Updated – Gold Note's compact PS-10 4-in-1 streamer, headphone amp, preamp and DAC gains the Plus version. Aside from replacing the Bluetooth antenna with a 3.5mm stereo analog input, it also beefs up its internal power supply. A further upgrade path is the new PSU-10 Evo external inductive power supply with dual chokes and multi-cascoded transformers which connects to the PS-10 and PS-10 Plus units via 8-pin Hirschmann DIN-terminated umbilical. "Instead of simply enlarging the internal power supply or making it dual mono, ours creates the ideal AC filter to enable the connected component to sound its very best."
