To be fair, Cable Asylum was specifically and openly designated a DBT Free Zone, which wasn't necessarily such a bad idea given that some folks from the Audio Review forums would routinely come over there and effectively harass those who were simply doing nothing more than sharing their subjective experiences. And indeed, this is what prompted the DBT Free Zone rule.
Of course it didn't help that Risch would routinely go over to Audio Review and poke a stick in that hornets nest which just kept the ball rolling until Risch was finally told to stay away from there.
The problem wasn't the DBT Free Zone rule in itself though. The problem was the way in which it was enforced.
While the "naysayers" were prohibited from bringing up blind testing, the "yaysayers" were allowed to go beyond simply sharing their subjective experiences and make what amounted to objective claims. The DBT rule was then invoked to prevent those claims from being questioned or challenged.

Cables don't make a difference? That ridiculous, of course they make a difference. It's just not necessarily a sonic difference they make.
It can be quite a circus. One of the most vociferous, acidic and abusive cable bashers and champion of scientific protocol on this site for example goes into a long and detailed sighted evaluation of the sonic merits of his amplifier design on his personal web site, values judgments unsupported by measurements correlated with audible thresholds.
It's a social game.
I hope you are aware that your endorsement really isnt a good thing. 😉
I have read enough things about Risch online to know that he isnt what I call a non-bias individual. I would love to have guys like him in a room with I slap $5K in the table and ask him to match it for a test 😉
In the end guys like you and him have too many years of beliefs and tainted subjective experiences to understand what truth actually exists.

Yeah, that is what I read on that forum.
Its a joke to me but hey people have to push what they believe even when they have zero science behind it. Its a good thing that the "believers" do not go beyond just enjoying music 😉
Thanks for mentioning. You would of course note the quotes around all attributes and the lack of any extrapolations to other people preferences, that would require statistical analysis. And of course the correlation between the sound and a wrong compensation on one of the channels.
Or perhaps that's to much to ask from somebody that appears to spend his life bashing people on an Internet forum, with little to nothing in constructive contributions.
But enough about this, you just made it to my ever growing **** list.
I think you did mention something about the benefits provided by the galvanic isolation of your preamp but, as far as I've ever seen, like always couched it properly as an impression. An impression I agree with btw but, always the contrarian, put the transformer in my design on the output rather than the input. 😀
Did you know that the death of Gordon Holt was a hoax organised by his mates?
On something constructive for the diligent skientifik minds here:
Run some parallel SPICE sims using the RLC values for your favourite cables, driving a model of your speakers, and using the RLC values for equal lengths of different cables, driving a model of your speakers.
Plot the FR difference between the two.
That's likely to give a much better picture on just how much "cables make a difference".
For the sake of accuracy that's 200 Hz. Since the primary impact seems to be from inductance, probably not a big deal. Do same for what's being recommended by Roger Russell and Audioholics on the basis cables make no difference. Or play with speaker loads.
Measured response for 25' of 18 gauge was 3/4 dB down @ 20 kHz into an inductive tweeter using an amplifier with no output inductor. That makes the available Spice cable models suspect for me.
Typo, so sue me.
Down to to 20Hz adds a whopping 0.02dB.
The 10' 16 gauge was presented by you as some kind of minimal-requirement cable wasn't it? Plotting its impact on the frequency response alone is pointless. Compared to a much "better" cable with half the R and half the L the overall difference is practically negligible.
Right.
Just like Jakob2 does, John knows all about the sloppiness of all audio related DBT's over the last 30 years. He knows exactly how to prevent all these errors (real or imagined) from creeping into and invalidating the tests.
With this knowledge of how to, he has performed many DBT's himself, with much more robust controls/training/whatnot, where he has listened to and "heard" things like cable dielectrics (no joke).
And like Jakob2, the methods/results/data from John's tests can be viewed/peer reviewed (extremely important - according to John) where?
