Guys, i set out to get the RMAA results of my Fuze (Rockboxed) vs the setup Fuze>10uF Vishay Caps>Mini^3, mainly to see if the caps in the chain were causing some of the notorious behaviour....Basically, sometimes when i plug in my RE0s into this setup, something irritates me. To find if my setup was making some HF noise, i performed RMAA, these are the results. Couls someone please help me read these, as in what might be very wrong here?
These are not real world tests, i mean there was no splitter cable and headset/load attached.
My testing device is an Intel HD Sound Card on a Dell Studio 1555.
I like the way my Studio 1555 sounds though, but something about the setup isnt right. i dont know if its the capacitors, i have ordered a few Nichicons & Silmics. The problem sure is not with the RE0s, i like them a lot out of my Computer (Studio 1555), and not that much out of my Rig. its like they become more sibilant. And i dont have a clue if i dont like the Mini^3's sound, or the Fuze's sound itself.
Help me here guys.
Regards
Edit: Ofcourse the Fuze and the Mini^3 were never Volume matched.
