distortion

Introduction On August 15, 2025, at the 19th Shenzhen International Audio Show held in Shenzhen, China, Moondrop introduced two new planar magnetic headphones. Moondrop is a brand widely known for its well-tuned, neutural sounding IEMs with cartoon child figures printed on the package of...

I'm still deciding whether I should buy speakers or not. The options I have are the D3V's and the LP UNF's. But looking at their distortion measurements, it really throws me off. I don't really know how to read distortion measurements, but with my limited knowledge in this topic, this looks...

Hello everyone! I have a question about the EQ settings in REW, specifically LP filters and how they affect the distortion measurement: When I apply a low pass filter in the EQ settings and "measure with these filters" the distortion somewhat follows the slope of the FR (inversely). I assume...

I'm currently looking into optimizing the Distortion / output capability of my System (2x Swissonic A306; 1x SVS SB-1000; 1x SVS SB-2000) and would love some feedback on my results! The adjustments I've done so far via a MiniDSP 2x4HD are: SB-1000 HP at 36Hz (LR 48dB/oct) ; LP at 80Hz...

This is a comparison of THD at 96dB SPL average of current cardioid models. If you know of other current speakers and measurements, please post them in this thread. A few notes on the chart above: GGNTKT M1: Data converted from %. Average SPL was 95dB. Sigberg Manta: Data converted from %...

Hello everyone. Just bought a brand new Topping DX3 Pro + to pair with my Ananda. According to Amir's measurements, the amp should clip at about 2 Vrms at a 16 ohms load, which is the headphone's resistance. I put the Ananda's specs (93 db/1mW & 16 ohm impedance) at a headphone calculator and...

I've been reading ASR for a while nowbut this is my first post. Over the past year I have been building an audio system mainly from refurb and used items on ebay, other than one or two new luxuries (well luxury for my budget anyway :) ) My setup for desktop listening: Topping D50 iii DAC (or...

Are high-end gear more revealing of source distortion? I've noticed audio distortion a whole lot more when using my EM10 than when I'm using 7Hz Zero 2 or CX 400-II while I'm watching youtube at 1.3x speed. I'm not sure if the issue is the drivers or the audio compression that happens when the...

Hi everyone - I recently picked up a Umik-1 mic and have been measuring my room, speakers etc. After level matching and swapping amps (speakers and mic in the same position), I have noticed very similar frequency response across the amps (slightly different), with slight deviations in...

So I have this new amplifier aune X7S(2021 version) and here at asr it was measured to have rather high output impedance(about 11 ohms). But I also have a topping L30 II with me and I wanted to sell one of the amps so I compared their sound on the single ended outputs with the Hifiman HE400SE(28...

From 2013 onward, I began a systematic survey of FFT measurements published by some German Hi-Fi magazines. Those magazines belong to a publisher which runs its own laboratory, thus ensuring consistency in the measurement method...

Both DSD64 and DSD128 conversion adds a potentially euphonic characteristic to the sound.

PCM to DSD = better sound quality?

I asked ChatGPT the following question: Upsample before or after DSP to remove aliasing in audio? ChatGPT answered: To remove aliasing in audio, it is generally recommended to perform upsampling before digital signal processing (DSP). Aliasing is a phenomenon that occurs when signals are...

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...

To test the audibility of pure second-order distortion I have written a Foobar plugin which simulates a quadratic transfer function. On the configuration dialog of the plugin, you can set the desired level of the second harmonic in 24 steps between -150dB and -12dB and also turn it off...

Hello all, I am not sure this post belongs here. If it doesn’t I am sorry, moderators. Feel free to move the appropriate section. I am hearing some distortion coming from the center channel and I think it is related to sound leaking from the mains to the center. My system is a Yamaha A2070...

Found an interesting experiment: record a video, upload to youtube and then download/upload it 1000x to see the effects of video and audio compression. The initial experiment done ~2010 with a webcam. Big kudos to that guy, considering the youtube speed at that time it probably took many...

OK this isn't aimed at any one brand of speaker, amp, headphone, etc. I noticed when listening to a FLAC that's been boosted and compressed to death aka loudness wars, in headphones its still pretty clear and not really distorted but just loud, yet when I heard it through the same DAC...
