I agree but it would still be good to hear the comparison; it's similar to saying (like above) "the Gustard R26 may be equal to components in higher echelons of hi-fi"; while it shouldn't; there has been some promising comments that it could be flirting with components twice-three times it's price. Like the above review between it and the Denefrips Venus but more info and time will tell.Price wise- it is an unfair comparison, but the basic technology and general direction--R2R, FPGA, I2s input, External clock input is very similar. The audio-gd HE line is stunning and may be equal to components in the highest echelons of hi-fi (like 20K and higher dacs)- but they are so big- and so heavy. Just to much for a headphone system.
For sure the Audio-GD is serious gear and has a large foot print (really well made) that caters more to big rig set-up's where footprint concerns take less of a priority. The R28 headphone amp/DAC/analog preamp is also big compared to the RME and Burson GT but the Audio-GD R28 stays and the others are destined to secondary rigs; the RME is cute, well designed and does have it's own plus's but the R28 R2R is preferred and hence very curious about the Gustard R26
