Marantz 5014 avr vs marantz 7706 processor

I am using the marantz 5014 avr for 3 channels and preouts connected to a McIntosh amp.  Is their 7706 processor going to improve ht sq that much?  I am used to marantz but maybe another manuf should be considered?
The 7706 processor is going to have a much better power supply and better layout for the DAC and discrete analog output stages.  The result is better/stronger bass and an overall smoother sound.  It will still have the Marantz sonic signature which is full sound with a soft / rolled off high frequency.  If you like this sound, then 7706 is a good choice.  If you want a different sound, then you should look to a different brand.
