kicking off this thread with an example of a budget upgrade on a pair of speakers with the hope that people follow along with more examples of high value upgrade part pairings. Attached are photos of the upgrade and the xo diagram with original parts list.
The speakers are monitor audio silver 100 7g's. The upgraded parts list for one speaker:
1xJantzen cross cap on woofer
1xJantzen superes resistor on woofer
2x Clarity cap CSA on tweeter
2x Miflex kfpm-01 0.022uf as bypasses on tweeter.
2x Ohmite audio gold 5w resistors on tweeter.
2x original polypropylene caps originally in series with tweeter moved to c4 position with 1x clarity cap px .82uf added to make up value.
All larger caps and all resistors were matched and the total parts cost was around £140 for the pair. I lived with the speakers without bypasses for a while but felt I was lacking some high end detail. This was completely solved with the Miflex bypasses.
Timing was improved and I started to hear more micro detail as well as sometimes the breath of artists is now coming though. The instrument and vocal placement improved with what feels like a more spacious layering. The only negative of the bypasses is If I play poorly recorded music now it's more apparent. In my opinion this is because the speakers is far more resolving now.
I look forward to seeing all of the great upgrades we all like to do to our speakers as well as opinions on components!

Sure it's just my opinion so far. I haven't noticed any bad effects but this is the first time I've used bypasses so I'm open to everyone's opinion on the matter. I did see some people like the cde 940c and 942c as bypasses.
I rebuilt the whole board using all new components & spaced all the new air cored inductors (all with thicker gauge wire) further apart in my Monitor Audio Bronze BX2 rebuild/modification..
