If you own Vandersteen speakers, I think the Vandy subs are a better choice. The Vandy subwoofer uses a special interconnect between the amp and the sub which provides the ideal interface with Vandy main speakers. On the other hand, if you do NOT own Vandy main speakers, I think the REL is a better choice. The REL Q201E, for example, has two connections from your preamp: one for music, and one for LFE used in home theater.
