Distortion Distortion Distortion


I’ve considered myself a low-to-medium budget audiophile for the past 35+-years. Over these years, while cruising the pages of audio publications (none to be mentioned here), I often read the distortion specification given for various power amplifiers and I’m reminded how critical an issue this once was for my power amplifier selection [back when I was in my mid-forties]. But these days, I am literately forced to over-look distortion -- well, to a point. Why? Well, here’s the bottom line; while attending an audio conference in Southern California (T.H.E. Show) -- pre-pandemic, I sat in on a discussion on distortion. The speaker presented a number of examples of distortion with various audio gear, in great detail, while many in attendance, took notes and calibrated their thinking on acceptable vs. forget-about-it! This is when an audio epiphany rattled my brain when I realized that this was not the critical issue for me any longer. You see, I am now about to turn 81-years of age [Thank You all, I wasn’t certain I’d make to 80 but I have]. Distortion, at 80-years of age, after many years of listening to all kinds of music, often loud, is incidental. I just cannot here the difference in distortion levels and I did experiment with a few different types of amp gear. By 80, the hearing just isn’t as finally tuned as it was at 40. Therefore, I looked at the situation as not needing to spend a great deal of money [as I had in prior years] on gear where distortion was a key criteria [amongst others] -- great, I’m older and now I don’t need to spend as much on a new amp. Ok, so moving forward, I may be contradicting myself but when searching for a great amp & pre-amp combo a few year ago, not that I was looking for the amp with the best [or least distortion specification] but I found that I was really taken by the sound from a Benchmark Media AHB2 power amplified coupled with a Benchmark DAC2 D/A. This is not a plug for Benchmark Media systems, although it may sound like it is, But I should mention, that I learned at a later time, that the AHB2 has the best distortion rating compared to many amps. Anyway, I ended up spending more money than I thought I would need to, despite my thinking previously that I did not have too, but in the end, I am pleased with my selection. Hopefully, even with aging hearing, I can still enjoy great listening time without focusing on distortion.

 

Sorry for the long write up.

@bjcatanzaro Distortion, for the most part, is the differences you hear between components. For example the smoother tonality often attributed to tube equipment is due to harmonic distortion.

Our ears use higher ordered harmonics to sense sound pressure to are keenly attuned to them. This is why older solid state amps often sounded bright even though on the bench they measure perfectly flat.
