Have the Teac Amplifier bought because I was impressed by the reviews. Had two amplifiers with digital Eingänegn, a Cambridge Audio and Pro Ject. I have to say I was really disappointed with the sound quality of my Canton Fonum 601 floorstanding speakers. For a PC or Mac to inexpensive PC speakers, the amplifier may be good, but as a substitute for a "real" amp not. Too bad, it seems somehow to come not only to BurrBrown D / A converter to. Digital sound is in fact not always sound digital.
