Just bought a CA/BA-F1 set and cannot find anything in the manual or sales literature that specifically states that the CA-F1 can be plugged into the BA-F1 using the DC input jacks instead of the AC input jacks. It would make sense that you can, given they were designed to work together, but it would be comforting to see it in black & white somewhere. Also, can you insert a 10 or 12 band equalizer in line between the CA-F1 and the BA-F1, and does that change which input jacks you should use on the BA-F1 [DC vs AC]? I have several candidate equalizers on hand such as the 12 band/channel Pioneer SG-9800, or the 10 band/channel TEAC EQA-3 or TEAC EQA-10, and finally the 8 band/channel Sansui SE-9 computer run equalizer. And same question pertaining to the AU-717 pre-amp/amp, inserting between the pre-amp and amp section as well as what would be the appropriate switch position [with or without caps]? I would prefer not to fry anything if possible.
