Theta Digital—All Digital, All the Way

Neil Sinclair gave me a tour of Theta’s new multi-channel amp, which keeps the signal exclusively in the digital domain from the S/PDIF inputs to the PWM output stage, the latter said to operate at the super-high frequency of 1MHz. Designed by veteran amp engineer Dave Reich, what is in effect a powerDAC—that’s what it says on the output-stage printed circuit boards—will find its way, I hope, into some two-channel products in due course.
