I have two identical amps, but one of them has a channel imbalance when I turn the volume knob to approximately 10 o'clock, but disappears at any other volume setting; however, this problem didn't exist when I first bought it; what is the most likely cause of this issue?

I've been trying to decide between getting a phono preamp (so I can use MC cartridges with my turn table) and just getting a good MM cartridge. Are MC cartridges really that much better than a similarly priced MM cartridge to justify the cost of getting a phono preamp to be able to use them...

After learning about speaker orders, in combination with being exposed to some recent threads, I came up with a new idea for developing a compensation curve for circumaural headphones: I call it the "Open Air Response" (OA). In a flat open field, with little to no background noise, (like the...

1 (Short): Could the Sennheiser *Headphone Redacted*'s veil be a result of the ~70hz bump rather than the treble "roll-off"? We could make this hypothesis testable by restating it as: "Does emphasizing/deemphasizing certain frequencies alter the perception of others?" 2: Could the acoustic...

I have an Audio Technica LP-120 turntable with an AT95E cartridge and am looking to upgrade. I've heard about Ortofon 2M Reds, but saw the Blue (which claimed to be more linear and less warm than the Red.) However, the Blue is double the price of the Red, and that claim seems suspect to me, due...

A Youtube channel called "Tek Syndicate" made a video back in 2014 debunking audio myths and mentioned amps and headphones in the second part; they said that the point of diminishing returns for an amp is $300 and for headphones that it is $500. However, this was 5 years ago, and both amps and...

I've been looking into frequency response curves and a few things strike me as odd: Why does the ISO 226:2005 equal-loudness contour differ from the free field response by up to 30 dB in the lower frequencies? And, while we're at it: doesn't the concept behind the Harman target seem dubious...

I've been looking at graphs for THD for different headphones on Innerfidelity and have noticed a pattern that exists regardless of driver type: nearly all headphones have harmonic distortion in bass frequencies that reach audible percentages; why is this?

I'm currently making my own headphones and am thinking of using MMCX connectors for removable cables; however, every MMCX female connector I can find has three or four pins, and the drivers I'm using have two wires. Is there a way to connect the drivers to them, or should I use two pin...

What's the model name for the drivers on the Status Audio CB-1? I may buy them for a future build.

I recently received a Tin Audio T2, only to find that the audio was out of phase. My first guess was that it was a problem with the wires. When I replaced them, the problem persisted. Using my knowledge of soldering, I knew I could fix the problem by taking one of the earpieces apart and...
