The transformers they use were buried underneath the base of Mount Fuji for 10 years prior to being installed, allowing them to project that very organic sound.As a soil scientist, I can advise them of the best place for an even more organic sound. Hell, for those kind of $, they can bury them under my house for as long as they want ;-). I wouldn't even demand accommodation pricing; my pre-amp is just fine.
$100,000 line stage
I know this level of product is not aimed at me. However, im sure it sounds great. The reviewer purchased the unit he reviewed.
