Hi there,
As an introduction the HE-6 are very difficult to drive and obviously the price factor is changed because of the amp + adaptator needed.
I confirm that ODIN and HE-6 have similar signature, good bass and clear trebles but better textured with the ODIN where on the HE-6 they sound airy.
Considering the amplification side, actually the ODIN is a clear winner but price is twice.
