What specific configuration of the M³ is that? What OPAMPs and at what voltage? Just curious as I am considering to build one myself and plan to use it with a DT880 600 Ohm. I'm mainly wondering if it's really needed to go with a 40 V power supply and OPAMPs that can handle the higher voltage or just go for a more conservative version.

bog standard o-11 with Vout= 24V and Amveco TE62062 2x12V 25VA for TX. M3 opamps are AD8065 and gain= x11. the M3 co-designer, Morsel, uses DT990/600ohm.

as far as cranking the PS up to 40V, i would go max 34-35V. you can get a lot more opamp choices by dropping <36V. i would love to compare the differences between PS voltages with higher impedance 'phones, but i have no direct experience and can make no recommendations.

I'm enjoying the DT990/600 with the Woo 3 very much these past few days. Nice tonal balance and plenty of low-end impact.

I should be getting my Hat Peed Thingee in a week or two...I'll give my impression then in my video review...I have the 600 ohm version of dt990.
