This time was Martin Mertens who wrote the review of the Tempesta 20. It has come out today on Fairaudio.de.
I've never known Martin personally. So when the Fairaudio told me that he would have performed the listening session and written the review I was surprised.
If they trust him, I shall as well :-)
...and they were right!

Here You can read it, on German.
The reviewer writes that the Tempesta 20...:
- ...belong to that kind of loudspeakers made for listening for Music
- ...focus the happening where it actually plays
- ...its bass comes to the point, fast, sharp and agile
- ...it scratches in combination with a tube amplifier to the Nirvana of High End
Well, who would want more?
