After the very little experience with HT/multichannel hi-quality reproduction I'm doing with my new M system, a question starts making space in my mind.

For quality reproduction (say multichannel DVD audio) , what is the best budget balance between front channels and surround channels?
To simplify things I'm assuming the system does not need an LFE
Given 100 as total budget for channel investment between
FRONT, CENTER, SIDE, REAR,
what's the balance you think is giving the best result?
25,25,25 and 25?
or
45,25,15,15?
or
50,25,0,25?
or
60,30,0,10?
or a different one?

My limited listening experience is telling me that front and center are the most important and must act in perfect sinergy (same crossovers, same amplifiers, same speakers) and rear and side speakers must have first of all a timbre similar as much as possible to front and center but they can have less extention and less power.

It will be very interesting for me to know what other more experienced listeners discovered with time.

Thanks
