This summer I will be looking to upgrade my system. I am strongly considering an Fi product, but I do not yet know which one. I guess my question is what the minimum and maximum power you would suggest running on the SSD, Q, and BL. I would not be purchasing a BTL due to power requirments. I certainly do not want to blow a new sub, but I do not want to underpower them either. So, what is the power range, as well as optimal for each of the three? Thanks
