I remember - had CAL-15 cd player for many years.
It was an excellent sounding player - resolving, with deep bass and non-fatuquing sound.
I upgraded it to Sony 5400ES super audio player and cannot state that Sony sounded better with red book CDs.
Who remembers California Audio Labs?
CAL certainly made a big splash in the early days of digital. I owned an Icon for a number of years and enjoyed it so much that when Power Boss was announced I had my Icon upgraded to a Power Boss. And then California Audio Labs was bought out and disappeared. Not overnight but from the perspective of time, it seems so. Anyone else wonder what could have been the company’s future had their trajectory followed a different path?
