Definitely try computer audio. If you want cheap and quick - try Slim Devices SqueezeBox Duet. If you want higher fidelity, try the Slim Devices Transporter. If you want better convenience (and no need for computer) try Sonos. If you want some of everything, investigate Apple TV and a DAC of your choice. If you want best fidelity get a computer and an asynchronous USB DAC such as Wavelength or Red Wine Audio or the ModWright Transporter.
Yes, these all get progressively more expensive and yes more, different and "better" are always right around the corner. Which is why the Duet is a good, inexpensive place to start.
