On the basis of it has a valve, it looks good, it cost £160 delivered, it is just a headphone amp and the power output specs suggest it will easily drive my various headphones, I bought the Vali 3.
So far, so good. It sounds as good as the Musical Fidelity X-CanV8 and heavily modded X-CanV2 it replaces. Maybe hi-hats are not quite as clear and it does not have quite the dynamic drive of the X-Cans, but mid-range is improved. I can make out lyrics I could not before.

There is also no electrical noise leaking through to the headphones any more. The X-Cans both produced a slight background hiss, which has gone. Whether that noise affected overall SQ, the hiss was so slight, I cannot say, but it is nice to know it has gone. It drives the DT-990 Pro 250 ohms with no issue at all and I like the gain adjustment, to refine volume control.
Overall, highly recommended and I have not even started to change the tube and try others, something I could not do with the X-Cans.
