Tony gets money from hosting advertising on pfm. I don’t know how it works, exactly, but I assume his fees are related to footfall, eg how many ads are loaded. That correlates directly to the number of page views, which depends on the number of visitors, how long they stay, and how many threads they view.Point being?
I’ve learnt a thing or two about forums in the past 17 years pfm has existed and you absolutely need that 1/3rd registered to 2/3rd guests online ratio. Go too far to the former and it is clear the SEO is very broken as people aren’t finding the content, too far to the latter extreme and chances are its a nutter-blog and people are just rubber-necking a train-wreck from afar.
In theory yes.Just an aside... Subjectivism isn’t anti-science or pro foo. It simply means that kit is assessed subjectively, and that can be done with scientific rigour.
Weren’t mp3 codecs developed using rigourous subjective listening tests, figuring out how much data can be lost before it’s audible?

Indeed.Went for a look. Said I had to login as guest. CBA.

An interesting subject for a thread maybe?
My take on it is that of course things need to be assessed subjectively as well as objectively. Amplifiers for example can sound quite different from one another and for reasons that cannot be predicted merely by measurements
I agree with this, yet you don't consider this to be even a possibility for something like cables?
Did you read the rest of mine? Can you explain the mechanism whereby signals propagate in a conductor at radio frequencies in one way, and at audio frequencies in another, and at DC the current propagates differently still?Did you read the rest of my post? It's not possible for cables to make a difference*... this is where my exasperation starts... a bit of electrical knowledge soon shows that it's impossible.. in fact ludicrous to even contemplate...

A point to ponder:
The audio frequency band (nominally 20Hz to 20kHz) spans around 10 octaves. The band from the top of audio to VHF is much the same, yet nobody argues that cables behave the same at VHF frequencies as they do at audio frequencies. So somewhere between audio and VHF there is a transition where the cables behave differently. It is clearly not a hard transition, but a gradual one.
So can you seriously argue that the transition is not happening within the audio spectrum (noting that the bottom of the audio spectrum is close to DC, which is a very different animal as far as propagation goes - so is there not an argument that the bigger part of the transition happens between DC and, say 1kHz, rather than from 10kHz to 2MHz?). And if it is happening within the audio spectrum, can you argue that it might not, under some circumstances, be audible?
Yes you can. There isn't a point of transition, but a continuum. At one end the difference s will be utterly negligible, at the other end significant. Maths will tell you at what point a change is significant. Resistance in a mains cable is a bad thing, if I had a cable with 100r resistance it would be useless. So how do I know that my actual cable, with 0.01 r resistance, isn't a problem? Because it's in the textbooks why not. Same goes for effects that only matter in the MHz range.I agree with this, yet you don't consider this to be even a possibility for something like cables?
