I thought I would throw this out there. I am the head of the Las Vegas Audiophile Society and we just had a meeting at my house this past Saturday. It was great, a great group of guys and it surprised the hell out of me what the star of the show was.
I had been using a small, cheap Schumann resonator powered by my BatCap batteries. The resonator made a difference but not a huge difference. I also use iFi Audio DC iPurifiers to clean up power from the batteries (Yes, batteries can make noise, from chemical reaction, etc.) on my LDR passive preamp and my Temple Audio Bantam Gold 12V Tripath amp. For the meeting I used my tube amplifier so I wasn’t using my 12 V tripath amplifier, and so the DC purifier for that wasn’t being used.
I decided what the heck, and I put the DC purifier on the Schumann resonator. Wow! What a difference! Definitely noticeable when I turn it on and turn it off. Bass is fuller and more easy, a more “holographic” image, a better feel overall, all the good stuff.
At the meeting I talked about the resonator and I switched it on and off, and every person heard a definite improvement with it on. Amazing since a super good iFi purifier wall wart power supply and the resonator itself is less than $100. I ordered a pair and that made it even better.
