I have own swan 2.1 for years and recently got a great deal of 4.1 and C3 for a fella in audiogon. I generally do not like to post comment in a forum. However, after owning the equipment so long, I thought I owe to the forum to give my 2 cents for those who might considered buying swan.

Review is on Swan 4.1
The strongest point for swan diva is really the midrange presentation. It was very clean, distortion free of sound in which you can turn your volume very loud without hurting your ears. It also has very good midrange detail that many high end speaker have hard time to produce. More important the midrange is very open and very smooth. What does that mean to your ear. Well, if you like to hear vocal, you are in paradise. The sound of the vocalist is so lived. Swan Diva 4.1 's midrange remind me a lot of my favorite speaker ATC SCM20SL. This is a high praise for those who know ATC. Of course, ATC do just a percentage better in all area of the midrange compared to swan. But for day to day use with music, you will be very happy with swan. The artist I used include Diana Krall, Allison Krause, Eagles, Micheal B. and etc. No matter it is female or male vocalist, the midrange swan present is just clean, detail, open and smooth.
So now is my least favor character of swan, the tweeter. Although the tweeter never sound fatigue and at same time, ti sound smooth, it lack of the ultimate details you want. In another word, you will have more desire for more. However, don't interpret this as swan is warm an laid back speaker, it is not. It is neutral for what it can produce. Well, to draw a comparison, swan's compare to ATC or Dynaudio, it certainly missing some details. But when it is comparing to NHT, it is very equivalent.
Now, this is the best part I found with swan 4.1 of not the entire series. The bass is tight and deep. Given it can hit in the 40Hz region, it is sure that it hit very well. The bass is tuneful and chest pounding. It has authority to make you smile with R&B music and popular music. With Jazz music, you will hear many details. What surprise me most is this twin 5.25 driver can produce bass feel alot deeper compare to dual 10 in the VT 2.4 in music only. I still puzzle how such small tower can achieve that. I thought Monitor Audio Silver 5 is pretty good in bass for small speaker. The swan 4.1 outclass Silver 5 and honestly VT2.4 (which I hated to admit)
As you can see, I like swan alot. Swan Diva series really deserve with have a high quality amp and preamp to drive. I remember initially with 2.1, I use yamaha DSP A2(2095) to drive it, it sound harsh. Ever since I switch to separate with Sherbourn and Sunfire, it make it sound very very high end. Lately, I bought the Shengya hybird amp, now is hook with 4.1, it make the swan sound close to very expensive speaker. To a point, I no longer crave for my favorite speaker ATC. What a relief(money wise)? So, for those of you who might find swan not sound as good as it advertise, make sure to hook up a quality amp before making your final judgement. I think you will be reward with that.
So much for my long review. I really like to thanks the folks who bring swan to the market here (both av123 and theaudioinsider) I hope future version of swan can improve the tweeter while keeping the rest intact. So long and enjoy!
