This extra hypothesis is not surprising, in view of the idea described in Example \ref{ex:e-n-alg} that an $E_n$ algebra is roughly equivalent data to an $A_\infty$ $n$-category which is trivial at all but the topmost level. Ricardo Andrade also told us about a similar result. \end{rem} \nn{proof is again similar to that of Theorem \ref{product_thm}. should probably say that explicitly}
