Depends what you mean by unique. Olafur's stable mate, Nils Frahm has some great music (I have all his albums on LP), particularly his albums 'Screws' and 'Felt' and 'Solo'. I'll likely play some Brian Eno/Pat Metheny from their album/Ep 'Electric Counterpoint' - the track Electric Counterpoint, Fast 3 may be of interest to you . Also, Brian Eno's 'Apollo' album is amazing and would be a fantastic test for the V30, to explore it's dynamic range.
For female voice, I'll be playing some Kathleen Battle early on, to test how it handles her magnificent soprano ('Bel Canto' album on DG, track -'I Capuleti Ed I Montecchi: Recitativo E Romanza (Atto I): 'Eccomi In Lieta Vesta...Oh! Quante Volte''). Sticking to a classical theme, Fabio Biondi and his consort have done wonders refreshing the works of Vivaldi (Virgin Records). For accommodating scale and dynamics again, the Rene Leibowitz/RPO readings of Beethoven are phenomenal - the 3rd (Eroica) Symphony's Scherzo is taken at blistering speed. This has been remaster by Chesky records to great effect.
I have a bunch of Jazz I'll be trying, in particular Wayne Shorter's work ('Speak No Evil', 'Night Dreamer'), and many, many others.
Hot Chip is also super fun. Check out their tune, 'Night and Day' on their album 'In Our Heads'. While we're at it, most things by the soon-to-break-up Wild Beasts would be interesting. Their album 'Present Tense' is an offering of perfectly formed modern pop.
