Positive Feedback never met a tweak they didn't like. As far as I can see, they are the tweakiest of all the audiophile sites.
It's always a hoot the way there are endless veils to be lifted. Upgrade your amp's fuse? Veil lifted. Upgrade your cables? Viel lifted. Put them on risers. Another viel lifted. Add new expensive AC cables, another viel lifted. Plug everything in to a power conditioner. Viels lifted. Put your DAC on footers? Viel lifted.
Your amp? Another veil. Your preamp? More veils.
The lowering of the noise floor, and the ability of the audiophile to hear ever further down that black hole, never ends. Surely at this point they are listening through the very noise floor of the Big Bang.
I think we should get these Golden Eared folks to listen for alien life on other planets.
