Do you own both the Sine's and the PM3's at the same time??? If so can you provide a comparison?
I do. Ive put an update on the Sine thread here, http://www.head-fi.org/t/793518/audeze-sine-series/270 Didnt want to post twice but ill put an update on.
so i pulled the trigger and am now listening to the Sine. First impressions straight out of the box are im not sure... Im coming from PM3 so maybe spoilt but there dosent appear to be much difference. Bass seems more prominent kicks a little more and the overall sound, sounds a bit fuller more body to it, its hard to volume match but getting it close.
The Sine is detailed and matches the PM3 id say soundstage and seperation sound about the same, vocals are also very close. Bass definately more of it but i think the PM3 employs it better, maybe this will come with a good few hours burn in and become more controlled. I remember feeling the same about the PM3 when i first got them. Not too sure on highs sound about the same to me although ive never had a problem with them in the PM3 and wouldnt know what a rolled off high was.
overall the Sine sounds a bit quicker with more body where the PM3 sounds crisper and detailed but less if you know what i mean. Going to give them two or three days burn in with white / pin / brown noise mixed in with music and see how they sound then.
little update, after 24 hours burn in the bass seems to have settled down and is much less boomy sounds better overall as well, i found the word i was looking for to describe the sound the Sine seems energetic and the PM3 clinical, both have there good points but i just had a half hour listening and it was very nice and fun to listen too ive gone from not sure to Yes, a definate yes
