BEST HARMLESS/SIGNATURELESS SPEAKERS CAPACITORS.

I may try. You sparked my interest, I found a supplier, he's emailing me availability on mkp 10, there hard to find in USA. Only from what I googled wima may be tipped up/ cleaner from Alumen z. I find the z more on the warm side of the CRM. This may be why you like the wima. The CRM is more neutral than Z for me, I find CMR/Z combine well together. Funny you mentioned tambourines the CMR reproduces that cheap tin metal sound very well and sometimes I use tambourines to judge a cap, tambourine is hard to do correct. Playing drums since a little kid I have problem buying hand hammered Turkish ride cymbals and metal snare drums and also use that to judge caps. Metal snares aren't muddy like a wooden snare. The CMR is good at that but it's not perfect but I find it neutral and fairly true to live music. The Duelund silver bypass goes well with it. One of the best things I found to reproduce that metal crunch sound is a DIY 6 gauge solid core silver wire with neodymium magnets with the RCA center pin punched out and silver wire is connected directly from amp to Preamp with no interference, copper or aluminum braid is return. It does slightly roll of highs but I fix that with a acoustic zen ref 2.

Dear @paulcreed  : Which speakers do you own?

sorry but that " warm " makes no " click " for me at this moment because if the Z was on the warm side of the Wima then why more ears " fatigue " at high SPL with the Z than with the  Wima and why the sibilants disappears with the Wima if like you say is tipped up? Cleaner yes but not exactly tipped up.

I think that next week I will receive what I need for the midrange drivers and we will see what happens.

Main speakers are older Joseph audio perspective not current perspective 2. I have not altered those yet and don't know if I ever will. The speakers I have been playing with caps are LSA Statements floorstanders. LSA had 3 versions standard, signature and statement, the statement has ribbon tweeters. I've owned these LSA's for 15 or more years and always enjoyed them. After adding new caps they are now much better speakers. I also have some Usher tiny dancer and some GR Research hot rodded monitors which are the speakers that got me interested in changing caps. I've not had any fatiguing issues with Z's even with ribbon tweeter.
