Thank you!
I just updated it too.
I have been thinking about other components and the amplifier list is a great idea. The problem is, amplifiers are a much harder "taxonomy" for me, mainly because I am ignorant. I am also in the vintage/used world, I would think people tend to buy used amps more than used speakers and that is harder catalogue.
On the other hand, there are less amplifiers overall (I think) so maybe it would be a smaller project. I will think about it for sure.
