this is my 1.5 months burn-in impression:
this is my setup>
dac: da8 & m7
head amp: audio-gd m6
headphone: hd800 , he6
computer: 6 years old toshiba notebook, and desktop: 1 year old amd 4 cores . ram : 8 gg.
dsd recorder: korg mr-2000
software: foobar , jriver, and hqplayer.
this review will be focused at cas and dac part:
maybe i am get used to the sound of audio-gd master 7, at the very beginning , i would take 1 week burn-in da8 for comparsion.
and i really wanted to sell da8.
first 2 weeks , i mainly used jriver, and toshiba notebook . and the sound was dry, slow, weak,
3rd week, i changed to foobar and the same notebook. it is improving but i still wanted to sell it.
4th week, let it burn-in, and enjoyed m7.
6 th week (last night) , i changed to desktop computer , and hqplayer, and the impression was; wow!!!
details, wide soundstage, punch, speed , control, all come back.
software good for da8 : hqplayer > foobar > jriver.
this desktop powered m7 and da8 pretty good, much better than 6 years old toshiba notebook.
1st 1 -2 weeks impression may bring you miss a good dac.
the downside is the treble, the m7 crystal clear treble is impressive, da8 at this part is fall behind.
i am thinking to change fuse to improve it. i also have the similar view wtih brunk :
"It still lacks the detail and resolution of the m7 but it gets close "
price tells the difference . this is face.
