So that. And I emphasized system. Which in the not-so-lab-environment living/listening room actually includes all that unless it can be 100% shielded away. Mentioned "a" version was also about new small PCB's everywhere. All LDO's for the purpose ... N.b.: PSRR : Power Supply Rejection Ratio. Like "rejecting" 50Hz (60Hz) influence. Etc. etc. etc. ... look&listen 1 Lush^3-e Lush^2 Blaxius^2.5 Ethernet^3 HDMI^2 XLR^2 XXHighEnd (developer) Phasure NOS1 24/768 Async USB DAC (manufacturer) Phasure Mach III Audio PC with Linear PSU (manufacturer) Orelino & Orelo MKII Speakers (designer/supplier) Link to comment
