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 go to cap for years.  Used literally dozens of them. Great sounding cap for sure. But, the VH Audio newer Odams are better sounding based on my experience.  More open, improved bass and dynamics. 
@jasbirmandra,
I have replaced the Solens capacitors in my Coincident Frankenstein 300b mono blocks (One cap per channel) with the Jupiter copper foil capacitors. They  are very high quality and very good sounding.

I believe that the Duelund CAST Copper foil is even better sounding. As you well know this is all pure subjectivity and reflective of individual taste.

Thank you for the kind words.

I don't know why some would question the benefit of changing to superior quality capacitors versus price point influenced stock choices

I think it’s a before vs after thing. If you had listened to an amp before an upgrade and then after, the upgrade is obvious. If you get an amp that’s already upgraded, it’s going to sound as good but you won’t be able to appreciate what the caps brought to the table.
