Im not sure if i should buy it. I got the audioengine d1 and waiting for my hd6xx to arrive in december. will it be of a benifet for me or should i just stay with the audioengine d1 as an headphone amp as well?
I am in exactly the same position as you. got a slightly cheaper dac/amp and have ordered the hd 6xx. I am thinking about getting a dark voice tube amp. I know its way more expensive but apparently it pairs insanely well with the hd6xx. I would save for a tube amp or just continue as you are. Of course this amp will make a difference but a tube amp with the 6xx/650 is the way to go in my opinion. (I was just about to buy one of these but decided not to)
Thanks for your advise. lots of thinking to do before deciding. i might expend and make it a collection and i might add a tube amp further down the line, and i heard this amp is a must in every collection anyways.
