FIR interpolation phase filter

Function IN/OUT Settings
#1

Hi,

I’m using Rose 150 (not B).
I hear differences when choosing different FIR filters. The super slow is great for high volumes where the sound isn’t too bright and is well balanced. However, in low volumes i feel like the sound isn’t open enough, changing the filter to a sharp roll off filter gets the sound very bright, too much in my taste.

Which FIR filter do you use …?
Is there a “house curve” available per each such filter ? Or more details / experience around this setting ?

Thanks

Meni .

Thanks for the very detailed response.
I’m using the 150 device with the AK4499 based DAC, to what degree is the information provided on each of the ESS filters applicable on my system ?

The filters of RS150 and RS150B are not very different.
Please refer to the picture below.

The filter names are much different, can you let me know what name on my rose is equivalent with which filter name in your table ? (see attached)

Thanks, this is what I was looking for.
I’m using the super slow roll off, and most of the time it’s simply awesome.

Found more info here, for whoever finds and reads this thread in the future.
