The Linbrooks are more efficient at around 92 db (4 ohm). I currently have 2 pair of the Taylo reference monitors in my home using Cary 40w tubes with one set.
Works great but I don't listen to AC/DC anymore(90% Jazz) so I can't tell you about SPL's in this setup. I would say that the Linbrooks would be the better choice of the two and the Taylo's would probably not be satisfactory in the setup you are attempting. They will sound fine but they won't perform the way they were meant to, but I am totally sold on Ty and his products.
In my second system I use Cary CD/Cary SLI 80 Int. Amp, my other system is Cary CD/Levinson. One is sweet, the other can be rather garish in an incredible way. Tyler Acoustics is the best value out there. Period. Are you currently "tubed" or just thinking about sticking your toe in the water. If you are going all the way toward that Set tube magic thing, consider picking up some Cary 805c's that have been tubed with WE 300b's....awesome, but good used examples will still run $4500/pair.
Best wishes and good luck on your setup!
