I use it to power two passive Dolby height speakers on my 9.2 Dolby Atmos Denon AV Reciever. **Q: Does this need a pre-amp, or can it be connected to a DAC?** A: I've got this connected to a Project Pre Box S2 DAC which is connected to my PCs. This works well for me. **Q: which model would be best for AE 100 series, max 75w, min impedance 6 ohms plugged into an applemac mini** A: TPA3116 - only 19V power supply, so less than 50w into 6 ohm. - and no tone control. TB10A probably better, esp if you need tone control. The 24v power supply gives more ability to turn up the bass. Allan Hendry. MonoPulse. **Q: Anyone have problems with background noise from the v1.0g. i play a lot of classical as well as rock. i was hoping for complete silence when its on.** A: No problem with mine regarding noise.
