Jaap Veenstra of Alpha Audio checked out the PA1 monoblock amps in a high performance audio system. And he became very happy of what he heard, even offering it their ‘Alpha Approved’ award!
“What’s also striking is the coherence in timbre across the entire spectrum. The bass blends seamlessly with the midrange and treble, even at higher volumes, which can sometimes go wrong with power amplifiers that aren’t as well-designed as this PA1.

Rhythmically, too, it’s all put together exceptionally well. When we play “Pneuma” by Tool, for example—an incredibly beautiful song in which (as befits Tool) the drums carry the track—everything holds together effortlessly, and we can follow it all with ease. In fact, we’ve never heard this song sound this good! The layering is simply unparalleled.
And that brings us to the final point: control and calm. Because the Grimm PA1 maintains control so effortlessly and shows no sign of compression (or other distortion), everything holds together effortlessly. And that brings calmness to the music. Impressive!
What a remarkable product yet again. Grimm just keeps coming up with gear that’s simply top-of-the-range. We are, and always will be, big fans of this wonderful company from the Netherlands. The Grimm PA1 ticks all the right boxes: smooth, transparent, rhythmically accurate, controlled… Of course, they don’t make the music themselves. But they certainly know how to present it in a truly compelling way. Hats off to them. Alpha Approved!”
