Mribob, congratulations on your purchase. I haven't used the advanced music servers of today, but I have been using a computer based network music players for some times. The first network music player that I bought was Roku, which really wasn't good sounding. Now I have iTune on Airport. I liked it a lot. I would set it to random play, and let it play hours as a background music. I would use my laptop to quickly find the song that I want. I was using a upsampling Musical Fidelity DAC then, and the sound was pretty good. For a while I was exclusively using the network music player, and put all the CD disks in the stroage.
Then a couple of thing happened. I started to experiment with high resolution format. I started collecting SACD and DVD Audio. Unfortunately there isn't any solution when it comes to high resolution format. The digital data cannot be extracted to the computer in the raw format for later play. In order to use high resolution format I had to go back using the disc player.
Also, the price of storage medium came down a lot in the recent years. Back then when I first copying the CD to my computer I used 128kbps bit rate. The storage was still fairly expensive, and I didn't want to invest too much on the storage. When I moved to iTune I then started using 192kbps. And then the storage price kept falling, and I eventually moved to 256kbps bit rate. Looking back, I probably should have been using lossless format all along. But the storage was expensive, and I really didn't want to spend too much on gigabytes of storage space. Now the storage cost has come down quite a bit. You can get a terabyte of fault tolerant mirrored disk system for under a thousand dollars. But now I don't want to spend hours and hours to re-rip hundreds of CDs, especially when the high resolution format is still out of question.
Nowadays I occasionally use the network music player, but in most cases I just pop in the CD / SACD / DVD Audio to the disc player when I listen to music. I see the convenience and other benefits of using the music server. I'll probably want to experiment with it in the near future as well. If you end up getting a music server let us know how you feel about it.
