Those are simulations. You have to measure yourself to see the "after" results. See my review of here: https://www.audiosciencereview.com/forum/index.php?threads/audyssey-room-eq-review.12746/ See what I labeled on the right. This is actual results: With higher level of filtering to see...

??? No DACs were tested as originally claimed.

It could be in the source or the device itself or combination. On #2, it is not possible to only send audio over HDMI. The "Audio Only" HDMI ports send out black video signal. Video is the master and audio is the slave and it must always be there.

The owner told me it has different tuning. This is all I know.

Updated the review with "Silver" addition and higher price for that ($22 on Amazon). Forgot to add the Specs. So here they are:

A NuVero 60 is being measured as I type this. :) If all goes well, I should have the review out in the next couple of days.

Again as I noted very early in the thread, controlled blind testing by Meridian/MQA folks showed audibility of different DAC filters. This was peer reviewed and published at AES.

This is a review, listening tests, EQ and detailed measurements of the KZ Castor Silver IEMs with configuration Harman frequency response. It was kindly drop shipped to me by a member and costs US $22. The Castor is attractive while looking reserved and was comfortable to wear. It comes with...

A and B are always the same.

Such extraction if it exists, would have to abide by rules of HDCP copy protection for HDMI which forces output to be 16 bits and 48 kHz at best. These other devices ignore that license agreement and pass through the bits as is.

Yes.

In HDMI, the audio clock is derived from video. Video signals are immune to jitter as the pixel position is fixed (was an issue with CRT terminals). Audio was an afterthought and added in spare scan areas of video. The extracted samples are running with intrinsic jitter of the video clock...

I think that was his tactic to say Erin is better than me because he took his video down and I did not do the same with my review. Now that his scheme didn't work, he is going back to complaining about him.

Power amplifiers are the least reliable components in audio systems due to high voltages, power and heat involved. I have repaired hundreds of class AB amplifiers so they absolutely fail. There should be no automatic assumption that they are better in reliability. They are however much easier...

Usually to extract audio out of HDMI to use with typical 2-channel system that lacks it. This one is even more niche in that it allows DSD stream over HDMI, e.g. out of an SACD player, to be extracted and transported over IIS to many DACs that support it.
