Ok, I got Qty.7 Audiosource AMP/1A amps comming in. I got Qty.4 Gemini CX1000 stereo electronic cross overs. I guess my 1st try at this, will be a simple passive Capacitor type xover from my mids to my tweets in my factory non-bi-ampable 3 way JBL s38 speakers, just because it is an easy way to try it more than anything. I figure at this point, I'll at a minimum be able to use the amps as mono blocks with the factory 3 way passive xovers in a more separates config using my AVR as just a pre/pro if I cannot get the speakers to cross as smooth as the factory integrated passive xovers. Any last minute suggestions with the experiement? I should be posting back in a week or so with my results. So I'll be using the AudioSource amps bridged, one to each 8" driver in my s38's, and I'll be using one internal Denon amp to each sets of mids and tweets. CHT-15 Velodyne Sub. Wish me luck, I'm going to need it. In thinking some more on this. I guess the first step will be to use the system for a few days with just the new amps and the passive xovers in the speakers. Then go ahead and do the true bi-amp'd test. So really three compairsons. Denon 4802 AVR alone with the passive xovers in the speakers. Denon 4802 AVR as the pre/pro using the new amps with the passive xovers in the speakers Denon 4802 as pre/pro with the electronic xovers before the amps, using the new amps for the low end drivers and using the Denon amps for the mids and tweets using the simple capacitor xover to the tweets. I wonder if my sub will be able to keep up with that sort of power though. May have to improve it somehow, if so, just another example of one upgrade leading to the need for another.
