knowing the hd 700 is 150 ohms, itll sound pretty bad unamped. im guessing sterile and harsh with an odd veiling of detail, thats usually how it goes. very bland sound.
anyways sounds like the WA3 will be a winner. it'll last forever too and you can play around with tubes later.
So do you think the wa3 will outlast a bottlehead crack? Is the extra price justified in your opinion?
