Hi @Reddasher! Welcome to ASR. The modi3 is as good as it gets DAC-wise. Sound quality doesn't get better.

Hi @Håkan Lindgren! Welcome to ASR. The G5 has three Gain settings: Low, Medium, and High. Higher gain = higher maximum volume, but also more hiss. This is shown here: (Blue=Low, Green=Medium, Red=High) As a rule of thumb, always use the lowest gain that still allows you to reach your...

You mean a physical volume knob? You could always add a USB volume knob to your computer and that plus the PO100 would serve the same purpose.

Via the default OS volume controls in iOS, macOS, Windows and Linux. Doing so will send UAC2 Hardware volume commands to the PO100 which then attenuates the signal using its Xmos processor.

Just FYI, the SMSL PO100 2024 supports SPDIF output with volume control and costs a fraction of any of these.

I was not able to find a proper assessment of a Klipsch WDST speaker. However, these kinds of designs tend to have wildly inconsistent directivity patterns due to interference: One can use acoustic lenses to minimize crosstalk and homogenize the directivity as best as possible, but Klipsch...

Don't confuse uncontrolled impressions with fact. Either the video settings changed between cables, the cables have image processing built in, or you fell for simple confirmation bias. It is not physically possible for two simple cables to produce different images with identical image settings...

That's where honest and sincere communication comes into play :) For example, you could tell them that, even after you've adjusted your system based on what you heard during the test, if at any point the noise becomes too much, they can reach out and you'll readjust your system. Communicate...

I'm a do it once, do it right advocate. I'd prepare some test tones, then ask them kindly to, at a time least bothersome to them, be able to listen to them from their apartment. It's to reduce noise disturbance, which they can surely get behind. You can use something like Chrome Remote...

That, or you can stream your music to the WAP via UPnP/DLNA. Yes. It depends. On macOS, the default OS volume control only works if your USB->SPDIF converter supports UAC2 Hardware volume control. On Windows, the default OS volume control will work with all converters, unless you use ASIO or...

Better in that it's asynchronous so the DAC can do its own clocking. Worse in that it's electrically conductive so can invite ground loops and USB noise interference. Just FYI, neither gold nor aluminium nor any other metal serves any purpose for optical signal transmission. You can know...

I mean...in the first place a miniDSP would likely achieve better results for a fraction. Chasing a feature-rich, all-analog signal chain sure is impressive from an engineering standpoint - but still a fool's errand.

Same FFT size with higher sample rate means larger FFT bins means larger curtain around the fundamental. Increase the FFT size in line with the sample rate and you keep bin size equal, resulting in an equally sized curtain. Or use Rectangular window with periodic matched signals to get rid of...

To EQ a headphone to Harman, you need GRAS or 5128 measurements in either raw form, or compensated to a known reference. Your two graphs are neither of these things, so are not useful for Harman correction.

DLBC is basically an automated version of Multi Sub Optimizer, whose advantages cannot be captured in a single-point sweep measurement as seen above. Its entire purpose is to minimize nulls across a wide listening area, so measurements would have to be performed across said area to show the effect.

Correct.

You have two options: Either do ATV->HDMI->TV->HDMI(ARC)->DAC, or ATV->HDMI->HDMI Extractor (Link)->SPDIF->DAC, plus Extractor->HDMI->TV. In both cases, you can display album art on your TV. The first option routes audio through the TV itself while the second one bypasses the TV and sends...

The WiiM App Crossover setting applies a low-pass filter to the Sub output and a corresponding high-pass filter to the Speaker output. I would set the KEF to LFE and let the WiiM handle Crossover duties.
