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?

Yes, if your objectives are enhanced system performance, better sound quality and greater enjoyment, etc. 

My question is with these high quality power cords do i still need a power conditioner?

Unfortunately, you ask an open-ended question that is system dependent and the only way to know if you will hear improvement is to try it and judge for yourself.
With that said, depending on which power conditioner you might try, results will vary. I believe that most likely with a power conditioner you will be able to hear more micro details however the percentage of improvement vs the cash outlay for the power conditioner might be marginal. I have four different types of power conditioners that I retate between two different systems and I hear improvement with all of them.
Like others said, you just have to try. I initially started by buying a used Audience AR1p (i think) for a couple of hundred. I plugged it into the wall and plugged my Wiremold power strip into it and I was very pleased with the result. So much so, I ended up with an AR6T that I’ve had since about 2009 with no regrets. I don’t follow the classifieds much, but I have seen AR6s (non-teflon) up at fabulous prices and it’s a first-class item, even without the T-caps. Maybe try one and check it out.  In fact, there is a 6T up for 2k, which is really a good price.  I know it's a lot of money, but cheap power conditioners can really ruin a system.  Good luck.
Dear Tatooed great name by the way.

Power conditioners are one of the most under apperciated and best things you can do for a system.

We have been doing this for over 30 years and have seen the countless times that adding a good power conditioner has made a stunning improvement in realism to a system.

We have also tried many of the major brands searching for the most effective units that would fit most of our clients systems.

We have tested over the years, Richard Gray, Exact power, Silver Circle, Audience, Shunyata, Isotek Gen 2, Isotek Gen 3, Audio Magic, PS Audio, Audioquest, Running Springs and I am sure a few others we have forgotten.

We are also running dedicated 20 amp lines with Furutech outlets as well.

Long story short the right power conditioner opens up a system's soundstage width and depth, lowers apparent noise blacker blacks, tightens up bass and aids in hearing and apperciating micro dynamics.

So in our tests even with really expensive power cords the right power conditioner makes a huge improvement.
