Wouldn't it be great to be able to overlay the various amps' measured graphs for comparisons?

Hi. A few years back I was in the market for "my last" power amp(-s) and being an engineer and in Sweden, that means spending time at faktiskt.io.

This was before ASR and the sources to measurements were scarce and not easily comparable so I used a tool to extract the raw data from published power2THD and freq2THD graphs, went about it in Excel and published a few combined ones as the following ones for the most promising ones I found at that point in time. Maybe I have missed it but shouldn't we be able to have Amir dump the data to a similar tool as https://crinacle.com/graphs/headphones/graphtool/ (it was previously open for everyone), or https://www.headphones.com/pages/build-a-graph..
Connecting this new tool to the review tableu index and have all that data available seems very useful in discussing, research before purchase etc. Adding speakers and DACs as well wouldn't be that hard. I don't know a tool but I know Javascript libraries are very powerful these days and there should be talent, will and persistence in this forum..?

Now, here's examples:
It really shows how good the Benchmark and nCore500 was/is. (BTW, I went for two Anaview AMS1000, good enough for my ears and room)

(Don't mind the "kkr" parts, that's roughly the SEK cost of the amps in Sweden (and blu-white lines are class D, red-yellow class AB).)

My spreadsheet is just simple reading of graphs and eyeballing numbers for several entries. This is next level work, congrats!

If you or someone could use these automated reading tools to extract more precisely the data from the various sources I have listed, and have them displayed in a same graph dynamically (user chooses which amp to plot) it would be awesome.
