Non techie audiophile

Hi there, I am quite new to this entire computer audiophile world. Requesting your kind guidance. I am currently using Synology DS214 Play -> Gigabyte brix (Windows 8.1 with JRiver) -> Ayre QB-9 DSD -> Accuphase Amp -> Harbeth Speaker combination. I have a few DSD files as well. I am not happy with my current setup. I was looking for a good Audio server for my setup. I heard SotM Audio server with Singapore dealer and it sounds amazing. But it is too expensive. I tried to buy the SoTM USB card but my Gigabyte brix does not have a PCI extension. After reading this review I am trying to understand 1. If I use this SoTM mini Server in between Gigabyte and Ayre then will I get similar sound to SoTM Audio server? 2. Or should I install a LMS in my Synology and eliminate the Gigabyte completely? How can I get a better sound (ability to play DSD as well) with convenience of control from iPAD? Thanks.
