Well, it said tell us about your system so...
I kind of have 2, more by circumstance than anythng else.
Naim 92/90 pre/power with a rega planet and Naim Intro 2 speakers started it off. Chord Co. Rumour speaker cables and cobra interconnects. Yamaha KX393 tape player, I'm a bit old school, or behind the times depending on how you see it.
Then wanted surround so got a Yamaha DSP E800 to maintain the HiFi when not watching movies and added a Miller and Kriesel S85C centre and Definitive BP1.2X bipolar surrounds with a M&K V 125 Sub (awesome) and an Arcam DV88+ DVD (an old one with the separate pro scan board), oh and a Sharp XVZ90E DLP projector.
Then had to re-arrange the room so got a Denon AVR 1907 for surround and M&K K7's for the front cinema and kept the Naims just for music and the latest addition is a Pioneer PDPLX5090 plasma with a PS3 for bluray.
The only thing now is that I've moved house and it's all in boxes. What a travesty !! I am just waiting for enough time to re-decorate so I can get it all out again.
