I do agree that a good set of separates is probably overkill for the SBS-01s, unless you are planning on upgrading the speakers soon. So an AVR is a good compromise and if you decide to go that route, all you would need to add is a pre/pro or new receiver later on. Receivers do tend to come out every year and have more features, but I don't tend to buy a receiver just on features alone, as I don't usually need all of the features that they provide.
