Thanks for the link. The current GLM 4.1 released a few weeks ago still targets a flattish bass, and Genelec has caved in a little by allowing a slight bass-tilt as well as boosting a few PEQ slightly (depending on monitor/subwoofer capability) compared to GLM 4.0.
I'm using the RME ADI-2 DAC FS and the dynamic loudness feature for added bass at lower listening levels. The DAC even has tone control knobs for quick adjustments.
That is good to know with new GLM. Probably the dac/headphone amp/eq I would buy if I ever buy a dac/headphone amp/eq. It needs an accompanying hd800s though.
