Wow, thanks for all that info Al! That's a good point you bring up about impedance (something I know nothing about). I'm swapping out the S300 with a Belles 150A v2 Reference, which is 100k output input impedance, but that would still result in a total or just over 9k -- still too low compared to the recommended 20k+ load of the Symphonies.
Then again, I've been using the pre with my 10k S300 with great results. Or maybe I'm missing something and I just don't know it.
I would like to use the RCAs since I bought the ACI 60hz high-pass filters to ease the low frequency load on the amp, which is something I'd like to do since my new amp would generally considered a little underpowered for my notoriously demanding Usher BE-718s at 125 WPC.
I will just try both methods and see what works best!
The subs have 2-prong ungrounded plugs.
Question: can I run speaker level inputs from the speaker's binding posts to the subs? I'm running a shotgun pair of speaker cables from each binding post on the amp to the speakers and would rather not add a third cable to each binding post.
