what dac/amp for multiple devices when computer is off?

I need for my new HD 58x jublilee headphone, due to arrive any day now, *maybe* an amp and or a dac too, if I really need one.
But I have a buying problem!

I have a nice computer with a creative soundblaster Audigy 5/rx card. the music plays well. I also have a Sennheiser HD 280 pro.

I also use the headphone for my iPad, television, a small form home theater system, [denon], a playstation 2, and even a boombox. *this* is my problem!
I see that many desktop amps and dacs are not only powered by the electrical cord; they are also powered in some way by a USB to the computer! Or is this "computer power" actually the sound input to the amp or dac?!

My problem then is that I do not have the computer on when I use the other devices! that is the crux of my problem!

If I buy an amp, alone, or a dac combo, I would need to be able to use this device on all of my other devices that play music too, without that computer being on.

Even that HELM AUDIO DB12 AAAMP THX AMP has a USB plug to power it, and of course, if my computer is off I cannot use it. maybe a battery-operated amp or dac is what I need; I *could* recharge the battery whenever i use my computer.
do I really NEED an amp or/and dac for my jubilee 58x. or even for my HD Sennheiser HD pro 280?

buying suggestions, please.

thank you,
freestone

If you look carefully at the specs, this one is actually has a battery:


  • Power supply: Internal USB rechargeable battery
  • Battery life: 6+ hours in use


For the battery powered DAC+Amp, there are some options from Topping, like NX4DSD

And I'm sure, there are others.


You can go to ASR forums and research how good or bad they are measured:
