I had the Linbrook Signature for 2 years, and now have the Decade D1's. Overall: a bit more full, much deeper, throws a more accurate soundstage, sounds richer, easier to drive for most amps. There is incredible clarity in complex orchestra passages. These are some of the best speakers I have ever heard at this price; since these were broken in, I haven't heard a $20k system at a dealer that I think even comes close to how my system sounds with these in it. If I had to rate the speakers; the old LSS was like a 7.5 out of 10, and the D1 is closer to a 9 out of 10 (I don't know if I have ever heard a "10" speaker, but maybe that is what >$25k buys you?)
Also, they are pretty electronics-friendly. The only amps they didn't sound so hot with were OTL amps. They have sounded pretty good with KT-88 based amps (cheaper ones are all I have tried, but have a set of M150's on order), and sound great with the SS gear I have tried out in the system.
