Best volume knob ever was the long discontinued Emotiva Control Freak. Best one I've found since my CF passed away is the TC Electronic Level Pilot X.

I agree on the Emotiva CF, when mine started showing signs of ill health (one chan NOP, but never trouble shot it down to confirm it was the CF!), I replaced with the JBL Nanopatch, and tho not anywhere near as elegant, handles more types (IRCC both bal and unbal), & includes a mute feature, which the Emo was sorely lacking (it
begged for a
slap to mute capabality!). I considered the above, and like the 'view' but wasn't sure about the quality.
But this was for use on my desk, & not wireless.
For the big system, I finally went all balanced analog (I had had some AES channels) and now use the tiny little apple remote with the OktoDAC as my main volume control. I love it. Only downside is that it has a tendency to hide.
I'd like to try the MS dial thing on the WinPC/Jriver, but suspect that's a
Thing Too Far.
