One week countdown...

From what I understand, it is half of a room correction. You need to take care of the other half yourself. Let me explain: you need a third-party software / hardware solution (software, PC, microphone) to analyze your listening room. The result of that analysis will show you things like 'you have a 6db dip around 500 Hz' etc. Those data points ( e.g. '+6db @ 500 Hz ) you can then plug into the 'sweet room' config of the Devialet and stick in onto your smart card with the regular config. Sp it is an equalizer but you need to know what to equalize, basically.

Hummm... it´s not a very confortable way to fix the room issues, each time you need to alter something, you change the data in the smart card, input the data, listen the result, if not right try again, etc.

I don't think that is the idea. The idea is that you get an outside tool (e.g. Dirac) to tell you where the dips and the bumps are in your room's frequency response. Once you have them figured out, you only plug the compensation for them into the Devialet config file once. As long as your room doesn't change or your equipment, you should not need to change the equalization. I agree it's not ideal, but then again, it is a freebie.
