I only just got it the other day, but I like it very much.
Recently I usually don't compare different performances of the same work. I just tend to listen to and appreciate a performance on its own merits. But, I decided to compare this one to Joseph Kelemen's performance on Oehms SACD. It was fun.

I chose to focus on Schildt's Magnificat. Quite different approaches from the 2 organists. Kelemen's performance is much bolder with a quicker tempo. This makes the piece feel like a large, powerful work. The large Arp-Schnitger organ (built in 1692) also adds to the overall effect.
Berben's performance is more intimate with a slightly slower tempo...bringing out the solemn characteristics of the music. Built in 1624, the Hans Scherer organ is of an earlier generation than the Arp-Schnitger, but contemporary to Schildt.
The surround channels are ambient, but both Oehms and Aeolus do an excellent job recording these 2 wonderful instruments. There is plenty of resonance of the recording venues to make the soundstage naturally immersive.
If you're new to this music, Kelemen's recording on Oehms might be good because it includes major works by Nicolaus Bruhns and the performance is a bit more exciting.
Berben's recording on Aeolus is also very good. It contains music by Delphin Strungk, a little known contemporary of Schildt. And the Hans Scherer organ gets us back to Schildt's teacher Sweelinck. It's a good disk to chill to.
