I'm sure it's a great sounding system (if I had the room and funds, I'd probably own something like it) but, sorry, I just can't get past the pretentiousness of the sound installation/shrine to music angle that Devon is using to promote his wares. He could have hired some other space in central London to show his system but, of course, that wouldn't have had the artsy-craftsy appeal of the Lisson Gallery.
And what were Blue Note thinking when they allowed those master tapes to be played? Notwithstanding the wear/damage that could result, it's a pointless exercise due to the very nature (uniqueness) of the medium!
