DAC that re-clocks for under $1000?

Does these DACs really "re-clock". I was under the impression they were jitter immune/rejecting but do not truly reclock.

You are correct in that the majority do not "re-clock", however, the Benchmark DAC is truly "asynchronous" - so it is completely ignoring the input clock and unlike most other designs it is not trying to keep in time with the input clock.

Surprisingly, I still do not think any others than BEnchmark have been identified and confirmed?

i have confirmation from PS audio tech support that their digital link III does re-clock the incoming signal. Documentation for the Music Hall 25.2 DAC specifically claims it re-clocks the signal. I am not sure what "asynchronous" means - if the Benchmark ignores the input clock, it has to apply some kind of clocking to the signal before it sends it out to the pre amp, right? Can we say then that it "re-clocks?"

As far as I remember at 50GHz most of samples are redundant. This frequency is not real (1 million times oversampling) and is based on statistical manipulations(finding exact spot for the output sample).

They also mention updating output DAC at only 110kHz. Most of DAC chips have higher THD at 192kHz than 110kHz.

Asynchronous upsampling never brings exact oversampling ratios. If specification says 4x,8x,128x etc. then it is not asynchronous upsampling converter but rather oversampling one based on PLL (phase lock loop).
