Topic: Mysphere 3.2 and ADI-2 Pro / DAC
I’ve published an elaborate EQ for the Mysphere 3.2 and ADI-2 Pro / DAC.

Here is my take on an equalizer setting for the Mysphere 3.2.
It was created over a period of three months.
I started with some measurements.
Through a lot of little tweaks and version comparisons by ear, with all kinds of music, I ended up with the setting below.
Made for the RME ADI-2 (DAC or Pro), but can be used on other systems too.
For me RME ADI-2 Pro / DAC and Mysphere is a dream-team.
Important to know:
My listening levels are between -30 and -40 dBr with ADI-2 Pro’s Auto Reference Level on.
The resulting Peak Voltage level is about -8 dBu = 300 mV = 0.9 mW, with typical pop music track.
With more dynamic mixes the figures are -2 dBu = 600 mV = 3.5 mW Peak.
The resulting Sound Pressure Level is in the range of 65 dB LEQ, measured at ear entrance.
So this setting is made to be used at ear-healthy, moderate loudness levels.
Vocals in the music are at about peoples normal talking level.
I use the Bass- (B-) Pads, but due to some distance to the ear there is only neglectable bass-boost, compared with removed pads.
I position the Mysphere 3.2‘s driver’s center a little bit higher than my ear entrance.
The drivers are angled by 28° (Cut a plastic card as angle measure).
I can just put my little finger between driver and pinna.
By shifting the drivers up and down one can change that signature quite some, up = lighter-, down = fuller sound signature.
Similar applies to the driver’s angling.
In my multiple measurements I found, the midrange sound signature is quite consistent with various positions.
The EQ uses a 27 Hz Hi-Pass (low cut) Filter with high Q.
This boosts the bass and removes sub-lows that Mysphere does not reproduce, cleaning up the sound.
The Treble Shelve Band is not used (Gain = 0 dB), frequency and Q are pre-set to adjust treble to taste.
Band 5 and Treble Band settings can be swapped if one needs more detailed tweaks.
