The R1N has some weakness, which you can not repair in amp or cable.
You will find out the importance of a PCIe Bridge and DDC, when you try it.
SPDIF-3 was the first that showed an improvement in the width of the soundstage and the black background. It literally turned the dac into almost as good as deltasigma performance in technicalities, without loosing the holographic experience.
R1N is not the usual DAC. Everything I tried before it in the chain, gave different results. It needs support, to collect the the music and help with the instrument placement. The soundstage is small, the instruments are too big…
This is where the DI20HE comes in:
1. Better instrument placement. Pinpoint them with ease in the stereo image
2. Balanced, levelled sound across the spectrum
3. Soundstage, the instruments are free to play there are a lot more room.
4. The most important is the time/rythm. Its just music, moving.
This DAC has for modules on two DA board, the same you find on the highend models(R8H3/R7H3). Get the point?
