I don't know about the Grand but a big part of what drove me to the Dali's was the performance at low volumes. These speakers don't need to be cranked to come alive, exhibiting a full, rich sound during late night listening sessions. Something very high on my list, though YMMV. Have you read John Marks Fifth Element review in Stereophile, where he coincidentally compares the Dali to the Peak Consult Incognito? Apples to oranges but instructive none the less. Good Luck.
