VAC owners, sound off

Tholt, what is the power supply sitting on? The material it sits on will definitely make a big difference in the sound. I've tried MDF, solid oak, solid cherry, granite, butcher block, and the best is the Mapleshade solid maple platform with brass spikes. The second best was the MDF. Also, I think the VAC standard preamp inverts phase so you will need to reverse the connections at your speakers.

Tholt, I tried spikes between the PS and the platform and didn't like the results. Currently it sits on the Mapleshade platform on its own feet. The Mapleshade is spiked to the bottom shelf of a Polycrystal rack. I don't like the Polycrsytal rack BTW.

The butcher block should thin out the mids and give you better top end extension. The bass may be a bit unpredictable. Have fun experimenting.

Tholt, you will be in for a pleasant surprise now, after you compensate for the phase and provide better support for the PS. You'll be jamming tonight!

So in a general question, what's the deal with inversing polarity? Why do some manufacturers do it and not others? What's the advantage?

It's a simpler/shorter circuit with only one gain stage that is cost effective for the price/perf ratio. My Renaissance does not invert but it costs more as well.
