  I've just watched this for the third time and this time I took notes!  I have just retired and now have time to learn more about Hi Fi and this video was extremely helpful. Nice balance between being technical yet understandable for someone who is not a tech whiz. Add to this is Tarun's typically professional and pleasant presentation.

  One of the best hifi channels on YouTube.

  Wow, you really know your stuff. I'm usually the one teaching others about audio but you explaining how impedance/sensitivity works helped me to better understand it

  <a href="https://www.youtube.com/watch?v=N2LPcU35r50&amp;t=370">6:10</a><br>When I worked as EMC test engineer, we had an anechoic chamber for emission testing.<br>While it was an anechoic chamber made for EM waves instead of air pressure waves, it also did its job for audio.<br>So one time, we had permission to use it for personal experiments on a Saturday afternoon (business was normally closed on Saturdays).<br>Everyone of my test department brought some audio equipment from home to test in the chamber by performing some basic measurements.<br>We already expected that It would sound a bit weird; it&apos;s noticeable while talking inside the chamber, but with music it&apos;s 10x worse, so it sounds very nasty.<br>It&apos;s like there&apos;s a black hole in the corner of the room where all sound is drawn in to; it really kills everything about music.<br>Nevertheless, it was a fun and interesting Saturday afternoon.

  A very good and informative video. &nbsp;One thing not mentioned though, is that a speaker&apos;s sensitivity rating is for ONE speaker, not a pair of them in a room. &nbsp;For two speakers playing in the same room, the output will be 3 dB higher.<br><br>Another thing not mentioned is how live or dead the room is. &nbsp;Highly absorptive rooms will require significantly more power to achieve the same SPL at the listening position as rooms that are highly reflective, such as the one you were sitting in when recording the video.

  You’ve earned your subscribers with quality content. Keep it up…..and thank you for taking out the omnipresent ambiguity in HiFi.

  Best explanation I’ve found yet! Thank you!

  I agree with the others, you explained in a way that we can easily understand not only the concepts, but also their interactions in a very practical way. The other thing I see is that this kind of videos are educational, they help us to be more thoughtful when the inner Max wants to change the amplifier or the speakers without the need to do so. Implicitly we find financial education (... make informed and effective decisions with our financial resources). Thanks for what you do. Keep up the good work.

  Your success is well earned, Tarun. &nbsp;You consistently find the sweet spot between the quantitative reviewers who make our eyes glaze over with graphs, and the qualitative reviewers who do little more than report how a piece of equipment made them feel when they listened to a favorite song. &nbsp;You might want to tweak the reflective surfaces in front of your microphone, though - you&apos;ve got a bit of an echo chamber going on. &nbsp;Other than that, all aces - as usual.

  Very informative and well presented. Sometimes the way something is said is as important as what is being said. You have a gift that many clever people on youtube lack that makes them difficult to learn from.

  I almost never log in to leave a comment, but this is one of those cases. I really love the way you explained this here - this topic has never before made as much sense to me as it does now.<br><br>Best wishes,<br>Lucas
