I've always considered the Speakers to be the heart of a system and the preamp the soul of a system. You are asking one of the most subjective questions out there and everyone is right, they found what is right for them. Your taste, your emotional envolvement in your music and even your personality can shine through your system.... We can all give recommendations, but in the long run, you have to do this one.... I use a Coda.
