I currently own a Denon S650H model and not happy with the clarity on my speakers. Nor sure if it's my Tone settings or speakers. I use Audessey and wanted to fine tune it with the editor app but it is not compatible. Should I upgrade my receiver to get better sound clarity or speakers? I currently use a pair of 3way Bookshelf Speakers from Sony (rated at 6ohms). Used these speakers with a Yamaha receiver and it sounded good . I mostly listen to music (70%) and 30 % movies. New to this world of audio so any suggestion would help on how I could fine tune to get more crispness in sound. Thanks a Ton ! In advance
