (free 1 month trial)?
Enjoy unlimited streaming of your music with Qobuz - 1 free month.
Unlike TIDAL, which supplies MQA encoded FLAC file tracks for streaming hi-res, Qobuz uses normal FLAC file tracks for hi-res - which your Marantz can of course already stream and play. All you need is a Qobuz supporting UPnP/DLNA controller app on your iPhone, such as
mconnect Player (free
Lite version available).
BTW, the only way you can get your
current Maranatz SR7012 based set up to stream decoded TIDAL Masters MQA tracks, is to:
- either purchase a
fully decoding MQA DAC (so
not one of the cheaper
MQA Renderer only capable DACs like the Audioquest Dragonfly you mentioned) and then use the mconnect Player app (which also supports TIDAL Masters MQA) on the iPhone for control (so
not TIDAL's own iOS app, which is not capable of controlling UPnP/DLNA supporting streamers like your Marantz SR7012);
- or,
be tied to a computer running TIDAL MQA approved software (eg TIDAL Desktop app) to output to the Marantz SR7012, which will give you MQA decoding up to the MQA Core signal (aka 'first unfold') of up to 24/96kHz.
