My monos are currently on a rack (big rack, side-by-side), but that will change as soon as I have longer interconnects to the pre-amp - I'm moving them right behind the speaker terminals, facing the speaker inputs with the outputs. At 8" in length my speaker cables will become irrelevant (the IC will only be 6 feet max, so I'm not shifting problems from one wire to another).
Once I get all 4 monos for bi-amping, they will have to sit on top of each other behind the speakers.
Klaus - is there a way to get more/stronger vibrapods for the lower unit? I assume they ship with vibrapods appropriate to support the weight of a single amp.
