Hey roysq,
The SPL Director is the exact same preamplifier as the Elector plus an internal DAC. Both are top-notch reference level line-stages and the DAC in the Director competes with seperate DACs I have reviewed that cost around 3K to 7K in it's performance. I believe the up cost is around $300 more for the Director. All the SPL gear, I also reviewed their amplifiers, is beautiful in their timbres/colors, offer 3D imaging, totally liquid/grainless in their overall presentation, and have great speed/dynamics. German build quality, yet are very reasonably priced. I put the combo of the Elector preamp and S800 amplifier on my list of the best components for the Stereo Times 2020 list.
