Hypothetical Setup Question

[EddNog]

I picked up a WiiM Pro Plus overnight via Amazon and set it up into my system. I have adjusted the setup as such:
Disconnected Topping D90 III Discrete from the DSPeaker Anti-Mode X2D's digital output and connected it to the WiiM Ultra's digital output (coax)
Disconnected the SVS 3000-Micro's LFE connection from the Anti-Mode X2D
Disconnected Anti-Mode X2D from WiiM Ultra, connected it to the WiiM Pro Plus, connected an SMSL SU-1 DAC to the X2D's output, connected the sub to the SU-1 in stereo RCA, reran room correction calibration.
Added the WiiM Pro Plus to my network, synced the included remote, set up a, "multiroom," group (well, it's the same room) with the WiiM Ultra
Turned on the High-Pass filter on the WiiM Ultra
Set the Low-Pass filter on the subwoofer to match
Used HouseCurve to level match the sub to the speakers

So far so good, sounds at least as good as before, if not better (the SU-1 is a better DAC than whatever is driving the LFE output of the Anti-Mode X2D). Surprising how easy it was to get the speakers and the sub aligned (just used HouseCurve to run repeated sweeps as I adjusted the phase setting in the SVS app).

Result:


I haven't had a chance to test lip sync yet with ARC input; will try later and come back. If it all works, I'm basically ready to add the second sub as soon as I can source a used/open box one in good condition for a decent price, and all I'd have to do is rerun the room calibration on the X2D, which is currently set to 0.2 mode.

Lip sync is fine, but ARC input is completely failing to play any sound. This happened to me frequently prior to this group setup, so I don’t think it’s related. I have analog connection from the TV to the WiiM Ultra’s RCA line in as a backup anyway (however it gets used so frequently that it might as well be the normal connection).

@Wiimer or @Mr Ee are you guys also finding that once grouping is turned on, everything gets limited to 44.1KHz sample rate?

Also, where is the control to adjust timing manually between devices within the group? Try as I might, I can't find any controls for this.

Oh, I forgot to mention that. I'm Amazon music so I can play up to 24bit/48kHz, but Tidal seems to downsample; Qobuz might have been up to 16/44.1.

Yep, grouping has always done this (I'm assuming to reduce bandwidth and thus potential sync issues) although it's 48khz max depending on source.
Multiroom hi-res audio has been on wiim's "thinking about" list for a while, but probably don't hold your breath. Close your eyes (unless watching a movie!) and enjoy it instead

If I told you that I can hear the difference, I’d either be joking or outright lying.

I only realized it was different because of the readout on my DAC.
