I'm a little curious how you picked the B22 and the Bijou as the two to choose between ?
Both fine designs, there is a pretty big universe of projects between the two philosophies.
If it's just because you want a top end amp and want it available as a complete kit, don't
let the sourcing of parts keep you from considering some other worthy designs. Sourcing parts
adds no more than 10% to the time invested in building a typical project, usually less. A small
disappointment in going the kit route is that it seldom keeps you from needing to make a Mouser
or Digikey order in the end anyway.
If the choice is between the B22 and the Bijou. I'm another vote for the B22.
