I recently found a recording of the music from Girls und Panzer by the Tokyo Symphony Orchestra. The OST to the anime in its various forms was probably generated in a digital audio workstation with sample libraries. It’s quite listenable, but virtual orchestras can’t compare to well-recorded real instruments played by real, living musicians. The bass drum alone makes the upgrade worthwhile, particularly if you have powerful speakers or good headphones.1 The only disappointment with the TSO CDs is that they’re missing “Yuki no Shingun.” 2
Incidentally, I ordered the CDs from Amazon.co.jp on a Sunday, and they arrived the following Tuesday. If you want the quickest delivery from Amazon, forget Amazon Prime. Order overseas.
