Hi. You may be the answer to the holy grail I seek!

I notice from a few threads I've read, that you are the proud owner of the Little Dot MK III and Darkvoice 336i. Now, I was all set on purchasing the LD MK III until I came across the Darkvoice. Now I'm finding it hard to decide which amp to plump for. I want to make a purchase in a couple of days. My headphones are beyerdynamic DT 231s. Which of the two amps would you recommend I match with them? Oh, by the way, in case it helps, the rest of my setup is iTunes/iMac (source) and Beresford TC-7510 DAC. I want a valve/tube amp to finish my little budget system off. Any advice would be most appreciated.
