I own the PM3 and tried the open back Sine DX. Love my PM3. Most audiophile folk go for the PM3 sound even tho it pulls back on the treble bite in trumpets a bit. So on the mellower side but not as dull as the NAD HP50. "Dull" exaggerates to make my point. While the Sine DX seemed to fit descriptions and specs I'd seen for the Sine, which is a more forward treble, hence plenty of bite in the brass and would certainly bring out a sense of clarity in lyrics because the consonants would click and ting clearly on female vocals.
While different in upper sound signature both slam pretty hard on the bass when called for. Ray Brown on bass all day long, my friend.
Now in isolation and in comfort, easy choice of the PM3. Cups ease around the ear while the Sine is built to press on them. The Sine will require you to be patient as you find just the right way to wear them for your head, and you may well stretch on the headband to get your own best fit. However, Sine smaller earcups make Sine more easily portable.
Hopefully my description will let you pick the one suited to you better. Both good choices. For me, I lean to the PM3.
Hey PDC3,
I just read that you had the opportunity to listen to the Sine DX and the Oppo pm.3.
I recently got the pm 3 to try out for some time. i must say I am a little disapointed. it sounds very flat and a bit boring to me. since i like rock and a warmersoundsignature, i guess its just a bad match-up. however, i ve been interested in the sine dx for a while now. as i live in the germany i couldn´t listen to them yet as there are not on sale yet can you say something about how the dx compares to the pm3 regarding to sound (i guess comfort seems to be a obvious one..lol)?
how is the soundstage on the dx? due to its open-back but still on-ear design, is it any good? comparable to over ear open backs with smaller kinda soundstage?
thank you!
