Good headphone amplifier

I have Audeze LCD-XC headphones. I drive them with a couple of DACs, but the one I like the best is my Benchmark DAC1. You can find newer versions of the Benchmark (DAC2, retails for $2K) pre-owned for around $1K. You'll need to look hard to find better, more transparent sound.

If you can find an Auralic Taurus Mk2 amp you would be doing well. I like the Auralic to the point that it was the only original component I kept as a spare to my Moon 430 ha amp.

Thanks for the suggestions. 

I use an Ifi Ican Pro with my LCD2s. I like it because I can use the solid state mode for better high frequencies, and tube mode for more liquid mids. You can boost the bass and it has a 3D mode (crossfeed?) which I don't use. It is also balanced or single ended. There is one on this site for $1,200.
