Mrvegas, I have the Linbrook Signature Systems (1 Piece). I think you have gotten excellent advise. Go for it!
Regarding amplification, these are VERY revealing speakers. They do not have any of the upper-midrange/high end emphasis problems associated with a lot of "audiophile" speakers, in fact they might even have a mild dip in the 2000 to 3000 hz range, but that doesn't mean that they won't fully reveal the nature of the electronics you are using. You will hear everything! Very clearly! That said, I have been using 40wt tube amps (but I don't rock out) as well as large stereo and mono tube amps, very successfully. If you don't listen excessively loud, or have a huge room to fill, you don't need lots of power so long as you got good 4ohm output, tube or SS.
Re the DK - I would be very careful before I took that route. Many of the reviews that I have read by folks who have actually owned one have complained of a less than stellar upper mid-range (reminds me of the typical complaints made about inexpensive SS stuff - glassy, grainy, rought, etc). I haven't owner one so I can't testify. I know they are really cheap now (used for down to $1300) but, personally, if I couldn't hear one in my system I would avoid the temptation. FWIW.
Hope you enjoy your Tylers.
