Just bought my PL20 from TS.
The first impression is , theres barely any bass. Those beat seems kinda fake.
so i guess i have to burn in first. its 15hours, theres hardly any difference at all.
Could it be manufacturer defect?

Here is a that might helps: http://www.head-fi.org/forums/f4/describin...lossary-220770/

Also, PL-50's review has been posted.

For those proud owner of PL50 who not satisfy with it bass performance... Find a day and drop by The Curve Sony Wings... plug ur PL50 into the SonyX-series and walla!! magic happened. U will be surprised of how well ur PL50 can perform...

Haha i owned a Sony X-series now ....Sony's EQ are good ...anyway i just bought a PL21 .... its really good though...
I'll try saving up more to get the PL50.. 

Too bad the only player out there with a 100+ Gb capacity is the iPod, so that's my only logical choice. I cant stand not having my entire library with me, and I hate having to swap tracks in my player every few days.

Mmhmm i think it's because EP-630 has it's own definitive "sound signature"
So whatever comes from the source, will sound like ep-630. i know it doesnt really make sense but yeah.
Whereas for soundmagic it plays exactly what the source is sounding like. And the "sound signature" follows the source more than the IEM itself. Poor source will reveal it's flaws clearer IMO.
Yeah man, no EQ better.
In fact having direct pass-through is better, more DSP in the chain causes more loss in sound quality...

O.o ClieOS i thought he reviewed it once?
