WiiM Amp — EQ / Room Correction not reflected in Roon's lossless signal path display

hi all, should I be surprised that enabling Room Correction, EQ etc, on my new WiiM Amp, makes no difference to the signal path as shown by Roon, which remains “lossless”, with no sign of those features being enabled, as seen by Roon?

The WiiM Amp is a Roon Ready product, connected here via RAAT.

Same for all Wiims not just the Amp no DSP shows up at all. I did flag it in a Feedback post about RAAT.

Thanks; I remember reading that, but then forgot about it.

It’s not a problem of course, just surprised me.

I assume that is because the additional processing is happening after the signal is being received by your endpoint (bit-perfectly in your case), so it is invisible to Roon.

Edit: But I don’t know is being certified as RoonReady obligates the vendor to feed downstream processing info back to Roon.

It’s supposed to be transparent and show you what is happening to the signal path at the device end other manufacturers do this. This is one of RAATs selling points. But it seems is easily bypassed or is optional.

Yes I see this in the WiiM Pro Plus, if I use RAAT to it with PEQ enabled in the WiiM app, it doesn’t show in Roon signal path. Sounds great tho using their PEQ with any sources, Roon, LMS etc.
Whereas something like the Kef LS50W2’S show a lot of info of the onboard DSP.

I’ve just ‘discovered’ this too… bought a pro plus so I can group it with other RAAT endpoints (and give the Chromecast back to my daughter… ).

However - should we consider as significant that the WiiM is listed as a Roon Ready Bridge, whilst the Naim nd5xs2 is a Roon Ready DAC?

Hmm…

Should not make any difference they are both streaming/DACs, Roons supposed to show us what’s happening in the inbuilt signal path regardless of endpoint type as long as it’s a Roon Ready device On Wiims it’s not at all.

Is this a suitable question for support?

I made a feedback post some time ago about Roon Ready and this behaviour and how even certification is often bypassed by using ids from devices that have passed certification.

I get the feeling that Roon Ready is a point in time and there’s no procedural revisiting of an item after the initial certification either.
So things can change.

But the PEQ was already out when the AMP and Ultra were released and Room correction was for the Ultra, yet these are the same. The all have to have individual certification. It just seems this feature is by-passable if the vendor wants it.

True - but the WiiM is listed as a bridge.

I think it is what it is. Roon doesn’t see the variable level on the Naim either. But I don’t think I’m going to lose any sleep over it.

Their terminology seems to be really hit/miss as to what marketing label each device as. No way it should be a bridge, although it can be used as one, its main functionality in Roon is as a streaming DAC as all of its implementation is based on this as it has no idea about externally connected devices such as external DAC’s and all its specs are based on this. Hence why it wont allow DoP when it can actually pass it through to an external DAC.

We can always blame the marketing department… :wink:

I actually suspect that anyone who actually cares what’s going on already knows; everyone else just gets confused by the post-RAAT information. How many posts do we see complaining that Roon is up/down sampling the audio when it’s actually the endpoint?
