  Im just here listening to this at 3 AM. I dont even think if I'll remember any of this when I wake up later but damn the information and presentation is 10/10

  Excellent video. One suggestion. Slow down your presentation. This is very technical information for most of us that needs time to soak in. My two cents worth.

  This is really good. I'm really glad that you focused more on current and output impedance, because I think most people think of amps as a tool for applying more voltage.

  I never had the courage to tell anyone on HeadFi this, but back in 2003 I drove a Sennheiser HD600 directly from the line out of my parent&apos;s old Technics CD Player. I used a stereo RCA to headphone adapter that had a potentiometer on it for volume control. It sounded pretty darn good, and I didn&apos;t notice much difference from a cheap portable headamp I could afford at the time. Notably, the line out had no problems driving it to ear splitting volumes. <br><br>Perhaps because the HD600 is high impedance. Or maybe I was accidentally altering the frequency response and solving the HD600&apos;s bass issues (although back in those days nobody complained about the HD600&apos;s bass output....it was &quot;the veil&quot; in the treble people complained about....and ironically people insisted the HD650 was less veiled when it came out, when FR graphs would later on show otherwise....shows how much we are influenced by wishful thinking / suggestion!)

  It would be amazing if you guys make some sort of audio gear link calculator to make the process of DAC-amp-headphones selection easy for non technically savvy users easy (i.e. include a dozen models of each category in pull down menus and when user selects one category the system presents best options in the other 2 cats)

  Thank you. <br>I am literally so uneducated in this field, that this is making my head hurt with information. I&apos;ll watch it again a couple times, and maybe that&apos;s will help.

  Great vid... I wish I had this years ago when I got started into the hobby. I was so lost for a long time before it finally clicked.
