I concur: Electronic music is great for listening on high end audio systems. There are some pretty good recordings with great SQ from the following interprets/bands/groups:
Arnaud Rebotini, Bicep, French Kiwi Juice, Telefon Tel Aviv, Buscemi, Madrid de los Austrias, Tenderlonius, Plastikman, Kruder & Dorfmeister, Llorca, Future Sound of London, Future Sound of Jazz, Kraak & Smaak, Glo Phase, Minus 8, Lady Gaga, J.M. Jarre, Move D etc.
I've listed below some of my favourites. Enjoy and let me know if you need more recommendations
