I'm speculating, but I'd say most of the frequent visitors to this forum look at measurements more for signs of excellence in engineering than from the perspective of audibility. That said, a while back forum member @flipflop compiled a bunch of audibility research into a post titled...

Here's my Monster Power AVS 2000 and PowerCenter HTS 5000 "with clean power stage four filtering". Recently I pulled out my Rigol 1054Z and a differential voltage probe to measure the AC mains both at the wall and after passing through the Monster stuff. The wave forms going in and coming...

I used @MZKM's data to create a stacked bar chart with the speakers sorted by measured sensitivity. When the measured sensitivity was the same as or higher than the claimed value I didn't bother to display it.

Have a look at this thread for a good discussion of the differences between ASIO and WASAPI: https://www.audiosciencereview.com/forum/index.php?threads/kernel-streaming-asio-wasapi-and-music-players-foobar-jriver.7412/#post-171098

Have you considered using a traditional preamp rather than the Mackie Big Knob? The Schiit Freya S tested very well and it's on Amir's recommended list. The Freya may cost more than the Big Knob, but it will give you a lot more flexibility. You get the choice of passive or active and you get the...

I believe the DAC chip in the Topping D10 is actually an ESS9018K2M. Amir's measurements of the D10 do not show the ESS hump:

Math does allow us to quantify the information content of a signal. Claude Shannon showed us how by giving us a formula for entropy. I thought I would try using Shannon's formula to calculate the entropy of a dithered file and compare it to a non-dithered version of the same signal. I made two...

Funny. Amir actually reviewed a similar wood "ground box" here. Maybe not surprisingly--it actually increased noise because the ground wire connected to it acted like an antenna.

From the manual:

Does that mean the AP feeds the Yamaha's analog line in with a voltage in of 0.1587 V? I'm assuming that V out is given by And that you can solve for V in like so Do I have that right?

Yes, the knob does adjust the volume.

Topping D10. It's a DAC, but you can also use it as a USB to S/PDIF or TOSLINK interface. $89 US. I have 2 and they've been rock solid.

64-bit sample depth? What are you recording over there, gravitational waves? ;) If I did the math right 64 bits should get you to -385 dB or 5.42e-18 %. Sprinkle in some dither and and you're almost there.

Sure. I'm not an expert, but I can share what worked for me on the x64 version of 18.04.4 LTS. First if you don't already have wine installed then install wine-stable 4.0.3 from Ubuntu's app store. If Wine is installed and you have downloaded and extracted the DeltaWave installer, then you...

I know there are quite a few Linux users on ASR so I thought I'd share that I was able to run @pkane's DeltaWave on Ubuntu using Wine. I didn't do much compatibility testing, but I was able to compare a couple of wav files without issue. DeltaWave 1.0.50 Ubuntu 18.04.4 LTS Wine 4.0.3 (64-bit...
