Thanks for all the feedback. The 7500 sounds like a good power amp for the 1.6's but you all seem to be looking for a little more power for the mains. Has anyone tried the Sunfire amps? I saw on the web that Sunfire recently sold and the chat room chatter is that people seem very upset at the company who bought Sunfire and their plans to move production overseas for the sake of cheap labor. Their also closing down their repair facility. All that said, the Sunfire amps seem to be a good fit.
