That's $225 vs $89. Plus the costs for UMIK-1 or UMIK-2. Plus the costs for a Dirac Live license, if you don't want to use REW.
Not sure if this is what @James! has been asking for.
Don't need dirac license. but yeah need umik1 and experience with REW so not exactly easy to use.
But it does a lot, doubt Wiim can offer something like that...only thing I guess that is lacking I suppose is wireless outputs, ethernet in (to control from app or ideally internet browser) and also to stream to it.
Have one myself. Use it for a triple sub setup in one system and fourth output used in another system so pretty good value for money.
A better easier to use unit would be good for the mass market, just add app control, measurement, PEQ pre and post EQ results, multi sub time alignment, alignment with speakers, etc
