I tried it but my problem stays the same. Dropouts while playing music.

Please, would you let me know where to write the params we need? Where is that file, in the configurator? No. In the new firmware?
How to find it?

I've got my desired setting. How can I apply it to the Expert Pro?

Simply edit the eq.txt file and save it. Then copy and paste it to the root directory of your SD Card with your Expert configuration file.

Is the sound quality better if the DSP is done in the Devialet? It certainly is easier to generate several sets of filters in REW put them in ROON and then you can quickly A/B them.

Well, i have tried put a simple one frequency setting within Roon and exactly the same settings within sweet room. I can tell Roon is sounding much better with this same setting compared to Sweet room, which sounds flat... Or i am doing something wrong.

Not all equalisers use the same formulae and Roon and Sweet Room are different.

For example

Roon
For the Peaking filters the bandwidth in Hz between the half gain points is given by:

Bandwidth = centre frequency/Q

100hz  6db  Q=7.079


Sweet Room
For the Peaking filters the bandwidth in Hz between the half gain points is given by:

Bandwidth = sqrt(gain)*centre frequency/Q

100hz  6db  Q=10


As you can see, the Q values are different in generating the same filter shape.

You can convert Roon filters to Sweet Room filters by using REW.
Within REW, select EQ tab, choose the 'Generic' equaliser for Roon, enter the filter values then change the equaliser to 'Rephase'.

You have shown how to display the difference in REW, but how do we export correct Q values if we follow Mike's suggestions?

He may well add Devialet Sweet Room as an Equaliser together with the generation of an appropriately formatted text file.
