Donny i am not a singer , and did a lot of tweaking in the past that improved the keyes , but yet i was limitted to the basic souns , you can not change FORD to become BMW 'you can make it better but to a certain limit.
at the end it is a matter of taste , if you enjoy your EA7 good for you , i enjoy my GENOS ,for me the sound quality is the most important and I am willing to make an effort even if the operating system is less comfortable , though in my opinion it eventually gets used to every operating system, and ultimately if the organ rings well it is most important to me.
