Hi,
I've only had the Vali for a couple of days, so I'll defer making comments about its sound quality until later, but the microphonics sure are annoying.
My tubes were stuck down to their pads when I opened the case to have a look, but they ring badly whenever I turn the amp on, touch the volume control, plug in a headphone, etc.
None of this is news to readers of this thread, but I found a way to make the ringing settle down much faster than it was settling previously:
These Blu-Tack blankets are attached to the glass - not touching anything else - and not touching the leads.
This has done a lot to dampen the microphonics, but it's not a complete cure - it only makes the ringing come to a stop more quickly.

The material [Blu-Tack] will burn under extreme heat, with a flash point of 93° C / 200° F, at which point it will release quantities of carbon dioxide and monoxide, water vapour, oxides of nitrogen and toxic fumes.
