An Engineer in Wonderland – A well-argued headphone amp design

There is a lot of hype in the world of high-end audio.

And few reasonable people who seem to know what they are talking about, and are prepared to burst bubbles.

One such blogger and forum sage is Northwest Audio & Video Guy

He*, has gone so far as to design his own reasonably-priced headphone amplifier to show what can be achieved without paying a fortune for nonsense.

And, the best thing for me is that NwAvGuy has written immense blogs that clearly describe the choices and compromises required for the amplifier, and it is all backed up with measurements.

Here are those glorious blogs:

Lots of facts, no hype.

A bonus is that NwAvGuy has open-sourced the whole design.

Sadly, I have ear-buds in tin ears rather than golden ears wrapped in headphones, or I would just have to make one to see what it sounds like.
