You have an excellent value system, I recently built myself a budget system revolving around the Totem Hawks, and the Rega Mira 3. I am using the same Blue Jean Belden cables as you are(but upgrading to Totem sinews and trees).
I store all my PC using FLAC format (My PC is used as the control center). It is just so convenient. I am searching for a quality DAC at the moment.
I am a classical music nut, since I listen mostly to chamber music, my current system does the job very well. But when I play orchestral, my system's many deficiencies are revealed. But the sound is still more than good enough to be enjoyable.
