  A detailed comparison of QMC/DMFT results for the non-isotropic two-band
Hubbard model by Liebsch [Phys. Rev. B 70, 165103 (2004)] and C. Knecht, N.
Bluemer, and P. G. J. van Dongen [cond-mat/0505106 (submitted to Phys. Rev.
Lett.)] is given. Both results are shown to be in excellent agreement. Thus,
the claims by Knecht et al.: ``The second transition [was] not seen in earlier
studies using QMC and IPT'' and ``Our high-precision data correct earlier QMC
results by Liebsch'' are shown to be unfounded.
