I can vouch for my Artesania Esoteric rack.
And it looks fantastic. Really completes my system, and every component is isolated from the frame. They don't use shelves, instead wee shock absorbing pucks made from non conductive material support the components. There's no point grounding my rack, as it doesn't conduct anything from the frame into the components.
Interesting that folk speaking against well-designed and built racks are so passionate about something they know nothing about. Very curious...what drives such people? Determination to never learn anything?
I have never heard of someone with a decent rack then casting it aside as a failed experiment. They don't seem to come up second hand.
