The Grande Messe des Mortes by Hector Berlioz is always put to use when it becomes essential to find out how much overview is maintained when things get really intense. Lots of percussion and hundreds of singers are challenged by the musical score here. "Dies Irae" unleashes an exceptional contest between the various choirs and the orchestra musicians, whereby the translation "Days of Wrath" precisely discloses the spirit of the composition. Even within these elemental forces, the Ultimate keeps its countenance. The speech intelligibility of the innumerable voices is preserved, and the various groups of singers are also stably projected into the room, while the low-tuned timpani wave a sound carpet that creates the desired menace. Here the amplifier’s potential also allows for the necessary calm throughout the performance.

An epic work of jazz is without doubt The Köln Concert by Keith Jarrett. A lot of things went wrong in the run-up to this concert, but perhaps it was precisely these ailments that subsequently revealed the ingenuity. However, this contrasts with the performance. The grand piano is physically projected into the room, while not only the strings but also the resonating body of the instrument fill the room with sound. Moreover, here the perfect timing of the accented notes is veritably celebrated. And the rhythm in particular. The Ultimate appears to be one of those wonderful rocking animators: Just try it out!

After experiencing another wonderfully performed jazz classic, "You look good to me" by Oscar Peterson, a highlight of the listening session followed: "Liberty", intoned by the Norwegian artist Anette Askvik. With regard to this, here's a gentle hint: The recommendable album of the same name can now be mail-ordered on her website at a moderate price. Absolutely fantastic how beautiful the Struss Ultimate reproduces the vocals. The imaginary not infinitely deep soundstage makes the speakers almost disappear, while again the instruments are orchestrated in a natural way. It's the voices and the acoustic instruments that this amplifier is celebrating. Yes, Mr. Hrynkiewicz-Struss masters the technique of passive preamplification as well as the construction of high-performance power amplifiers. And now it’s about time to put down the tablet computer and conquer the record rack.
