The RWA Isabellina HPA is a usb dac with headphone output and it runs on batteries. Right now Im using a laptop run off its batteries into a offramp run on a bpt power supply then into my battery powered Isabellina HPA. Im completly off the grid and it sounds great. Its a very good battery powered usb dac.
Netbook to USB DAC to Headphone Amp on Batteries
Are there any good DACs that I can use with a laptop or netbook, which are either USB powered, battery powered, or rechargeable for at least a few hours?
I am very happy with my Lenovo netbook for traveling, and have a spare 6 cell battery which means I can work and/or listen to music for most of the flight to London.
My Grado headphone amp travels easily and runs for hours on 9 volt batteries.
So all I need now is a good DAC?
Would the HRT Streamer or Musical Fidelity VDAC work this way?
Thanks for any ideas.
