The review was conducted by Tony O’Brien, a certified ISF Calibrator and accomplished Audio-Visual reviewer specialising in theatre and visual products. After a thorough review of our ISP 32 Analogue MK2 and PA 8 MK2, his verdict is:

“Storm Audio’s ISP.32 Mark 2 and PA8 Mark2 Ultra High Power amplifiers must surely have been a labour of love for their creator. And as luck would have it, it’s seemingly ongoing – evidenced by the fact that the ISP Mark 1 is both still upgradeable and expandable.

Admirable as these features are, they don’t count for much if the products don’t sound the part – but that was not an issue here. Capable of producing a sonic storm, the sound field is wonderfully dynamic and powerful sound – truly cinematic. Yet, it’s not just about brute strength, as this duo has a wonderfully transparent sound that reveals the subtlest of details. As such, this dynamic duo is an absolutely essential audition.“
