Huh?  My example works just fine; it's yours that is broken (since '' 
surpresses the innermost $() command substitution):

$ echo "$(echo '$(echo 'a  b')')"
$(echo a b)

By the way, $() is saner than `` when it comes to nesting and "" (as required 
by POSIX):

$ echo "$(echo "$(echo 'a  b')")"
a  b

Here's the same thing in properly quoted ``, at least when using a POSIX-
compliant shell (in general, "`""`" is non-portable, since other bourne shell 
implementations parse it differently than what POSIX requires):

$ echo "`echo \"\`echo 'a  b'\`\"`"
a  b

(in examples like these, I like to use two spaces to guarantee that I've used 
enough quoting)
