Replaced Kimber Kable Hero ICs with Kubala-Sosna

I just replaced Kimber Kable Hero ICs with Kubala-Sosna Emotion ICs. WOW, never thought the difference would be this great. I thought some of my previous music issues were coming from the room but it turns it was the issues of the KK Heros being the issue. Just can't believe the difference the ICs made.

Now I want to know what the KS speaker cables will do
