This week Danny sent me a different capacitor to try in my Super V tweeter circuit. The new cap is a Russian paper and oil type cap bypassed with a Sonicap Platinum. The idea was to put it into the circuit of one speaker and compare the sound of the two speakers, one stock and one modified with the new caps. To be honest I was having a hard time hearing any difference when switching between them due to the time involved to switch cabling to play the other speaker.
So I fixed up a relay switcher that I can control at my listening position. The simple push of a button changes which cap is in the circuit. Now I can hear the difference, it's more noticeable on some material than other. The paper oil cap takes the edge off of some live recordings which were way to hot and irritating. It also helps with recordings with bad "zzzzz" on every vocals "s" sounds. On some material I hear no difference at all. Today I'm going to play a track of pink noise, it should be very noticeable there.
