I went from R2R-11 to R1, then i managed to compare a Master-11S against Hugo2 TT + Mscaler and bought the M-11S... and now I am a happy owner of the R7HE.
I've heard some decent Chi-Fi DIY gear like XiangSheng DA-05B (dual AKM4497 and i fitted a WE396A in the tube buffer, upgraded the OpAmps to full set of Burson V6 Vivids ) and have extensively auditioned the Chord Dave + BluMscaler at a local dealer's place with their obscenely priced speakers...
but I keep coming back to my AGD gear with a smile
How did you find the Chord Dave against the three times cheaper R7-HE? Did you have the chance to compare them side by side on the same system?
I have Audio-gd R8 DAC and the M1 preamp with a pretty decent hi-end system with all the electronics from Asia (Audio-gd, Gustard, Line Magnetic and SOtM) and I've heard +100k and +200k systems that were worse than mine, and that was before several good upgrades I did on the last weeks. There are a LOT of hiden gems in HiFi from Asia.
