I also have a Bricasti M1 SE DAC for my audio system. It runs direct into my Hypex NCore NC400 Bridged Mono Block class D Power Amplifiers. I am not using a pre-amplifier. The Bricasti M1 SE DAC is an excellent sounding DAC and I like mine very much.
The Prism Sound Callia DAC I mentioned above is for my video system using optical (TiVo cable box) and coaxial (Sony Blu-Ry player) inputs only (no USB input).
