Looking for a Quality Desktop Solution

Get a KEF LS50 and put the speaker behind you like I do. Putting speakers on a desktop is not very satisfying. I know I did that as my main system for 5 years. 

You actually have tons more choices if you exclude the desktop. If you do use the desktop, then you can save a ton of money to get something like this. You will not need the Hegel then.

KEF Powered Desktop Computer Speakers

Here is an example of what I mean.

I use Totem Mite speakers and a small Matching sub on the floor. They are beautiful and sound terrific near field. Natural and detailed. You must be very careful in a desktop situation not to have a noisy system or harsh  speakers.

This could work for amp.  Plenty of $$ left over for nice speakers.

There are a pair of Quad S-2 over on usaudiomart for ~$1K. I had the S-5 model for about a year and rue the day I sold them. Still looking for another pair until this day. Might be a good solution for the recommended "Behind You" config.

On a desktop in the near field I think the KEF LS50 concentric driver topology makes a lot of sense. If you get the powered version you might be able to just plug in your Ethernet or streamer and be done. Best of luck.
