Bright or harsh could be at several different frequencies. I have Klark-Teknik 31 band equalizer in my system. I think it is DN360 or DN370. It is a studio equalizer. It sounds amazing. If you do not have xlr, you can get some nice xlr to rca at Moon Audio.
You can download Spectroid app on your phone and quickly see where the nasty frequencies are. Good luck.


I have a Schiit LOKIUS 6-band EQ, signal coming from a LAIV Harmony DAC then out to an Emotiva pre-amp to an Advance Paris power amp. You can flip a single switch and turn the Schiit’s EQ off to A/B test your results. I’ve found my Buchardt E50s need just a touch of boost in the BBC dip range.
