I used PN2222s and they sound fine.  I haven't compared it to the metal

%Hi Fred!

%Yes I think there is quite a difference in the sound between the TO-92

%The metal cans are Definitely the ones that I use...
%
%www.mouser.com sells these, you just have to put a letter "A" at the
%end of the part number, (2N2222A).
