I owned Vandersteen 2C's (not 3's) and Linbrook Sigs and they are very different sounding speakers. In my opinion the Sigs have a very forward sound as opposed to the laid-back sound of the Vandersteen. The Sigs were also very directional with a very small sweet spot. If you moved your listening position at all (vertically or horizonatally), the sound changed significantly. the Sigs were also a very difficult load for an amp, and they were very sensitive to all upstream equipment. To me the Sigs had great resolution, transparency and detail, but it came at the expense of sounding forward with alot of emphasis on the midrange. The Sigs are beautiful speakers and Tyler Acoustics is a great company, so you can't go wrong, but only you will be able to decide if they are an upgrade.
