Sparkos Labs high end audio components and DIY audio modifications for Hi Fi Audio

Where High End Audio Components and Gear Live.


Sparkos Labs specializes in high end audio components, design, and gear.  It's the culmination of a lifetime passion for audio, and electronic design and engineering.  From its humble beginnings back in the late 1900's in the loft of the family shed all the way up to the present day, it's the birthing ground for all of the fodder that is constantly churning in my head.  Thanks for stopping by.  Enjoy your stay.
