Metrum comes out with a new flagship NOS (Non-Oversampling) R2R DAC, using its own in-house manufactured/designed DAC chips in R2R configuration (I believe)...should be very interesting to hear this one given the success that Metrum have had with well respected reviewers like Martin Colloms/HiFi Critic. Cost is roughly $5K...refreshing in a world of steep 5 and even 6-digit reference digital systems.
“Each DAC cluster processes a portion of the data in the most linear region of the DAC chips. The result of this process is an extremely high linearity, right down to -140 dB, which gives the Pavane a realistic 24 bit dynamic range."
