No, I don't, and I wouldn't given an unlimited budget either. I think these "tweaks" are antithetical to HiFi. The entire point of a high fidelity gain stage is to build a circuit as revealing of the input signal as possible while revealing nothing in the source of power. I consider these kinds of tweaks revealing only the weakness of the gear. It takes no skill or cost to build gear sensitive to anything coming through the mains. It takes skill and money to build gear that is indifferent to it.
