The E7 can't drive or is good enough for the Q701's. The E17 only just had enough power and even then the E17 had over 2X the power of the E7.
The treble "spikes" are more active in the initial hours.
You are sensitive to treble so I think you should make note of that. We here in the thread know that and know that your opinions on the AD900 and what not are just your favorites and subjective stuff but other people reading it will take it as actual fact..just a word of warning though. AD900/Q701/HD650 fit different types of people. And you should always or almost always make note that its your opinion and make note of any "differences" from norm you have like your treble spike sensitivity.
I don't like very bad treble spikes but if you can't even endue th Q701's then you must be much much more sensitive to them than I am.
Just watched ep 2 of Noir, again, decent, will watch to see how it goes, nothing happening yet.
Anyway... /random off-topic-on-forum anecdote.
