Hi guys, I have a new-to-me pair of HDI-3600 and would like to turn a great pair of speakers into a super pair of speakers. Having a look at the stock crossovers, lots of room for improvement, I think JBL could have done a better job frankly given the cost of these - no-name electrolytics (par for the course) and no-name film which appear entry level in the HF.
Question is, moving these caps and resistors to Mundorf options leave me with small variances in values.
I am not thinking these variances would make any significant difference, but interested in folks’ opinions. Would these small differences add up, what about the resistors?
Here is what I am looking at - replacement value + originating value for both caps and resistors:
Product+value_________________Original Value_________________Application
MCap Supreme
1.8uF(600V) _ _ ___________________ 1.8uF__________________________HF
MCap Supreme
3.9uF(600V) _______________________ 4uF___________________________HF
MCap EVO
22.0uF(450V)______________________ 24uF__________________________HF
MCap MKP (250V)
15.0uF(250V) ______________________15uF__________________________LF
MCap MKP (250V)
22.0uF(250V)_______________________23uF__________________________LF
MCap EVO
6.8uF(450V) ____________________6.2 & 6.8 uF___________________HF & LF
MCap EVO
15.0uF(450V )_______________________14uF_________________________HF
MR10 Metal-Oxide Film Resistor
2.2Ohm_________________________10W2R4J________________________HF
MR10 Metal-Oxide Film Resistor
3.9 ______________________________10W4R3J________________________HF
MRES20 MResist Supreme Resistor
10Ohm _________________________25W10RJ________________________ HF
Any thoughts or wisdom from experience? Notice I am considering vanilla MKP on LF and Supreme/EVOs on HF..
Thanks!

I think I added some Silver Oil as bypass to the HF since the initial job. Wire replaced with Kimber.
It would make sense to build new boards to better accommodate upgraded parts and improve on the appearances.
I'd also use a screw terminal for pcb mounting.
