WVK trolled:

I found the following review for the Hallograph Soundfield Optimizer.
While I am not an acoustics expert, it seems to me that this is one of
those products that are best appreciated while wearing a tinfoil hat.
Any other opinions?

Yep.
With cobweb handwound trannies preferably done by some obscure blind
and deaf Japanese ex-Zero pilot residing in the Hiroshima area,
Polish pre-WW2 paper-in-snake-oil capacitors, NOS 1964 blue LEDS and
burnt-in Kantal 300Bs, it'll sound even better no doubt.
