Balanced tube amp for $600... might have to think about this one.

You have to buy an after market cable or get one built for the grado's. AFAIK no head phones come with balanced cables OOTB. With the 4 pin XLR on this amp the latter is likely. Not many amps using this novel connector(yet). Balanced simply means one cable and connector dedicated to each driver, The difference being in the design of the carrier (XLR) as having separate lines for +,- and ground, hence three pins. Single ended lumps the negative and ground terminal together. Not the best way to do things but more than good enough for short runs of cable. Balanced circuits run at +4db while SE are at -10db. One advantage to balanced is length of cable is not an issue, it's the same performance from 1 foot to 100 .
As for the function of the MK VI I'm not entirely positive that it could function as a pre amp but I don't see why not either. It's in keeping with LD's philosophy for the MK series amps. Dual function as head phone amp and if you like a *pre amp for the main rig(s). *provided your gear has balanced inputs of course.
Hope this helps a little. Sorry it took me a few days to answer, very busy these days
We'll have to wait for an official review for the concrete details...I'm on this amp like icing on cake if it's less than 700US shipped. Tube rolling/cap upgrades should make massive improvements in SQ if the iron in this amp is up to snuff. I don't think Sword or David skimped in this critical area. You can get away with mediocre caps and resistors but not mediocre output and power trannies.....my 2 cents FWIW.
