In non-balanced (Single Ended - SE) cabling the ground is shared between the left and right channels so some of the signal from the left channel may cross into the right channel and vice versa (at the ground connection on the voice coil of the transducers), hence why it's called crosstalk. Having balanced cables and amps ususally results in better separation and more output voltage. The extra voltage is advantageous power hungry cans, HifiMAN HE-6, but not so much for the less power hungry cans like the FostexTH900. If you amp isn't balanced then there no point to the cabling plus you amp may not have the output connectors that the balanced cable requires.

only if you don't start from zero. if you have the volume up too high to start with, it could damage the drivers...with powerful speaker amps, you're not going to get a lot of play with the volume unless you attenuate it with resistors. the robinette box or some system of utilizing resistors in parallel can give you both attenuation and also the proper load for your amps so they "see" the proper speaker-like loads.
to be honest, i don't know what the benefit is of using speaker amps for easy to drive headphones like the th900 or grados or denons, etc.
I was thinking I could opt for simpler life, sell my other headphones and get the TH900. My music library consists mostly of rock & metal, with some pop and electronic music in the mix; most of them are 320kbs mp3 and some FLACs.
My goal setup would be HRT MSII+ > Lovely Cube DIY amp > TH900, and for portable use Astell & Kern AK100 > TH900. Is there any sense in this?
