DJ, further to the reply above, it took me one more day. Last evening I added the 2 Pannys 1200uf. In addition, given what you mentioned, and that the physical proximity may indicate a related function, I added the Elna SII 470uF. This is in the slot next to the Pannys.
Then I sat down to read, with the music on. It was not yet the time for evaluation, of course. OTOH, the rest of the equipment was already warm from playing via the CDP for hours. So, I figured I would endure the early stages of the change. Any such, would have to be from the Musiland.
I expected it to sound bad'ish. It did. For about 2 hours.
Then, a remarkable change in character began to happen into the 3rd hour. I dropped the book and fully listened for an extra 3 hours. The changes stopped being fast paced into the 4th hour. I am absolutely sure that things will keep changing for a long while, at a slower rate, mainly because of the Elna.
As to how it sounded, the best way I can say it is this. Each aspect of what the new opamps had improved before, was multipied, say, 3x.
I am guessing, but I suspect that with the new caps helping on the power supply side, the LME49990 opamps are being better able to express their attributes.
Things may still go south as they mature. However, one major surprise came when I decided to compare against the CDP, at the end of the session. I sure hope future changes in maturity don't spoil what I heard then.
