Extremely interesting! I came up with a similar project (in truth, it's closer to the "Snap circuit" you mentioned), which I built 6 months ago,...
One phenomenon not to overlook here is that we are effectively measuring the end distortion of the entire chain DAC->AMP->HP->Microphone, and in...
I was a hard objectivist back in the days too, until I started listening to some gears. Just the other day I was comparing the Topping A30 / D30...
It would be interesting to see the burst / decay response of the grado given how clean/fast the midrange is on the waterfall.
I have uploaded REW measurement report and did some analysis, for those interested: https://photos.app.goo.gl/ssUXULXh32tTUE7UA Yes, but the...
Fair enough. I still wonder what exactly in the design accounts for the massive soundstage difference. I might soon have the opportunity to...
Yes, so that explains the delta in low frequencies, but what's surprising is that this was not even the most apparent difference. Soundstage and...
So, I've spent some time optimizing the setup pictured below, comparing two 3 way speakers in my acoustically treated lab: My DIY speaker...
Comparing BF1 and BF2 on my DIY 3-way Speakers, the difference is clearly noticeable. Interestingly the delta is more noticeable than with...
I'd be interested in the attack/decay 10 wave burst response to see if the meta material has any effect. I expect burst decay to be fast as...
The APX measurement report on Schiit website shows great improvements over "old BF2", especially on IMD distortion (between 20 and 40dB...
Nice! I love the APO bokeh. By contrast, the bokeh on my sigma 50mm 1.4 Art looks rather nervous. I used to look for benchmarks online with point...
So I needed some XLR cables for my Bifrost 2 to feed both my DIY headphone amp and my speaker amp. I ended up going the DIY way using some pure...
I get your point. Basically, you'd like the equivalent of a CSD but for the onset instead of the decay, keeping the time axis as number of cycles....
Constricting the airflow on the back of the magnet had similar effects on THD when I did it on HD58X, but there, the foam improved CSD and...
