  We report measurements of the nuclear modification factor, $R_{
\mathrm{CP}}$, for charged hadrons as well as identified $\pi^{+(-)}$,
$K^{+(-)}$, and $p(\overline{p})$ for Au+Au collision energies of $\sqrt{s_{_{
\mathrm{NN}}}}$ = 7.7, 11.5, 14.5, 19.6, 27, 39, and 62.4 GeV. We observe a
clear high-$p_{\mathrm{T}}$ net suppression in central collisions at 62.4 GeV
for charged hadrons which evolves smoothly to a large net enhancement at lower
energies. This trend is driven by the evolution of the pion spectra, but is
also very similar for the kaon spectra. While the magnitude of the proton $R_{
\mathrm{CP}}$ at high $p_{\mathrm{T}}$ does depend on collision energy, neither
the proton nor the anti-proton $R_{ \mathrm{CP}}$ at high $p_{\mathrm{T}}$
exhibit net suppression at any energy. A study of how the binary collision
scaled high-$p_{\mathrm{T}}$ yield evolves with centrality reveals a
non-monotonic shape that is consistent with the idea that jet-quenching is
increasing faster than the combined phenomena that lead to enhancement.
