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

My favorite capacitor is the Duelund CAST tinned copper version.  They are available at HiFi Collective in the U.K.   They ship fast however.  Next is the Odam and then Jupiter copper foils.

I cannot vote. My ODAMs will only arrive on Thursday and I heard Jupiter’s so long ago I cannot recall what they sound like.

If you really are in a bind to choose, why not get both? Pick one for an output cap and the other for interstage. Maybe your subconscious is trying to tell you something? 😆🤣
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.
