I don't need 2400 Watts but what about the DSP?
I have tried the EQ/DSP on the RBH SA-500DSP. I end up not using the EQ/DSP on my RBH SA-500DSP Subwoofer amp. I just use Audyssey Dynamic EQ and bypass the SA-500DSP's EQ/DSP.
I think Audyssey's Automatic Subwoofer EQ and Dynamic EQ do a great job.
But for guys who are into speaker measurement and manual EQ, I think the EQ/DSP could be useful for tweaking manually.
I am not into manual EQ/DSP tweaking because I absolutely love what Audyssey Dynamic EQ does for my subwoofer bass.
In my living room, the Denon AVR-X3100 does the EQ, then outputs to the SA-500DSP (EQ/DSP Bypassed), which powers the two (2) SV-1212N subs.
For my HT room, the Denon AVP-A1HDCI does the EQ, then outputs to my ATI AT3005 amp, which powers the five (5) SX-1010 subs.
