    Magico - 2022 interview with Alon Wolf - he's a big measurements guy

    Very interesting interview. For such a perfectionist I wonder why he doesn’t use a real anechoic chamber. I think Andrew Jones said he doesn’t think klippel is actually as accurate as it’s supposed to be. Maybe that explains the imperfections in the measurements?

    Analysis of Paper on Measurements of RCA Cables by Kunchur (Video)

    which is why he says phase integrity is so important we should all be rushing out to buy Wilson Audio Chronosonics

    Analysis of Paper on Measurements of RCA Cables by Kunchur (Video)

    Here's kuncher's video on this. He mentions the calculations for time delays and frequency. He starts off by explaining that time delays affect timbre and makes a very interesting comparison of the frequency spectrum between a piano sounds played forwards then backwards to demonstrate...

    Analysis of Paper on Measurements of RCA Cables by Kunchur (Video)

    Whenever someone points out that the measured frequency response or SNR of a product doesn't support its claims, 9 times out 10 I will hear 'cause the problem is in the time domain and not frequency domain because humans have evolved to can notice differences in microsecond yadayadayada...'...

    he said your name! sad to hear he won't be doing anymore flat earther videos..

    How do we know that? That's why we need a video..

    But we're not talking about AC here right? Isn't this about speaker current? I can see how reactance can affect the amplitude but I still don't see how it can mess up their timing

    Yes but what he is implying is that different frequencies are being delayed differently so you get smearing.. at least that's what I think he's saying

    GR Research Upgrade for Klipsch RP-600M Speaker (Video)

    There's not a lot of supporting material in his video but it sounds like he's saying that EQ alone doesn't fix phase issues (smearing?). But I'm not sure how something like a crossover would cause an electrical signal to smear in the time domain. Anyway I'm enjoying these back and forth...

    Brilliantly timed video. Out 1 day after Danny's attempt to ridicule the test

    GR Research LGK 2.0 Kit Speaker Review (video)

    I don't understand why some people don't like recordings of speakers. I got more out of this video because it had a recorded example and explanation of how a speaker distorts.

    Choices of eq+cossover device that is as good as direct DAC to amp?

    The problem I think is that you're looking for an external crossover solution that measures as well as one in a commercial speaker but afaik the passive crossover networks in commercial speakers are designed and built to match the specific properties of that speaker and external solutions just...

    Choices of eq+cossover device that is as good as direct DAC to amp?

    There's other options if you look at the diy community

    Choices of eq+cossover device that is as good as direct DAC to amp?

    I don't think it's worse than minidsp because its purely analogue and much simpler (no adc) but some measurements here: https://josephcrowe.com/blogs/news/xkitz-2-way-active-crossover
