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

R, you continue to claim all boutique caps colored and distorted. W/K/V no coloration, only accurate. So, everyone using colored boutique caps has defective equipment which requires colored, distorted boutique caps to sound natural. So, now we've gone from best caps to best equipment which you seem to have exclusive possession of here. So, we mere mortals with defective equipment can't appreciate the accuracy of your chosen cap.
There can be no dialogue with you,  you have the best ears, equipment and caps. Be happy in your delusion, I'm ok with you believing that. Why can't you let us be happy in our sad delusion?  This thread is about why and what we like our chosen caps, not making claims of a single best cap. Your posts rightfully belong in thread attempting to offer proof of an objectively best cap. See how many respond to that, should be a real fun thread.

“but good to use as a bypass cap.”

Any value in bypassing an ODAM with a CuTF? I have a couple of CuTFs lying around.
Reducing the value not a good idea ,when engineered the UF needs to be the same in s amp,preamp, in a loudspeaker 
maximum different change under3%
bypass caps for small  values very common to use .01 uf 
the vh audio Cu Copper Teflon are excellent as PauL mentioned
the VH CU is superior to the Odam  and can be used values .01 
are typically used in the HF range,but can put on a midrange also.

I would not use a bypass cap in a crossover. Don’t think they sound right in this application. Makes the sound sort of nervous. One great cap is better. Bypass caps are great in power supplies and SOMETIMES in coupling and output positions. It depends on the combo of caps used. 

Odam and Cutf sound wonderful together in electronics.  The .01uf Cutf combined with a .22-3 uf Odam works great.  You get a little more air and detail.  
I personally prefer the sound of Odam over the Cutf used alone. The Cutf is just too lively and exposing for  my tastes. This is a personal preference thing for me however.
