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

The Odams are far better! Nice job with the Cutf upgrade! Just wait till they break in fully! 
Thanks for your advice grannyring  - 4 ODAMs on their way. I’m not even going to put the cover back on. The ODAMs will be going in the minute they arrive. 

"I am blown away by the improvement given the mediocre 3.0uF signal caps are still in place. 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."
Congratulations @pauly,  happy for you. 
I don't know  why some would question the benefit of changing to superior quality capacitors versus price point influenced stock choices.
