For anyone reading the archives: using a headphone amp to boost the
signal further is probably *also* going to increase the odds of burning
out something, probably the amp input, but possibly the headphone amp.

Headphones, speakers and line-level inputs or outputs are not
electrically compatible.

What he needs is something that generates a line-level output, which the
headphone socket can't deliver.  You might get something that had a
headphone input on one side and a line-out on the other...
