Swans: For those unfamiliar with the Swans brand, they are a Chinese OEM speaker driver manufacturer for some time now and, in these days, cater mainly to the DIY community. They've not too recently decided to take the plunge into designing cabs and speakers for multimedia use. The D1010 we have here today is but one example of the plethora of offerings the make has available.
Build wise, these speakers are the lightest of the lot; (probably) solely because these are not bi-amped like the other two speakers. The wood-veneered MDF panels also appear to be a bit thinner than the other two and is a bit prone to fingerprint smudging. As a powered option, you'll have to make do with its proprietary 4-connector pin and sleeve speaker interconnect to daisy the main (right) speaker to the secondary (left) (unlike with Audioengine's or Aktimate's offering, which uses binding posts). Input is via a pair of RCA sockets on the rear panel of the master speaker. A volume control is also found on the left (right, when the drivers are facing you) side of the master speaker. Potential areas of user upgradability include: IEC (Figure 8) power connectors, and input interconnect cables.
Sound wise, the Swans captures quite a lot of detail from the DAC and reflects its aural signature pretty well. However, I do regretfully report that this is a pair of speakers that are not truthfully neutral. There is quite a bit of lower-mid and mid-treble colouration (a bit of a boxy sound) arising from a slight mid and upper-bass hump. And speaking of bass, (as expected) we don't get much sub-bass out of the tiny 3.5" polypropylene drivers but mid-bass isn't the monotone nonsense you'd get with lesser speakers. The mid-range, however, loses out on dynamics and transients and isn't really capable of delivering the pacey, lively sound from the GT40. Whatever that's left, however, is capable of delivering volumes of information on instrument and vocal textures, soundstage (almost being Grado-like with soundstage here), warmth as well as generally usable vocal/instrumentation separation without squeezing everything into an incoherent lump.
Overall, a decent entry level speaker. There are plenty of attributes that one would desire more from these, which it balances out by giving some levels of fidelity that entry users would love. So as a first step of departure from your generic Logitechs and Altec Lansings, this is a good start.
