Vsonic GR07 MKII vs Vsonic GR07 Bass Edition
Tracks used:
1) Gotham's Reckoning - The Dark Knight Rises OST
The BE simply sounds EPIC on this track. The low end weight is reminiscent of the main villain in the movie. It's strong, yet fast and articulate. The great thing here is that the atmosphere of the song does not suffer at all compared to the MKII. The main difference here is in the starkness of the detail. They both have similar amounts of detail, but the BE's bass quantity tends to soften the immediacy of the presentation. This also lends to a smoother top end.
One important thing here is that the MKII has "enough" bass to carry the song. The BE just has that extra oomph to put it over the top for those who want more.
2) Oakland UFO - The Flashbulb
Again, the BE sounds more euphonic here due to the bigger bass and warmer presentation. Despite the MKII having slightly more clarity, I prefer the BE for the way it adds extra fullness to the snare and synth sounds.
3) Little Lion Man - Mumford and Sons
This particular track isn't the most well mastered track, so the extra bass of the BE sounds a bit out of place here. I also preferred the MKII's slight boost in clarity, as it was useful in making out some of the more hidden details.
Overall winner: Tie.
The Bass Edition is exactly what the name implies, a GR07 with a boosted low end. The side effect of this is a warmer, more euphonic presentation that may or may not be to your liking. In the course of my listening, I found the BE would work better for some tracks, while the MKII would work well for others. It's really up to you to determine the kind of presentation you want.
