I plan on putting together a system mainly for listening to music on my computer. This is my first time putting a system together so I'm not sure what components I'm going to need. In the end I want to have one sub (I was looking at the Velodyne DSP-12B) and two floor speakers (was looking at Athena AS-F2.2).
Are the speakers I was looking at good for what I plan on using them for? If they are what type of reciever should I look for?
Can't help you on the Athenas since I don't know them.
You don't really need a receiver since you can get radio over the 'net (at worse quality than FM admittedly). With that budget in mind, you could be looking at a NAD C325BEE or C352. These are fine performers and the 352 has a fair amount of power. There are many other brands of course and this depends in part on what your aspirations are as well as what's available in your area.
