Well Steve, looks like the Theta does not drop samples after all...

...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."
