Naim owner since '92 with original 72/180 ("it was like looking into their souls"),
progressed through cd3, hicap, cdx, 82, cds2, supercap, 52, 135s, nat01...

now fully digital, overcoming a few bumps on the way to get it making music and stop sounding nasty.

- uniti Core and nDac/XPS-DR at the front end with Hi-Line (SuperLumina & ND555 in my future?)

- 52 / 135s still make great music and show through any change at the front end

- Epos ES22s on Naim Chips (minimal crossover, expressive, just make music and very hard to replace...)

Optimised setup to lower noise floor and let the most music through:-

- dedicated spur for the music system

- brain, brawn and digital stacks

- fibre Ethernet to the music system, TP-Link MC200CM fibre media converters with Naim end on TP linear PSU

- music on USB drive powered by TP psu

- top-level router and switch on screened isolation former and ferrites++ to keep mains clean

- noisy house electrics on screened isolation xformers with ferrites++, or SMPS powered off when not in use 

- farady shield screening, to keep wifi out of mains feed and system



System Details

Uniti Core +USB drive, DAC/XPS-DR, HiLine, 52/135s, NACA5, Epos ES22s.
