Today I spent sometimes with the following setups in chronological sequences of usage:
XBA-N3+DP-S1 in balance mod
Sony WM1A + JVC HA SW-01 in single ended mod
Sony WM1A + JVC HA FW-01
AK70+JVC SU-AX07 + FW-1
I admit that is a lot of fiddling around in one day and perhaps after a long day of listening to music perhaps the later setup weren't as engaging merely based on fatigue causing lack of interest but I kept craving for XBA-N3 and DP-S1 setup.
