Quick results test two, Saturday - It appears he is not crazy after all. The Caddocks facing the other direction (away from LM3886) appear brighter, the stage is a tad wider and separation is improved. What was most noticeable was more of the metalic element in the guitar strings. I heard more ssss-eness in the voice but not enough to call it distortion. Writing to front wins.

I wonder if the big boys sucker the newest, youngest employee into doing this kind of tinkering ??

C30 next....

Test #3 - C30 Euro KP1830 1nf. First run, no burn-in - a little cleaner, possible more punch to the kick drum. The combination of these and the Caddocks in test #2 adds to the 3D element of the stage - not dramatic but noticeable.

Going to run a pass or two of the IsoTek and will report again in about an hour.

A suggestion... since you're going to run the isotek mount also as much new caps as you can, so you do burn-in for all in one time.

It's bipolar, no problem.

Obviously it has a side that sound better.

I use the side with the KP1834 marking the opposite side of LM3886.

Now I'm going to dance Salsa.

See you later.

The outer foil of such a rolled film cap is usually the one which has a marking and should go to the lower impedance point, in this case the LM3886 output. At least from the technical POV.

O.K. this on is more difficult. I did burn-in multiple caps at the same time but replaced the not yet tested with the former/stock pieces. Zeroing in on C30 (post 513) was at once very clean and at the same time more dispersed. Some trumpet licks that were mostly centered now appear pushed to the right. I did a double swap to confirm and would have to say this is the least effective and benificial of todays swaps. The fret noises sound more natural in one orientation with good mids and bass but the stage is too messed up.

Going to stop for the day but will continue in the morning.

Cheers !
