@audphile1 "That's bad form". Good one! Bad form is doubling down on a useless post. I left out " (it’s not RP1 cause it’s pretty transparent) and or your room acoustics are bad or all of the above."
Are you saying that the room acoustics came in to play only after he switched to the RP1? He could distinguish between dacs before he switched. Look at @thegreenline post above as a logical explanation. It appears that being called out is bad form to you.
