- Umm. I'm not so sure on this one. Digital preamps for DAT and CD make a lot
- of sense as the switching, volume control, balance, and special effects
- can all be done in the digital domain. However, one must make the switch-
- over to analog at some point as music is an analog phenomonon. Digital
- circuitry is designed to operate a moderate voltage low currents. However,
- transistors and ICs for power amplification operate at high currents and
- power dissipation (sp?). I'm not sure that I see any benefits to a digital
- amp as I would think that DA conversion has to occur before current
- amplification. Any takers?
