Incoming impression of the full line of the "new" Westone BAs.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Introduction
I was trying out the newer Westone BAs last week as a way to test how BAs sound and if they can provide the possibilities of being an upgrade to my GR07s MKII.
Test Equipment and Method
Source: iPod Classic
Test Tracks: Versailles-"Illusion" and Versailles-"Created Beauty" both in 320 kbps MP3
The IEM's were first given a solid 5-10 min of play to hear their overall presentation, then ABed against each other and my GR07. Somewhat level matched, volume was played up and down to compare with the previous IEM's volume level as I ABed the IEM. This was done to get rid of loudness bias as much as possible.
Impressions
In order of which I tried first, my impressions while I still remember and how it went down:
UM PRO 20: I hear no difference between this and the GR07s, well barely but not enough to warrant a $300 price tag. Just not impressive overall.
W20: Slightly V shaped sounding for my liking but treble was much more pleasing compared to the GR07s and the bass just as good. I can't really see it as an upgrade to the GR07s though but I really liked the seperation of the bass and the treble. As an upgrade, I wanted vocals to shine, these didn't cut it for me but still liked the presentation.
So since I wasn't all too impressed with the UM PRO 20 and the W20 fared better, I didn't really bother with the UM PRO 30 so I went straight to the W40 thinking it had to be the better IEM.
W40: Vocals are wide apart compared to the previous Westones and GR07s, pretty cool sounding presentation of the vocals. Treble sounded rounded (made guitars sound smoother, I am kind of in the fence whether I liked that or not) but more evenly impactful if that make sense. I liked the instrument separation, much better than previous Westones and GR07, and easier to focus on one of the instruments at a time. Not a basshead but I always test to see how the rhythm section of a band performs in a pair of headphones. Bass didn't really stand apart enough from the W20 so I was indifferent towards it.
Well, I was set on the W40 until the seller dropped the price to me -.-. $500 is too steep and doesn't really blow the GR07s at that price, I would've taken it for $400 at the most. Then I re-tried the W20 and contemplated with myself whether it is good enough as my first foray into BAs. I was hesitant to ask for the UM PRO 30 to try as I already had 3 IEMs in my testbench. I didn't want to come off an indecisive noob without a purchase after an hour of intense ABing. But alas, I did ask for the UM PRO 30 and I was glad I did.
UM PRO 30: Such clear vocals (much more intimate), my Kamijo just sounded amazing. Felt like a rediscovering of why loved his voice so much in the first place. The instrument separation was brilliantly presented (maybe its a BA thing, not sure but it was convincing enough to know this is a clear upgrade to my GR07), clearer separation than the W40s. Treble sounded just right to me, with guitars especially. Not too bright, not too smooth, just right. It didn't have the roundness sounding that the W40s had and was much more lively compared to the GR07s. Bass sounded much more neutral, I don't experience the thumpyness that I hear with the GR07s and the W40 compared to this one.
Results
UM PRO 30 checked everything in what I wanted as an upgrade to my GR07, mission accomplished. I was out of the store over $400 poorer but sank deeper into audio nirvana.

TL;DR
Summary
ABing took over an hour but well worth it in the end...not so good for my wallet though X.X
Results of ABing and eroded gold platings: UM PRO 30 > W40 > W20 > UM PRO 20
