Sorry for the slow reply guys. I see there are differing viewpoints as to how to properly form an electrolytic capacitor. I have done some slow rate power cycling, but that didn't really help either. However, I didn't do much, and I'm not sure how much would be required. I basically have hours and cycles on the caps now, and there wasn't any appreciable change in the top registers. Nothing magically changed. I might have to concur with @noromance on this. I have heard profound differences with certain tube burn-in in certain gear though, so I'm fully open to the fact that sound can and does change once properly run in.
Anyways, I added a 3.3uF poly cap (Panasonic WF series) in parallel with the big Mundorf electro just to see what would happen. All the highs came right back. Night and day difference. Almost seemed like the bass is less pronounced too, but I wasn't able to tell yet. After about an hour of listening, my DIY power source for my front end components crapped out. So, it will be a couple weeks before I am back online and can add more impressions. I think this is going to be trial and error based adjustment.
