    What's the highest frequency you can hear?

    Speculation: Maybe you can hear the lower frequency harmonics that come with the frequencies above 15 kHz? At bass frequencies there is a mechanism where emphasis on the high frequency harmonics of a low frequency tone can make your brain think it hears the lower frequency tone. Maybe something...

    What's the highest frequency you can hear?

    17 kHz and higher is good for chasing away teenagers: There typically is not much information in music above 12 kHz, though I do remember some songs of the past sounding more crisp and...

    New system Vocal Distortion

    It has been tested as well: No distortion peaks in the tweeter.

    New system Vocal Distortion

    The Elac tweeter has a narrow distortion peak at 9 kHz: It starts at 8 kHz and ends at about 11 kHz. 2.5% distortion at 96 dB. Maybe that's what you're hearing.

    Am I deaf? And what is the next step up?

    How did you balance them with a multimeter? A small difference in output voltage can yield a small difference in music volume level which could explain the difference you hear. Also, you can adjust bass and treble on a chromecast using the google home app. Could this be the answer? I also...

    Amplifier measurements may require improvement

    Another remark: The sharper dips in the frequency sweep of the Fosi could be the result of lower harmonic distortion. If there is destructive soundwave interference at a specific frequency, harmonics of that frequency will still reach the mic and increase measured SPL. Hence, a higher THD makes...

    Amplifier measurements may require improvement

    Thanks for joining! Amir also tested other frequencies into 4 ohms by the way. Someone already remarked it could be due to a gain difference between the amplifiers. A low voltage level input signal will then never be amplified beyond a certain output voltage, i.e. the output voltage would be...

    Amplifier measurements may require improvement

    I get the feeling that, since the white noise sounds very different AND the dips in the frequency graphs are different for both amps, he did not use the exact same mic position for both amps... These dips in the higher frequency are cause by destructive interference of sound waves coming from...

    Amplifier measurements may require improvement

    Don't know if the Ti differs. What is very odd to me, though, is that the white noise sounds very different through the Yamaha compared to the Fosi, even at low volume levels. Listen from 14:40 in the video: This is strange since the response graphs look identical for low volume levels. He...

    Amplifier measurements may require improvement

    This is impedance graph of the Tannoy DC8T: According to the test, "The bass unit has a very low DCR of 2.7 Ohms"...

    Amplifier measurements may require improvement

    It does not drop below 6 ohms, so seems very amplifier-friendly to me.

    Limits of Current Amplifier (PA) Tests

    Differences in delay for different frequencies are non-existing for amplifiers. They amplify the time domain signal, containing all frequencies therein. They do NOT split the time domain into different frequencies and then amplify each frequency seperately. If a complex note, containing...

    Stereophile 2023 recommended gear list

    On their recommended list is a $363.000 turntable... the OMA K3. That made me curious... Test is here:öder-tonearm Hilarious, just from the quotes alone: Reviewer won over.. I guess Newton's law of inertia no longer...

    Master Thread: Are measurements Everything or Nothing?

    I totally recognize that. Some weeks ago I stumbled on a nice, small, sturdy remote keyboard that was perfect for remote controlling my audio PC. Much better than the bulky one I used up till then. When I installed it and was using it the first time, I was so happy with it that the music...

    Master Thread: Are measurements Everything or Nothing?

    I'm not a subjectivist nor an experienced electronics engineer. But I do have two serious questions related to this debate: 1. Measurements are often done with one frequency at a time (frequency sweeps and harmonic distortion) or sometimes two frequencies simultaneously (intermodulation...

    (UK) Quality Digital Coaxial Right->Left cable?

    If your left speaker does not have an AC in connection, it will not contain a DAC nor an amplifier. In that case, the wire acts as a normal speaker wire. Maybe you can try one of these if you don't like soldering:

    Rca or optical ?

    I use a Topping D10 for usb to spdif conversion. Works perfectly. The D10S and the D10B both have coaxial as well as optical spdif output. I use the optical one at 96 kHz, 24 bit without any problem. A digital interface cable works a bit like this: Imagine you have someone on the phone who only...

    Edifier R2850DB Review (Opinion)

    There's a youtube channel where they record side by side comparisons of studio monitors. With good headphones, this gives an impression of differences between speakers and between the original soundtrack and the recording of the speaker's sound with microphones. Not a perfect listening test, but...

    What Hi-Fi's Amp Reviews: A Basket of Unmeasurables?

    I don't think you need to understand the graphs to read the excellent reviews here. Just the remarks made in the graphs and the conclusion gives way more and way more objective information than a What HIFI review. I wonder if they always play the same tracks when reviewing an amplifier. If not...
