One thing that interested me about the StormAudio ISP Evo is that, despite its obvious hi-fi function, it's more like a computer than a typical "prepro." While it does offer a few "legacy" analog inputs, it is for the most part all-digital, input to output, including network connections on both ends. Consequently, it is less likely to leave sonic fingerprints on the music than devices that convert digital to/from analog or modulate their signals with active amplification or attenuation. It is notable that, despite its audio function, the Storm completely lacks traditional audio specifications—distortion, dynamic range, and so on.

Yes, that aspect of the product was appealing, but the real trigger for me was that when I began this review, the StormAudio ISP Evo was the only consumer device to fully incorporate the latest version of Dirac Live Active Room Treatment (ART).

Performance ****
Sonics *****

Concert arrangements of operatic themes for piano, like Liszt's famous concert paraphrases, obviously provide an opportunity to display one's virtuosic keyboard technique. As Denis Morrier's program note for Harmonia Mundi indicates, however, transcriptions of Wagner served a second important purpose: spreading awareness of the composer's operas when they only played in a limited number of venues. There was no Spotify or Idagio back then!
