I use an apple tv the Brennan is a nice bit of kit but you could have greater flexibility with somthing else
I ripped my CDs using a my laptop the libary is held on my nas and the apple tv holds a copy of my ITunes libary too. Back up is king. As the libary is sat on my nas I can access it from any number o streaming devices sonos, squeeze box, ps3 etc you will also find many av amps are dlna compilent ( a friend of mine just bought an onkyo amp which will stream spotify and will read his nas )
If a standalone unit such as the Brennan is exactly what you want / need go for it and enjoy - if you want a little more the world is your oyster for not much effort!
