My recent review of the Topping B200 monoblock amplifiers stirred up some criticism of my choice of speakers for testing (not that I had a choice - they're my only passive speakers right now). The result is this conversation explaining what matters and what doesn't matter when you're choosing an amplifier to drive your speakers (or choosing speakers for your existing amplifier).

This is my response to DMS video about burn-in in headphones and some of the comments I saw on that video and on a video of mine that followed.
Key topics in this episode:

• One, well executed, but narrow test does not equate to a global truth
• Assuming the motivations of other people's actions is dangerous ground
• Why there is still more to the sound of a headphone (and it's burn-in if that exists) than its frequency response graph
