My stepping stones have been Sennheiser PX100s, PX100 iis, V-Moda M100s (blew away the Senns), and tried my dads Senn 598s for a few hours, and now looking for a be all and end all to replace them.
LCDs won't replace them for portable use of course unless I opted for the X's or Xc's.
But the whole point of Planar is to offer a more natural open sound so having a closed set seems counterproductive.
I find my M-100s to sound wide and they are closed though... Detail isn't lacking either so I'm expecting probably more than I should be.
Bass is apparently phenominal.
Started using Tidal lossless too yesterday. I felt there was a difference to Spotifys 320kbps stream
In retrospect I would have gotten the X- one starts to really appreciate that aluminium housing after so many instances of wood cracking on the cups...
The X is more neutral as well, and if I had known back then that I prefer a brighter sound signature than the 3 I would have gone with the X. I only found out that I prefer such a sound after I got a HD800. You really need to try many other cans that are at the same price or lower, especially HD800. Coming from some mid-fi cans like HD650 I didn't have enough experience with other contenders and so when I heard the X&3 I was not so much blown away (but the difference was large enough to be perceivable).
Right now I like that the 3 complements my HD800's bright sound signature but I don't use the 3 a lot because of the lack of high-end frequencies. I now think I should have gotten them used somewhere, new is too much. Though I must say it does bass and mids well....but I have since moved onto SR009s.
