Amp/Preamp Asylum Looking for a new Amp or Preamp? If you're after tubes, post over here. |

Just for grins....The Jackery 1000-Watt/Hour portable power station is capable of supplying a 120-VAC 60-Hz pure sinewave and will power my entire audio system (except subs) for nearly 18-hours.
Jackery is powering: Mac Mini Roon Server. Eversolo DMP-A8 Streamer/DAC/Preamp. NAD C298 Class D Amp.
My audio system with the Class D amp draws an average of only ~50-Watts at normal listening levels.
This model weighs 25-Lbs and will power other devices out in the field or during a power outage.The Jackery can be recharged at home on an AC outlet, 12-VDC car outlet, or solar panels. It will run my wife's CPAP machine overnight, twice, with power to spare.
