I have perform audition on both speakers from Edifier and Swan:
1) Swan M200MKii
2) Swan D1080IV
3) Swan X3
4) Swan M50W
5) Edifier R2700
6) Edifier 1600Tiii
What I really like about Edifier is the cover, which covers not just the speakers but overall front area instead of just the drivers, and find them quite solid, slides in/out easily, wouldn't break easily. Just that it has gaps at the sides (top, left, right, bottom), therefore, dust still can go in from the sides. Swan only covered parts of it (e.g. Swan M200MKii) which doesn't exhibit classy appearance.
When comparing my current multi-media speaker system (active speaker) vs Edifier 1600Tiii, the Edifier produces a lot of bzzz sound when hitting the peak, even with low-medium-high volume especially with vocals. (Treble and bass set as 0).
As for Edifier R2700, it did not display any bzzzz issues, it sound so smooth as if it was playing from my computer, an amazing experience. It sounds like a wholesome sound package with the tweeter, woofer and midrange speaker when playing movie sounds and soundtracks that has mixture of instruments (drums, violins, guitar). The woofer gave some kind of lion roaring vibration, great for movies. This is mostly lacking from speakers that only has tweeter and a midrange speaker.
For me, the Swan M200MKii sounds a little more crystal-clear compared to R2700 but does not feel wholesome (soft bass = felt non existent similar to my current speakers). It's suitable for users who are interested in instrumentals, vocals and sounds that has less bass in it. In addition, the Swan M200MKii sound quality is similar to playing on my computer, I couldn't really tell if it was a blind-test.
The D1080IV was great as an overall package but needs to position correctly at ear level, if its place above/below the ears, it felt empty in treble & bass. The R2700 when played at different position (standing/sitting), it does not affect much compared to the D1080-IV. Also, the D1080-IV, it felt half-full in sound, even though both are played at a comfortable nearfield distance (instead of blaring out loud). In terms of pricing, I would expect the D1080-IV would sound better than R2700, but it turns out to be the opposite.
Regarding the M50W, it has superb bass but weak treble. After I increase the treble knob, I could felt the clarity increase a tiny bit.
Swan X3, price the highest among these speakers, the woofers felt not strong, but the treble is ok. One thing I find it inconvenient is it does not have knobs to control the treble, and bass. Plus it has volume knobs but on both speakers. So it would be a little hassle trying to balance both speakers. However, this speakers does not provide a full-rich feeling from D1080-IV, probably due to the smaller size speakers.
So top 3 speakers would be: R2700, M200MKii and D1080-IV.
The R2700 feel more balance in all aspects.
The M200MKii hits the spot with crystal-clear sound but lacks the bass, and the design of the speaker shield doesn't look that appealing.
The D1080-IV is similar to R2700, just sounds less full than it (roughly 65-70%)
