I doubt that this will change the impression of the SQ. SR-71B is a neutral powerhouse. What comes out of the source into that amp and out of the headphones will not sound any different in terms of SQ. When I bought my SR71b it was purely because of the need of power, the SQ is exactly the same.
I guess the comparison could be interesting if comparing headphones being driven balanced; AK120->SR71B->Balanced Headphones vs AK240->Balanced Headphones.
It's still comparing one source to another. If I had a pair of HE-6 and wanting to go portable this could be interesting...
