I am seeking information in regards of the sound of the Sharp GF-777Z I read here a ways back that the JVC RC M 70 has more sound . Thank you 

Sharp GF-777Z has more sound 'bass'

JVC RC-M70 has Better sound 'better seperation'

The m70 sounds way nicer than the 777 but the 777 looks better!
All depends what your after out of a box, if its sound my advice would be the m70 all day long

I'll Second  the above statement  

and I'll add, that the 777 is way more complicated ( thus more to go wrong with ) to operate than the simpler & Robust JVC RC-M70
