Sansa Fuze V2 (RB w/LOD patch) -> FiiO LOD -> NuForce Icon Mobile (low gain) -> MEElectronics A151 (Comply T100's)
Used this table to set-up my Rockbox EQ settings....http://www.independentrecording.net/irn/resources/freqchart/main_display.htm
Really helped me difine a sensible 5-level EQ scheme. Here's my settings...
Low Shelf Filter:
Cut-off = 60Hz
Q = 0.7
Gain = 0.0 dB
Peak Filter 1
Center = 160Hz
Q = 1.0
Gain = 0.0 dB
Peak Filter 2
Center = 1000Hz
Q = 1.2
Gain = -1.0 dB
Peak Filter 3
Center = 4000Hz
Q = 1.0
Gain = -1.0 dB
High Shelf Filter:
Cut-off = 12,000Hz
Q = 0.7
Gain = 0.5 dB
I keep base and treble flat (0 db), and adjust "Gain" on the Graphic Equalizer to get the right amount of low's, mid's and high's for any set-up.
Rest of my Sound Settings:
Chanel Configuration = Custom
Stero Width = 120% (have tried higher, but won't go above 150%)
Crossfeed = Yes
Direct Gain = -3 dB
Cross Gain = -7.5 dB
HF Attenuation = -15.0 dB
HF Cut-off = 1300Hz
Dithering = Yes
Time stretch = No
Compressor Threshold = off
Make-up Gain = off
Ratio = 6.1 (don't think this matters when threshold is 'off')
Knee = Soft (don't think this matters when threshold is 'off')
Release time = 700ms (don't think this matters when threshold is 'off')
My Crossfeed settings are in the middle of the adjustment range. Crossfeed is supposed to help iems sound more like "open air" listening in which the left ear can hear sounds from the right channel and vice versa. Should reduce fatigue and produce more natural sound.
So far so good, love the sound over default firmware.
