Bits are NOT bits ….. or ?

Late to the party, just came accross the topic.

For what it's worth, I found another issue with Yamaha products.

I use the very same WXC-50 in either pre-amp or player mode.

My Physical set-up is as follows : WXC-50==ToSLink==> RME ADI-2 DAC Fs ==XLR L/R==> iLoud MTM powered monitors.

1) When I send a 192kHz/24bit file from my Laptop over my network to the WXC-50, the RME DAC acknowledges this is indeed a 192 kHz/24bit signal

2) When I use MC-Link (MusicCast-Link & App), and send the same file from another MusicCast device from Qobuz, it ils downsampled to 48 kHz (24bits are maintained though).

So it appears the "in-streaming" source selection to the WXC-50 also matters.

Hope it is useful to anyone, I don't really bother although I needed to see where the "problem" came from ( Yamaha or RME : definitely Yamy within the MC-Link, not the Musiccast "App" per se).

Update : When I input my QOBUZ credentials straight into the WXC-50 using the MusicCast App, I checked I actually DO benefit from hi-res being fed from the Yamaha Device (in "player mode" only) through optical TosLink : the RME ADI-2 DAC fs actually GETS Hi-res input (Checked up to 192 kHz/24 bits - I played "As" fom Stevie Wonder's "Songs in the key of life" for this test).

Did not check the COAX (It's being used to decode my CDs from the CD-S300, which also serves as an digital pass-through for my I-phone).

Bottom Line : You actually get Hi-Res only on the Yamaha machine receiving the internet stream. Any MC-linked MusicCast device gets a dowsampled 48 kHz streaming (24 bit depth is maintained though) : NO HIGH RESOLUTION IN MULTIROOM ON SLAVE MUSICCAST DEVICES.

Side-Note : I Also have a Denon Heos Receiver (3700H thx to Amir's measurements), cascading through pre-amp outputs into a WXA-50 AMP (RCA in) set to -18dB for main Left-Right channels (higher power, less distorsion, thanks again Amir). I just realized there was NO Qobuz App under HEOS. I can stream Hi-Res to the AVR through Audirvana, but need to turn on my Laptop for doing this.

(my personnal french man's) Conclusions :
1) Yamaha and MusicCast while not ideal (like - at all), are a better option than Denon/Marantz and HEOS for music streaming and remote operations.

2) Rather than focusing on HiRes, MQA and s*it, stick to the streaming service you like and possibly offers the broadest support amongst hi-fi manufacturing base (I'm a long Time Deezer user, think I'll cancel my Qobuz subscription soon, wish those 2 french companies merged though). Most now offer redbook CD quality, the high-res content is scarce in proportion (even amongst Qobuz's), and I do not have Time to check if I'm being fed unfiltered ultrasonic noise s*it to fry my Focal Chorus' Tweeters from a catalogue that is largely resampled material from past eons for nostalgic old farts (like me).

3) When are you (Deezer, Qobuz etc...) gonna get your fingers out of your back-end to set up a "connect" function to your front-end and rescue us from the Hi-Fi Manufacturer's Multiverse of Madness ?

Yes - the Yamaha can handle high res. material from the digital outputs, but only in ”player” mode.
Its a pity the ”pre amp” mode does sample rate conversion to 48 kHz on every material , that you can hear as a small worsening of the sound - both from the analog output and the digital outputs. In player mode its really good sounding, but not highend quality. A good computer with a good DDC with reclocking sounds a little better, in my opinion.
