I say identical, but this isn't strictly the case: for some reason the overall level has been cut on the US CD-layer-only release so that it peaks at only 70.7% of maximum, whereas the CD layer on the hybrid SACD peaks at 99.8%.  In the UK the plain CD version is at exactly the same level as the hybrid SACD.  It's surprising that these international differences can still occur.

The earlier conventional CD pressings of Brauer's mix under the US catalogue number CGK 841 (see earlier note) also had this lower volume level.
