when i talked with kingwa: ( we are speaking the same language), he said
re master 5/6 : head amp is bonus. what we paid for is the pre-amp.
master 6 can drive any easy or hard to drive can. but in fact my es10 i set 8-10/70 is ok to listen.
after around 200 hrs burn-in, my impresson is you will easily find out which album is good recording, no bargain.
and more details i can get in which previously cantate 2 can't provide.
when i listened to RUSH-MOVING PICTURE , didnt feel noisy, I set DT880 to 30/70,
Now, high-mid-bass is very neutral and harmony, i won't feel any part is too much. and of course
the horsepower is so strong.
forget to tell you, dt880 is single end only, later on, will mod it to balance. and change another power cord instead of fty power cord.
