Capacitor


Dear friends I am interested to upgrade my caps in the tube preamp from Audio theta tin foil 3uf200VDC to Miflex1uf 240VDC copper foil what are your thoughts will reducing the value to 1uf affect the bass and frequency response or should I go with a higher value than 3uf

Up to now I perceived Odam as go to capacitor for electronics and where physical space at a premium. A lower priced and smaller size cap that beats higher priced and larger size caps? I'll be replacing the modwright caps in my phono stage with odams, perfect place to try as space at a premium.
I can only tell you my experience with many boutique caps has all been good, just different sonic signatures, none bad. If the odam is as good as stated, should be go to cap for nearly all circumstances. Although I've not heard Duelund Cast in my system, would still be my pick with no space or cost considerations.
Odams are great in speakers. Be aware of break in time as it is real with these Odams.  They take some 75-100 hours to fill in and open up.  A tad constipated sounding on first few hours.  After just 30 hours much better.  
They are directional so pay attention to outer foil. 
Dear @jasbirnandra and friends : Next are statements made it in this thread that similar to other statements made it in several threads ( including a thread I posted almost two years ago. ) on the capacitor issue: :

" Milflex are good, but not great. The VH Audio Odams sound better in every sonic way..."

"" more holographic image I suggest two cap brands.
- VH Audio Odams
- Duelund CAST CuSn - tinned copper version ""

""" New pre-amps, which incidentally will have the same or similar mediocre capacitors we are replacing in the Canary pre amps; meaning we’ll be back at square one looking to upgrade capacitors in our new pre amps. """

"""" the Duelund CAST Cu(Sn). This is the best sounding capacitor ever produced in my opinion. """"


""""" As I’ve said before in regard to them, they are worth every single penny charged for them. A superb sounding product """""

"""""" was immediately heard as an improvement ( Even though quite honestly the sound was very good with the stock Solens). Sound quality continued to improve as the CAST accumulated hours of break-in. """"""

""""""" It sounds like angels are in my room singing to me. Strings just hang in the air and the low level detail is almost overwhelming. """""""

"""""""" More open, improved bass and dynamics. """"""""

""""""""" And how are they on tonal balance, accentuate, soften or change any part of frequency spectrum? """""""""


With all respect to all of you. From where comes that differences in capacitor sounds when a good designed capacitor can’t develops/generate a sound by it self and certainly can’t improve the quality performance of good electronics designs or speaker crossovers.

When I posted my capacitor thread looking for help many of you posted about and I really appreciated your posts.

Well in those times I was not aware of the next link on capacitors,things are that I just found out today and could be truly interesting for some of us ( me included. ) this spot on capacitor article:

@jasbirnandra in the next link the last page of my thread. Please take your important time to read all that page that as the linked article is self explained:


https://forum.audiogon.com/discussions/best-harmless-signatureless-speakers-capacitors?page=4


in that thread I posted several links with measures, proved facts and true evidences on the whole capacitor main issue. One of those links was this one ( you need to paste all the link: the black/blue  that start at " chrome-extension........ ):


chrome-extension://efaidnbmnnnibpcajpcglclefindmkaj/viewer.html?pdfurl=https%3A%2F%2Fwww.vishay.com%2Fdocs%2F26033%2Fgentechinfofilm.pdf&clen=595770&chunk=true

Certainly it’s not at random that Wima, Kemet and Vishay are the world industry capacitor standard.
You can name any kind of industry: medical instruments, military, aerospace, automotive and almost everywhere but " high-end " audio and only are used those caps in specific areas but as me in the past no one ask why are used " there " and not the " boutique/sneak oil " " caps ".

I invested thousands of dollars learning through the boutique ( almost coming from every manufacturer ) caps and finally I learned through the standar caps that are the ones I use in electronics and crossovers.

Of course because my main MUSIC/sound target in my room/audio system is to be truer to the recording truer with what the recording microphones pick-up in its MUSIC source near field position.
This means that I try to mimic what I listen in a live event seated at near field position as the microphones are, yes I’m really far away to achieve it.


Regards and enjoy the MUSIC NOT DISTORTIONS,

Well hello again. Yes sir, try Wima on your own folks and see they are flat sounding and mediocre at best. Others have reviewed the Wima and found the same. Best to learn for yourself fellow Agoners. They are not expensive to try.
I believe @rauliruegas is sincere and has good intentions but he consistently has a ’know it all’ condescending manner toward other posters on this forum. I believe that he is convinced he has more exposure/experience/involvement/understanding with live music up close than ’any'  others here, so he must be the authority or arbiter of what’s correct.

He cited a few of my comments above in reference to Duelund CAST Copper foil capacitors. Well I stand by every word that I wrote. I judge strictly on what I’ve actually heard, no apologies. If he finds the Wima the best example of an audio capacitor, good for him. Others can if they are interested or curious listen to them and judge accordingly. I’m confident in my assessment of the CAST and as always YMMV.
