@lous I am solidly in the Vandersteen camp but i think your knowledge of what they sound like is dated . Lets start with your assertion of electrolytic in the tweeter filter. They are NOT nor have never been in the audio signal path. The audio path is bypassed film. The electrolytic caps as used in Vandersteen speakers are super important parts as they form a Zobel network or anti-tanking or a resonance peak filter to flatten out the impedance curve. When you bypassed those you honked up a great filter design. RV and i go back to 1981, i think i understand his filter design. I would also encourage you to hear newer Vandersteen designs or updates. My best to you ! enjoy the music. RV picks up the phone at the factory.
