What it looks like with Loki+: Spoiler: YH2 philmod8 / closed mod and Loki+ Scatter shot of EQ. Not tested. Just interesting. Number 2 and 5 look nice. Previous tests of boosting bass with EQ were not good. Edit: no.2 is good. Max minus 2kHz is correct (probably source of fatigue yesterday, Grado-heat). YH2 modded and EQed rocks. Anyone welcome to borrow if you have a Loki+. But I'd recommend just buying a cheap YH-2 and try modding yourself. Shipping back and forth for loan is nearly the cost of the headphone itself. Edit2: Spoiler: YH2 vs Emu Love both these headphones. The Emu Ive increased eq slightly since, 'twas a very little dry and bright. (2k to 8o'clock, and 8k to 8o'clock), maybe due to new tube being less warm(?).
