measurements

I saw someone on Reddit post this morning that they'd gotten this DAC/AMP, which was the first I'd heard of it. Searching Aliexpress lead me to these...

Hey guys, this is actually my first post on this forum so maybe a little introduction is in place. I am an electrical engineer from Finland and I've been in the headphone audio scene for quite some time now, went through a lot of gear and decided to do some measurements of my own. My measurement...

Here we go again, this time measuring a cheap USB-C-with-charging headphone adapter dongle after reviewing the bundled Pixel 3 dongle as well as a Moshi dongle. This is the third installment, and I will follow a similar protocol to my previous reviews. The star of this show is the VIMVIP Type C...

Here we go again, this time measuring a more expensive USB-C headphone adapter dongle. This is my second review, and I will follow a similar protocol to the previous one, with a few small changes. The star of this show is the Moshi USB-C Digital Audio Adapter with Charging. This is an accessory...

So here we go, my first set of measurements using my shiny new QA401. The measurement protocol is a first iteration; comments and feedback are welcome. For another take on Pixel dongles, see these measurements and these ones, both by amirm. One thing that is worth noting is that amirm's...

I just wanted to make a comprehensive post of all measurements, of the ApplePi DAC and Volume-Clocker combo. SNR A-Weighted (XLR): SNR no-weighting (XLR): SINAD (XLR): Dynamic Range A-Weighted (XRL): Dynamic Range no-weighting (XRL): THD+N vs Level (XLR): IMD vs Level (XRL)...

The absence of properly documented measurements from manufacturers was mentioned in the Yggy measurement thread. This is true for cable, most DACs and Amps. To me the main reason for this is that there is no competitive edge in showing those as they would all be the same or would be bad compared...

We'll start with the 12 khz Jtest in a 32k FFT. And what a graph it is. Yes, the horrid looking result is over coax connection. The peak jitter spikes are at – 65 dbFS. There are lots of them not much lower than that, and a wide area is raised by random jitter noise too. The spacing on the...

I've been interested in this amp for a while and now it's near ending. I don't know if it was due to my complaining about the fact that there were none, but they've posted a measurement on the website. I was wondering if anyone could take a look and tell me what you think. I'm not very...

In Another Place, someone asked for advice on whether to use a streaming DAC or a USB DAC to connect to a laptop to provide audio for a study/kitchen. Driven by lossy streaming sources. There was clearly the assumption that the analogue output from PC/laptops/tablets/phones is so bad that it is...

I'm interested in this. Loudspeakers probably add more distortion to the reproduced sound than everything else in the chain, but it's rarely talked about. I have a gut feeling that the infamous subjectivist claim that some systems "measure well but sound bad" may partly be about speakers that...
