distortion

Slate Digital Fresh Air vs. Fabfilter Pro • Q³ which is better to bring the air into music?

I'll try to explain this the best way I can. I am running a CD Player's digital output (tried both COAX and OPTICAL) into the Holo May DAC. Then I have the XLR output from the May going into the XLR in's of a Cambridge EVO150. However, when I play the music the sound has a horrible midrange...

I was watching Amir's excellent (and long :-) video about how Harman and other sound engineers determine objective and subjective sound quality. I'm pulling out my question to a separate thread because it's a different topic. My question: what causes information *loss* from speakers...

Hi all! I've been hearing some strange things lately on out of my Aune X1S. I can't seem to find it inside of ASIO4ALL and there are strange distortion spikes. The first image is my onboard soundcard and the second one is my Aune with the fast filter selected. I just want to know if this could...

Hi All, This may be a bit of a long shot, but I am working on a system which has a DSP generating 3 frequency tones @ 400, 800 and 1600 Hz via a codec (TLV320AIC3106) this is picked up by a microphone via another codec (SGTL5000) and an fft is done on the recorded signal. 99% of the time...

Hey, came across a wierd problem, my Denon 4700 distorts any music I play via Heos, the highs made me think my DBR62s had turned into a B&W ;) Apparently looking at the 4700 thread Im not the only one encountering this problem. Has anyone found a solution yet, seems to be a software issue. Thanks

Topping D10s USB DAC I bought this little DAC from Audiophonics France https://www.audiophonics.fr/en/dac-without-volume/topping-d10s-dac-usb-32bit384khz-dsd-256-xmos-u208-es9038q2m-black-p-14686.html It has arrived after 6 days from purchase. I made some measurements : Output Noise Noise is...

Following the assumptions on possible influence of ultrasonic noise and carrier frequency residuals to tweeter output I have prepared an experiment where the tweeter is driven by 2.82V sine tone of 6kHz from 2 different amplifiers. One of the is AIYIMA A07, see my review...

Howdy, this topic got hot in the JBL 4309 thread. A lot of very interesting points have been mentioned in that thread. Let's make the jump to a dedicated thread. Maybe the mods can move some relevant posts here so there is some context and fuel to work with in this thread. Things discussed...

Extensive study of IMD (and THD) distortions on 4 amplifiers with different topology THD+N (SINAD) at 1kHz and 5W power has become a comparison measure of amplifier parameters here in ASR. I would like to demonstrate my deep persuasion that much more complex view of amplifiers distortion...

Hello everyone, I'm getting used to using REW with my UMIK-1, along with setting EQ curves for my 2 subwoofers using a MiniDSP 2x4HD. This is a pretty standard auto-EQ I did for my subs with a mini house curve. I didn't really do any individual tweaking yet (there are definitely a couple of...

As some of you guys might know, the famous Rob Watts has mentioned on more than one occasion that he can hear and measure distortion down to -300 dB. Cited by @amirm here for instance. He also says something similar in this video: Staring at roughly the 17min mark. Now I was thinking about a...

Good day everyone - So I’ve been looking into various methods of applying a cardioid response into different designs - things like resistive enclosures, active methods with rear drivers, and such The thing that concerns me is that I’ve always wondered if it’s actually worth the effort - I’ve...

Comparison of AIYIMA A07 with DIY class AB amplifier into complex speaker dummy load (and more amps added soon) This is a measurement comparison of AIYIMA A07 amplifier (powered by SMPS Mean Well RS-100-24 27V)...

For the past few weeks my desktop setup has been having crackling audio at any volume. High DR and low DR has the same crackling. The oldest part is my Sansui 2000A. You can only hear noise at max volume but its very faint then. My dac is the Topping E30 and my speakers are the Elac Debut 2 b62...

As we all know, headphones, similarly as speakers, have non-linear and frequency dependent impedance. This non-linear impedance creates a divider with headphone amplifier output impedance, so the distortion measured at headphone amplifier output (behind its intrinsic output impedance) would...

I wanted to compare amplifiers measured elsewhere to the ASR standard measurements: SINAD at 5W in 4 ohms, and power at 1% THD+N in 4 ohms. So I chose some amplifiers that interested me more (let me know if you wish I can add more), read their graphs, converted to SINAD, color coded and created...

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'...

Quick question. I do not understand why we fuss so much about distortion in a DAC which might be at -100db rather than -130db when the best speakers that have been tested here have second harmonic distortion at around -70db. How does it work, do they sum up? Or because the speakers has...
