Am i missing something without a power conditioner?


I need your advice on power conditioners. I know there is alot talked about with power conditioners. But let me explain my situation and what i have. First and foremost i upgraded all my stock power cords. I am using and have a Krell FPB 600 amp with a Shunyata Research Sigma HC power cord. I am using and have an Audio Research Ref 6 preamp with a Shunyata King Cobra Helix CX power cord. And have a Rega ISIS cd player with a Shunyata Sigma digital power cord. I have 1 dedicated 20 amp line with a 4 plug 20 amp wall outlet that my amp and preamp plug into. My question is with these high quality power cords do i still need a power conditioner?

Especially for amps, it can be a good idea to check with the manufacturer. Some have definite views about using power conditioners with their products.  Otherwise, I've just gotten clear improvement installing an AQ Hurricane HC cord to my Aesthetix amp. But there are a lot of good wires out there.

O yes, the Hurricane cord for my amp goes straight into the wall.

aalenik ....That is exactly what i heard also from alot of people. That putting a conditioner on a power amp is like putting a condom on it? Now ive read alot of good reviews about the Shunyata Denali 2000t conditioner for HC amps. I too honestly dont know. And being that i want to find one used you can forget about demoing it.                                                                                                                                                                                                        billshenefelt... Yes thats exactly right !!!
@tattooedtrackman, I have a Shunyata Denali 2000t that I have tried on my Plinius SA Reference amp. Although it did not have a negative effect on the amp, it also did nothing positive that I could detect.
On the other hand, I did hear an improvement with my Transport and Dac plugged into the Denali 2000t and/or Preamp.
lak.... Il tell you the Gods honest truth. I was really listening to my system to hear if i really need a conditioner. The sound seems so clean and so pure that i could not imagine how cleaner my system could actually sound. I really think it would be a very big waste of money as of now. I really can not see my system sounding any better and more cleaner than now even with the best conditioner there is.
