at moment using a onkyo nr801.. its purpose is my game room but its filling the void till i get me 990 .. i've had Harman kardon sig 2.1 2.0 and marantz etc .. as prepro 's .. now my ATI 1506 is craving a good prepro .. the onkyo 801 is a reciever but the pre outs are decent and i use the direct out to my audio control eq for tampering with the signal to my tannoy Dual concentrics .. i have the 12dmtII as mains at moment and saturn 8 floorstanders for rears and a d6c center .. one custom sub with a 250 rms 456 peak .. amp pushing a boston acoustic 13" generator .. very tight no mud .. then a harman 12 that i use out of phase for a eefect that really gives a fullness. ... the dmt 12s do fine without a sub on stereo.. i probably will stay 5.1 .. enough for me .. but who knows .. i have my 1506 i have fronts and backs one channel each and the last two bridged to the center .. the 1506 is cool because its versitile .. 3 5 6 channels .. anyhow the onkyo is for the game room .. xbox etc .. to replace my hk310 reciever .. no video up..
