Hi Folks,
A little bump for this thread because I'm close to pulling the trigger on a WA2 and have exactly the same question. I listen to mostly 20th century small chamber music as well as solo piano music and I thought the Q701's would work. I've been told, however, that they are not recommended with the WA2. So now I'm leaning towards the HD600's or HD650's.
Budget sort of aside, are they the best choices for my preferred genre?
PS
I posted my headphone/amp quest yesterday but put it into the wrong forum!
