...per the linked circuit diagram, the DDDAC is not implemented like the Theta TLC. The DDDAC has the digital receiver (CS8412), an XO Clock (additional crystal oscillator), a 12-stage binary ripple counter (74HC4040, used for the D-type flip-flop?), and no high speed hex inverters. Compare and contrast that to the description offered of the Theta TLC:
"The TLC uses a free running PLL within the CS8412 interface for clock recovery and jitter suppression without a second crystal-based lock (as used by Audio Alchemy, for example). The digital output is re-clocked via a D-type flip-flop with extra 'signal conditioning provided by a high-speed hex inverter—hence the TLC's high output level, clean waveshape and fast risetime."
