Sounds great right!!
The key components that make this rig sonically so special are the VentureCraft DD LE OPA627SM DAC, and the Tralucent uber cable (which has great synergy with the 1Plus2 naturally) :-
VentureCraft 30-pin digital LOD
VentureCraft DD Limited Edition OPA627SM OpAmp pre-amp
Tralucent uber cable
Tralucent 1Plus2 (with Ortofon tips)
TBH..i don't like my self the sound of AK100+Alo Inter without AK100 (stock) being EQed. The International alone is a good amp. I prefer Alo Inter+ipod rather than AK100. But with some EQing, AK100+Inter is performing better than is not.
I have the original PX100's and I like them a lot. They do let in (and leak out) sound. Good for being aware of your surroundings IMO. I also have the Sansa Clip + (great combo)
AK100 + Alo International looks nice when stacked
