I have an older firmware version that I haven't bothered to update as it works well as is. I'm always leery of 'updating', ha!

I keep it simple. I use my AA daily in my kitchen - mostly for WebRadio through my older Toshiba Vista Laptop; however, for music I have over 800 tracks on a USB that I ripped at highest resolution from my collection of CDs. Really easy to use this way.

Despite having a couple of M3s on board (I have a pair also), this unit really is not meant to replace a larger system in a big room. I mean who places 2 decent stereo speakers 6 inches apart? The AA works very well for what it was designed to do IMO.

I thought that it was worth the cost...
