I have a Technics SU-7300 stereo amplifier and was thinking about connecting it to my SDA II's, while my 805 acts as the pre/pro. I was about to disconnected the subwoofer in the living room from the amp when I saw a knob on the back of the amp. Above it, text is there that says "ground". Right above the knob, it says Left/Right. Does that mean the amp is not a common ground amp?:confused: I just want to be sure that if I try this, I don't end up exploding my SDA's.:eek:

    Take an ohm reading across the negative speaker ground. AFAIK the ground switch only "lifts the ground kinda like a cheater Plug.
    Please. Please contact me a ben62670 @ yahoo.com. Make sure to include who you are, and you are from Polk so I don't delete your email. Also I am now physically unable to work on any projects. If you need help let these guys know. There are many people who will help if you let them know where you are.
    Thanks

    Nevermind. I just realized it said GND, not ground, and it is right next to the Phono input. duh.gif:o:D I'll be hooking up the amp in a bit and will post the results later.:)

    And I've had this amp all this time!!!!:mad::D

    I'm making room on my armouir.:p The PS3 is going vertical in the middle.:cool: I'm thinking a 2' BJC stereo cable for the connection (I only have a Monoprice Premium cable connected for now). Will that make a nice difference? Any other suggestions?:)

    One and the same, but you're right, it is for the TT.

    Oh yeah, I understand, it's just that as soon as I saw it said GND, not ground, that reminded me it was for the Phono input next to it:D
