distortion

I have been wondering about the following: If we assume a system with a perfectly flat magnitude response after correction based on in room measurements - will the distortions still show the distortion caused by room modes (standing wave causing peak/dip) that were previously corrected and is...

Dear community of addicted to fun and learning, I just found this on RTINGS.com and thought it could be of general interest: The Surprising Truth About Headphone Distortion

hi guys im having an issue with my topping dx5II when swapping from uac2 to uac1 (for use on ps5) so basically i got my new shiny topping dx5II and out the box its sounding great even at low dbs level on the device and high volume on my PC and all is fine in the world then i switch over to...

Hi everyone, I’m struggling to get the audio from the 4.4 mm balanced output of the FIIO KA15 to sound right on my Presonus Eris E4.5 monitors. 1) Buzzing noise on PC. The biggest issue (which does not occur when using an Android smartphone) is a buzzing noise during playback. It happens at...

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...
