Hi Wayne,just thinking outloud. as usual there are a lot of options so I'm just tossing around a few ideas. What would work nice is one multi channel amp so I dont end up with a rack in my living room. 6 channel amps are popular, 8 channel there are a few but not as popular. Perhaps a 6 channel and continue to use the plate amps for low frequency power. This isnt a tremendous issue yet since I'm still short a pair of 2405's. tweeters outside the box!
