Questions regarding Sunfire Cinema Grand setup

I just purchased this amp, and I noticed I have the choice of hooking up the L and R mains as Current or Voltage. It is my understanding that the Current setting, will provide a more "tube-like" sound, which intrigues me. My concern is that I don't have this option for the center channel.

Does anyone know if I use the Current settings for my mains, would it sound strange for home theater, since my center speaker would be setup as Voltage.

I am assuming that it was designed this way because in a movie setup, you won't notice the difference, whereas in two channel, you can go with whatever setting you like better.

Does anyone have any real world experience with setting this amp up either way?

Thanks
Greg

Greg,

You are mistaken, all the current Sunfire amps have the current and voltage source outputs only for the front left and right speakers.

I used a Sunfire signature amp in my home theater setup...I tried both ways and I could never tell the difference in the home theater application.

I owned the Sunfire Cinema Series II and ran it both ways.. for movies you can't tell the difference even with a $7k processor. So pick which one sounds best for 2 channel and don't worry about it.. the sunfire amps don't offend but they are not the last statement in resolution or detail. They are perfect amps to put into an enclosed space since they don't generate any heat and auto turn/off with signal sensing..

If you can figure out a way to bi-wire your speakers, that is the best solution, IMHO.
My speakers were bi-wireable and I ran the Current to the mids and up, with the Voltage to the bass. Sounded great. I agree with the previous posters - you really shouldn't hear a difference with the center channel on a different mode than the mains - my results were that Current was more involving for the mains.

Thanks for all of the advice. Fplanner, my mains can be bi-wired. My binding posts on the Monitor Audio GR10 don't indicate which set is for bass and which set is for mids and up. Is there a right way and a wrong way to bi-wire?

Thanks
Greg
