Hissing noise

66.140.128.137

I am going out of my mind. Please help, my audiophile new friends. I recently sold all my gears to update to new sytems. First system consists of BMW CDM 9nt, ACR LS12 pre-amp, Anthem MCA20 amp, Marantz CD player and all cables ( inter & speaker cables by Kimber). Second sytem consists of Sonua Faber G/P, Parasound Hca 2205 amp,Parasound HCA250 pre, Marantz CD player, all cables(inter& speaker cable by Kimber). Both systems are in the same den, one is on each side of the walls. Everything sounds good if not wonderful BUT there is always a warm hissing audible 2 feet away coming from the tweeter and the mid-woofer.Not humming, not poping, not buzzinf just a hissing sounds.I have done the elimination process thru 3 power amps, 2 pre-amp, 3 pairs of speakers BUT the hissing noise still exists. Sonus speakers have the most audible hiss, next is the BMW then the paradigm bookshelves. I went out and spent my last thousand dollars on inter-connect and speaker cables BUT I still cannot get rid of the HISS. I turned off all other equipments ( computers, clock radio...) in the room nearby, It does not help.I went to the dealer, amazingly their speakers were dead quiet. They recommend the Monster power cleaner But I aready have the Monster HS2500 hooked up to my gears. PLease, If anyone knows the answer, help me. I am going nut here.All my gears are new. Can both pre-amp be at fault? Can all three pair of speakers are defective? Can both power amp be defective? Three set of cables, Can they be all defective? One note is the HISS is independent to the pre-amp volume.The hiss sound remains the same no matter I turn tthe volume all the way up or all the way down. Please guys, tell me whatis wrong here?
