Different harmonic distortions at different places?

Why would you get different measurement results for harmonic distortion at different places? In several of our other blogs, we talked about harmonic distortion. https://testhifi.com/2019/03/15/the-sound-of-distortion/ David explained why they are. Also we talked about acoustical […]

You can hear the difference – listening example

Any system plays music it is just a question of how close it comes to the original. The question of hifi, high fidelity. The two audio files attached play the recording’s taken at the same […]

Position is key

Influences to the frequency response Sure, we all know about and talk about the frequency response. Measuring amplitude over frequency. Of course, this is far too profane for a proper audiophile to have a seriously […]

Air between the tones

Very subjective view on some highly appreciated sound experience events This time I write about air between the tones and some of my recent listening experiences and about some thoughts about better measurements of sound […]

Simple pleasures

During the last weeks, I enjoyed some 300 surplus LPs from a friend. Very nice ones! Browsing through them with a minimalist vinyl setup: turntable, solid state phono- and chipamp into Betahorns.I am spoiled by […]

Bluetooth Signal elongation

Sometimes when measuring – how we found the issue Bluetooth signal elongation? One would expect, if you transfer a signal, the signal you receive equals the signal that was sent.  When we were developing and […]

Fast Fourier Transformation

Today, Fast Fourier Transformation (FFT) based analyzer software is cheap or available for free. One such very nice and free program is REW (Room EQ Analyzer). It can do much more than analyze room acoustics, […]

Frequency response left versus right, sum and stereo

Frequency response This is quiet an established measure, of course. However, even frequency response is not fully accepted. We wrote several blogs related to flat response or peaks and drops in frequency response and we […]

Tube sound again

For objectivists the characteristics of tube amplification is mostly due to additional components of sound. Many tube lovers call it a higher purity of sound.Others again enjoy „easier listening“ in terms of warmer and maybeslightly […]

Signal path through a tunnel or what actually limits good sound?

Trying to determine criteria for good sound and looking for support to determine it better. Since decades professionals and audiophiles measure sound parameters and yet it is not possible to fully predict the sound quality […]
