Yeah Ray, audio engineers have known for many years how to make amplifiers which amplify with audible transparency. One of the great things about the modern audio scene is the availability at very modest cost of receivers which are audibly flat from 20Hz-20KHz along with inaudibly low noise and distortion. Nothing audibly better than that is possible, regardless of cost. These days no competently designed unit exhibits a sonic coloration(i.e., a "sound").
