I have been using this GS-LCR for over three years now with very satisfactory results really.
It complements my full Monitor Audio set up consisting of Gold GS Floor-standers and front surround GSFX.
I use a set of small Bowers and Wilkins to the rear and three REL subwoofers; B2, B3 & 505 connected to the centre, driven with a Yamaha RX3800 WITH REALLY GREAT RESULTS.
Lately though with the launch of the Platinium 200 series and new centre PLC 150, from what I am reading, the technology in these is far superior to the Gold Signature Series.
