Here is my set-up. Im also a newbie and learned a lot from PDVD.
Im using my sony vaio laptop as source of my music audio output on USB plus a HTPC with Optical Out.
At first, I bought a DAYTON DTA-1 T-amp for 3,500.
I auditioned the Dayton DTA-1 in watts hifi in MCS plus I bought also the MIssion MV2 speakers for 5,500
I connected it on the laptops 3.5mm audio jack, It sounded OK but medyo bitin, Then after a week, I bought a Superpro 707 DAC for 5,500 which in USB mode can output 16 bit and in Optical/coax mode can output 24bit.
I auditioned the Dayton DTA-1 in watts hifi in MCS plus I bought also the MIssion MV2 speakers for 5,500.
Im very much happy right now with my Sound Set-up in my small room.
Total cost is 14,500 plus good wires and banana plugs.
