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

Good for you! Why would you change the values? Keep them as now! Higher voltage ok, no to impedance change.
I am not changing the value currently they have 0.33 uf was asking which brand to go with as there are 18 caps to change
I like Vcap Odam much more than Miflex . Just pulled out Miflex and replaced with Odam in my amp. Much better after break in. Everything improved from bass to highs.  More depth, more inner detail…..you get it. 
Miflex are forward sounding and not as smooth and detailed as Odams. Odams are even better sounding than Jupiter copper in my experience, but I shared this already.
