Thanks a lot Sir Joey. I found out that my Aikido 6dj8 is best suited for my modded LSA1 while the Aikido ecc82/ecc81, whose family sounds leaner than 6dj8's partners well with my KEF Q90 FS which has a big, robust bass.
After 200 hours of running-in my Aikido 6dj8 with the Mundorf Silver/Oil, I finally got to listen: it seems there is added depth (as compared when the Mundorf were first installed) and voices sound clearer and fuller. The highs are already sparkling and very clean. The bass seems to start being punchy but I felt not punchy enough. I expect it to become deeper and fuller in the next 100 hours.
In my limited experience it seems that the Mundorf Supremes are harder to break-in and the details + sparkle will come last while the Silver/Oil will have the full rounded bass last.
I highly recommend this to owners of Aikido pre, specially to ones built by Ka Jojo. At first, it appears that there is another unnecessary upgrade expense that's obviously not cheap, at least for me, who always aspire for better gears but unfortunately isn't lucky enough to be rich. This might actually be cheaper than experimenting with buying other gears, accessories or sets of speakers, only to sell them later at a loss. Sulit to the last centavo, eka nga!
I intend to enjoy listening to my disc collection all over again with my JojoD gears that deserve to be truly heirloom items.
