APL NWO-1 is the unit custom made by Alex Peychev at APL hifi.
It starts out life as the Esoteric UX-1 universal player with everything else removed except for the transport . The rest ( master clocks, upsampling, 10 AKM DAC's per channel with 6H30 class A tube outputs.
Interestingly, the Spectral SDR 4000S aslo starts out life with Esoteric Transport( P3) but custom built DAC discrete output stages by Keith Johnson.
Both are incredible sounding machines. I prefer the APL NWO-1 but I do own both units.
