ARP 4075 Filter Mod - Before and After

I have recently been working on my Arp Odyssey 2813 restoration project. While recapping the synthesizer, I decided to go ahead and perform the 4075 modification while the filter board was disconnected.
Apparently ARP incorrectly calculated some resistor sizes during design which caused the 4075 filter to not reach the optimum frequency cutoff range. I went ahead and recorded some before and after clips to see if there is a noticeable difference. I can't hear a difference... maybe you can?

違いがなかなか分かりませんでした。
滑らかに変化するようになったんでしょうか？

私も違いが分かりません。私にも同じように聞こえます。高レゾナンスだと少し違うかも？
