Just grabbed a refurbished PM3 for £200 (~$260) which is £150 lower than the RRP here in UK. I cant tell enough how happy I am for what a bargain it was so I want to share some of my personal, subjective impressions.
The PM3 exceeds my expectation for even the original price. Pairing them with the Apogee Groove with PC-Foobar2k-24/96 as source and it almost knocked out my HD650 in terms of mid and sub-bass details. The quantity is less but the quality is more hands down.
comfort as well cause the HD650's clamping force is just more than enough for my head.
The sound signature to me is more flat, neutral and analytical on the PM3 compared to the HD650 that to my ears, on the warm, musical side.
The sound is more laid back than the 650 which to me is a good thing as it increases the relaxing feeling and decreases the fatigue in long listening sessions. As a planar magnetic pair of cans, it is also much faster.
On the other hand, the parts which the PM3 falls short to the 650 is the emphasis in trebles and upper mids, they are crisp and clear but a bit dry, this some times result in less satisfying jazz/blue tracks with female vocal like Norah Jones or Ella Fitzgerald. And of course the soundstage which is obvious when comparing the an fully open back pair.
I even enjoy them very much straight out of my iphone 6s with the traditional 3.5mm output or the lightning port with the lightning to 3.5 adapter (with a tiny dac inside and costs £9, sounds a little nicer than the 3.5mm with internal dac).
Moreover, aesthetically, it looks so nice on and off my head, the cables are neat, sturdy and seems not to get tangled much, altogether make it an ultimate portable choice.
Last but not least, any suggestions on portable dac/amps with the PM3?
I just got the HA2SE, they sound nice but I am not quite happy with the £289 cost in terms of details and soundstage improvement and about to return them.
Thanks for reading and have a nice day everyone, Ling.
