That's a really nice video. Good find, thank you.

I most definitely have ... that’s why I put away my spec sheets .. I remember during the period when yamaha’s ‘natural sound’ amplifiers and components were a thing ... maybe around 1980-82 ...? They had me believing that nothing less than 100 wpc and one part per million THD would do the trick ... then I heard a few amplifiers ... one rated at something over 0.1% THD ... maybe the most transparent sounding amplifier I ever heard before that point... and then I heard one of the first model mark levinsons ... maybe the most powerful amplifier I’d ever heard ... and it was rated at something around 18 watts maybe (?) ... but of course was capable of absurdly high transients .. this opened a whole new world for me ... of course much of this is probably due to my own fallacious assumptions ... but so are the experiences of others I suppose ..?And yet I’ve never heard anything that measures less than optimally that I could live with - when I think of all my favourite equipment, it happens to measure well too.
Brings us back to those pesky ears and brains, and their unreliability again doesn’t it?!
There is a legion of b*llsh*t and many unscrupulous vendors looking to exploit the unwary, and a vast amount of anecdotal misinformation. Please don't stifle this debate beyond dealing with obvious rudeness. I believe you greatly admire Peter Walker - a good sound honest engineer who would have had a very pithy response to many contemporary audio claims.
They sound different because they use differen amplifying devices and produce different distortion spectra, have different bandwidth, slew rates and damping factors, etc. I don't think there is a conundrum.I take your point and agree that basic measurements are necessary if one is to make and sell an audio product to a wide audience, but I am not sure that much equipment today, including valve/tube designs, actually measure that poorly. I bet most will cover the 20Hz to 20kHz bandwidth (-3dB) needed for good audio fidelity and produce acceptable levels of THD & IMD, and if well designed should be low noise too.
I think the word "distortion" is over used, and also used incorrectly, unless it can be shown by measurements that substantial distortion is being produced, as a means to describe the difference between a solid-state amplifier and a valve amplifier as you mentioned earlier in this thread. I make both types of amplifier and its interesting to see how different they sound, but both would pass what would be easily accepted in a magazine review. So why do they sound so different? Now that is the conundrum!
I remember back in the late 1990s I was asked to test and evaluate a very special custom made solid-state amplifier. It was totally hardwired with a linen jacket cable with stranded PC-OFC wire, which was a nightmare to cut, dress and terminate. It used special hand made resistors and a whole host of other custom made parts. It was beautifully built and produced about 40 watts of power and sounded absolutely fantastic, probably the best solid-state amplifier I ever heard, yet when I measured it, the feedback free design started rolling off at around 8kHz and was 3dB down at 15kHz. The bass was OK as that was 3db down at around 5Hz. The amplifier was produced and sold worldwide and many people loved its sound.
If a thread is objective or subjective, then neither can comment on the other.
Hi,Bit totalitarian don't you think?
Because it is what they listen with and how they process the incoming information.Neither your ears nor mine are analytical instruments and everything they detect is filtered through a really, really unreliable grey computer that doesn't work the same from one day to the next.
I might as well ask "Why do some people think that their ears and brains are in any way reliable as listening devices?"
Probably. That's why they're hifi enthusiasts in contrast to music lovers striving for the best experience.I'm saying that your measurement system is crap, so you can't talk about "fidelity". If you don't have a reliable measure then you can talk about "enjoyment" all you like, be my guest, but you can't suggest that anything measured with an elastic tape measure is "accurate". Hifi enthusuasts like to talk about "accurate", don't they?

Why is that daft? You don’t have to be completely one camp or the other. This isn’t an adversarial court room.One of the many daft things about this discussion is that even CK has joined in the "objective naysaying" in the past. https://pinkfishmedia.net/forum/threads/ethernet-audio-cables-really.212132/
Some mutual respect might be nice?
