Firstly I must said that Asus has done a really good job on designing this unit for amp rolling because the screws were so EASY to come off and the case also slides off very easily. The op amps themselves were a pain in the butt to take off though and in the process I have bent the legs on quite a few of them
. I have taken the advice of previous posters and put them all on an adapter so it will be easier for me to change them again and again in the future.
To compare the sound of these 2 different op amps, I have been changing them back and forth with listening to the same song.
This is what I think of the sound differences and I hope those of you that also have the muses01 can tell me if you think the same:
At first I was really DISLIKING the sound of the Muses01 (still not liking them very much atm), I thought they sounded a bit less detailed compared to the stocks?? However, for some reason I also think that the stock has better sound stage, with more details. I could hear much more details on the little things such as the voice echoing in live concert songs. The Muses01 makes the sound feel like its closer to my ears than the stock.
I have decided to keep the Muses01 in for now because I want to see if I would grow to like them or not. If not, I am going to SELL them!!!
Oh yeah...and about the thingy behind the volume knob, unfortunately I have the B10K version too and I could also see the gain switch jumper next to it
but can not be changed
ps. I wonder if there's a way to check the authenticity of these Muses01, maybe the less sound stage and detail is because they are fake??
