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 besktop 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.
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 suggessions please.
