Default AK4499EQ - Best DAC ever

In January 2019 comes the new DAC AK4499EQ from AKM. If you can believe the given values, then this DAC is probably the best that ever existed. Since we can look forward to even better audio analyzers. From the site: It achieves the world’s highest class of low THD+N and high S/N. Samples will be available in January, 2019, and Mass Production starts from May, 2019.


AK4499EQ: THD+N -124dB
AK4497EQ (predecessor): THD+N -116dB


AKM releases their latest flagship audio DAC, the VERITA AK4499, achieving THD+N: -124dB and S/N: 140dB | News | AKM - Asahi Kasei Microdevices

Well, at least the best measuring audio DAC...

There's already a thread on it, and the the title of this post is misspelled.

Can it be used in NOS mode?

Back in the early 2000s, TI intro'd the PCM1792 with 132db s/n (mono) ... and, like the new AKM, the TI is current output.
So, the 16 years or so between the monolithic designs has not improved specs all that much.
Ahh .... the designers must spent time with "careful" voicing and subjective tests ... yeah, that's it!!
Funny, tho ... neither TI nor Cirrus/Crystal have followed up -- over the same time frame -- with serious replacements: the 1792 and CS4398 are still in production.
Only AKM and ESS seem to be "re-inventing" their orig. SD designs from over a decade ago.

Note: The specs are claimed my manuf. per their datasheet.

Unlike the new AKM, the TI chip had a real current output (i.e. high impedance).

CS43198 is a pretty good improvement over CS4398, especially given the power consumption and features.

TI probably doesn't feel the need to compete in this inaudible spec war.

The THD of the newer parts has improved, too. Especially if you compare the AKM DACs from the time PCM1792 was released to now. They may not have made huge progress relative to PCM1792, but they have come a pretty long way from their own products of the day.

Surely, you recognize it is difficult to squeeze out the last bit of performance. It's not easy to reach 23-bit performance.

Does it really matter? Current outputs are only useful for this spec war. Outside of the audiophile market (and maybe a few test and measurement folks), no one will buy a current output audio DAC.

Does to me. Can't speak for anyone else though.

How so? I find current outputs useful as it allows filtering prior to any active stage and adding the filter does produce subjective improvement (not only to my ears). Trying to add a passive filter to an ESS or AKM resistor array DAC does look rather fraught to me.
