i had a bunch of audiophile friends over and one of them is the distributor of the cables i'm currently suing as the long interconnects…he told me that those particular ones that i have between the pre and the mono blocks are not shilled and most probably are picking up some hum from the nearby power cords…well, i hope that's the cause…i have contacted the manufacturer and he's going to make me a 5.5m pair on shielded interconnects that hopefully will take away the last bit of hum present…
now, getting back to the sound…all 5 of the guys loved the sound…even with that little bit of hum, they agreed that the speakers sound great…:)
now, the other speakers we tried weren't too shabby…if anyone is interested i'll give more details about that via private messaging…:)
thank you for all of your suggestions!
