The Sonic Farm booth was filled with gorgeous gear - we have videos of their studio range, and also the Tantra Bass (pre)amp, which was designed together with Michael Arnopol Soundworks (MAS).
The bass amp was feeding a MAS cabinet, and the combination was really impressive - due in no small part to some pretty trick design principles in play in the cab construction (manipulated vortex waveguide, anyone?)
Fortunately Micheal Arnopol himself was on hand to make sense of it all.
