Thanks for the suggestions, good to have some other approaches than the Sony Kimber + TA.I have not tried the EQ setting (on 1AM2) since it does not have an exact 10khz setting but currently, I have 2 things to reduce this peak: dekoni hybrid pads and tube amplification (BA300s and MT-604). The vinyl processing does affect to this peak a little bit too
I've always wanted to try the BA300s and liked the idea of the portability but talked myself out of it as I didn't want to add any more to the already hefy 1Z. I'd always had my mind set on a TA.
