When designing a high-fidelity audio amplifier, what are the key factors to consider for minimizing Total Harmonic Distortion (THD) and achieving low Intermodulation Distortion (IMD)?

Hi, I did sort of a compulsive buy of SRH-1840, meanwhile I read some reviews by Sonarworks and @solderdude [LINK] how atrocious distortion (THD?) they have. I decided to give them a listen before returning, and while in less complicated songs they didn't blow me away, I must admit that they...

As part of a study of the effects of non-linear distortions in amplifiers, I came across an aspect that left me a little perplexed. This is the way in which the THD value (and also the IMD and TD+N) of the data collected by the standard measurements is calculated. Measurement of distortions in...

Hi amigos, I discovered this site yesterday... do you want measurements? measures you will have! Here's an impressive list of measures categorized by brands. https://www.soundstagenetwork.com/index.php?option=com_content&view=article&id=16&Itemid=18

Howdy! This question isn't a request or directed to anyone; it's just food for thought. Most of the DACs tested in the past couple of years here all show the output of the APx555's 32-tone test signal in the review, which is fantastic because such a test immediately reveals flaws in the digital...

I just built a power amplifier module based on the Trimodal Power Amplifier by Douglas Self. This is part of building a complete integrated amplifier. I'm now working on the preamplifier, power supply, PHONO preamp, input switching, speaker protection and maybe remote control unit. For those not...

Hi everyone! I've been educating myself around headphone THD measurements, and it's been very helpful to read many interesting posts in this forum, namely to learn how several potential distortion problems are not reflected in THD graphs. However, I would still like to understand why there...

Strong statements like "no distortion is always better" are posted very often and I wanted to know what most people think about that. Is that really a clear, 100% slamdunk statement or there is some gray-area in there and we should be a bit more careful/reserved with the no-distortion 'stick'...

Hello guys, I'm a newbie and a simple consumer and want to understand the practical meaning of the THD value for us. I did some research and found THD values across: DAC - AMP - Headphone and I wonder how to link these. For example: DAC: Pro-Ject DAC Box S: THD 0,005%...

I see people online talking about the hd650's having some legendary <0.05 THD number. What does that mean in practice terms? Sorry its hard to understand what total harmonic distortion means from a listenable stand point. I have a degree in physics, but I am very new to audio. Also what is an...

A recent discussion on the Benchmark's AHB2 discussed the consequences of an amp with measuring THD of -100 vs one with -120 dB. Although unstated, I perceived that the real issue was the audibility spurious sound energy. This got me thinking about how sound levels work across the audio...

Thank you THX! Upon further exploring of their new THX Standard website, there are some really useful measurements for many popular amps and the amp ranking makes sense to me (based on what I've heard/owned)... And many more amps I didn't include, but here are a few compared side by side...
