New Sunfire Symphonic Reference in the house . Important question?

Options
I bought a brand new sealed in the box Sunfire Symphonic Reference Load Variant High Fidelity Stereo Power Amplifier today at an estate sale. Hooked it up today to my garage rig to test it out. Very powerful strong sound signature. My question is this. Currently I have a Sunfire 5 x 400 amp powering my front SDA monsters and two of my LSiM702 surround speakers. I need a certain amp for the big SDA’s. A common ground amp. I am planning to use the Parasound for center LSiM706. The Sunfire 5x400, one channel was blown when I bought it. With the four LSiM 702 surrounds and use my brand new Sunfire 2 x 250 with my SDA’s. Are all Sunfire common ground amps?
As always. Thank you. D9etakpwby5vp.jpeg

    It is common ground, but it is lacking for power to drive the SDA's with a sound you will enjoy. I had one and I could not move on from it fast enough.

    From the specs:

    "250 watts rms per channel into 8 ohms, from 20 Hz to 20 kHz with no more than 0.5% THD

    500 watts rms per channel into 4 ohms

    Outrageously low -115 dB Noise

    An enormous power source provides the ultimate muscle for limitless dynamics

    Peak-to-peak current output capability is 80 amperes per channel

    The amplifier can drive almost any load to any rationally usable current or voltage level."


    250wpc into 8ohm and 500wpc into 4ohm isn't enough power?

    Not the power as much as the sound it produces. YMMV, but it was not my favorite amp.
