Default List of best DIY Headphone Amplifiers

Since there are so many DIY headphones out there now wouldnt it be nice if we would share and make a nice list and links of them?

What do you guys think?

Just sort the page by most views ranked in descending order. That will give you a list of the most popularly viewed amps on this forum. Does not correspond with "the best" but gives some indication of which ones members feel are worthwhile or interesting.

For dynamic DIY headamps, there won't be anything that would touch the level of Beta22 and balanced Dynahi (Dynamite). The Sjostrom QRV-08 is also fantastic, reasonable cost, but quite low powered. I also really like the Millett Hybrid Maxx, good stuff, well documented and easy build.

I'm gonna follow this thread. I was away from HeadFi from about the time the MH Max came out till just recently. There is hardly anything in the DIY section regarding amps anymore. It used to be pretty busy back in the day, but I think the ban for group buys looks like it killed the diy section there..

How does the Beta22 claim to be full Class A 18w into 8ohms while using such small local heatsinks and only 180mA bias? Furthermore, it says that heat output of the heatsinks increases as music power goes up. Sounds like Class A within first 180mA and Class B above that.

push-pull Class A should give 2x the bias ~360 ma - enough for many headphones

Always a give-away that an amp's not fully classA over all output powers, when it gets hotter the louder it plays.
