I am upgrading my audio system shortly and am undecided as to whether or not I want to change the head unit. I currently have an Eonon D5102 installed, might want to change it to a Pioneer system.

A couple of questions regarding the RCA outs of the Eonon - I see the only pre-out they have listed is for a subwoofer, is this a full-range signal (that you can plug for example a 4 channel amp into to power front speakers and a sub) or is it low-pass filtered?
If it is a full range signal, is the Eonon's output satisfactory? I read somewhere that the RCA pre-outs are 1v compared to a usual 4v or so on a Pioneer deck. I'm not an audiophile, I'm spending about $800 on sound system, will this make any difference?


Thanks.
