        I really appreciated the EQ with several headphones. But with HE6-SE it elevates the bass too far. At a guess it's EQing to a Harman curve.

        Bass EQ should be managed with respect to the headphones. Some need boost, some might actually need a cut.

        My specific Modi MB with v2 firmware has the following DC offset measured at a specific point in time:

        L ch: +416 uV
        R ch: -2.00 mV

        Different times the values may vary by several hundred uV.
        Other units may vary from these values measured.

    My enjoyment of particular recreational music systems is inextricably intertwined with my personal preferences. The following lists are representations of my tastes in music, components and listening levels. The section on music is only a sample of my library but should provide sufficient insight into my musical preferences. I am rigorous and exacting with component measurements. That doesn’t automatically make my opinions worth anything without context. Use the following information to decide how well your own preferences converge or diverge with mine when I make comments about equipment in the forum. DO NOT blindly assume a positive comment from me about some component or headphone will automatically translate to auditory happiness on your part. Likewise you may find yourself enjoying something that I don’t. Consider (learning) your own personal preference.

    I tend to listen at quieter levels where electroacoustic transducers exhibit greater linearity. Higher levels are more likely to have greater distortion and require higher power amplification.
