Hello! I would like to build an amplifier for headphones. I've found several popular schemes in the Net:

http://gilmore2.chem.northwestern.edu/projects/cmoy5_prj.htm
http://diyaudioprojects.com/Solid/Tube-Mosfet-Hybrid-Headphone-Amp/
Which of these schemes will you recommend for optimal work with headphones with resistance of 32 ohms?

Hi, you might get some answers here, but to get more feedback from DIY experts you might check the forums at www.head-fi.org and especially at http://www.diyaudio.com/forums/headphone-systems/

I don't have any experience with the amps you are looking at, but the middle one (morgan jones) has the best reputation.  There are also later derivations of that design.

Do you have experience with tube amps, or tube gear in general?  A standard tube amp generates lethal voltages, so it is not a project to be treated lightly.  For headphones, there are low voltage options available, that are safer.

If you are comfortable with the voltages, also a question of budget, and how much work you want to do.

There are places like this

that sell pwbs or kits
