when size is no matter anymore...here's my another lovely 3 stacks setup...
IPC (wav files) + Fostex HP-P1 as DAC + ALO MK3plus + Beyer T1
looks like a real men's rig..heh..
iBasso DX50 > Onest11 Pure Silver 3.5mm Interconnect > JDS Labs C5 > 8N SPC Mini-XLR to 3.5mm Headphone Cable > AKG K240 Mk. II
Sometimes..a cable can really make the difference between an amazing sounding rig, and an augasmic sounding rig.
Sorry, not so portable ! let's say... transportable : RWAK100 + TU-05 + TH900
Recently I added and some damping material at some strategic places
and also added on the back an XLR (NOT balanced) plug, just because the 1/8 jack is Sooo fragile (OK it was not so easy because it's crammed inside).
