Hello
I am not sure this is the right forum for this question (if so please let me know) but anyway I recently upgraded my nuforce ref9 from v2 to v3 and doing so ending up with the 2 old amp boards that are really good so I thought to build a amplifier of them for my brother. So I have been searching for the Input Voltage on these boards for pairing them with a proper psu/smps for this build. So does anybody have a clue? A 11 year old post
http://www.audiocircle.com/index.php?topic=17913.420 are saying that they are 52V (but it feels like it is preproduction discussion).
Regards
Johan
