Small, bright room; listening levels are low to moderate; 90% music use; latin dance music, classical, jazz, easy listening. Aperion 5.1 system (10" sub) or Rocket ELS? Why? The reciever will almost certainly be an Onkyo 601. Thanks. BTW, anyone know if it's possible to get the Rocket ELS with two 2.1's replacing two of the LRS satelites?
