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?

Tattloe iam planning to connect my Dac, transport, CD player , and preamp. Lak Iam looking into the niagara 5000 n thunder pc....or maybe start with niagara 1000...
I tried the AQ N 1000 recently, and could not discern any difference with or without it in the system.  Hope YMV.

Just to add to the opinion mix. Most of my clients choose not to use line conditioning or heavy power cords.

I forgot to mention that power conditioners often have multiple circuits fit with different filters [and manufacturer twaddle to accompany].

The 5300 has two 'Regular' and 1 'High' current circuits. One  Regular switched and the other not. The Regulars are recommended for TVs, preamps, CD, etc. and the High ostensibly for Amps and Subs.

FWIW, my PrimaLuna 5 sounds best when connected to the Regular direct rather than High current outlet. OTOH, the NuPrime ST-10 loves the High current outlet. The PL5 has a much simpler higher voltage, lower current PS than the ST-10.

Bottom line is not only will power conditioners themselves have varying effects, various circuits therein, if fit, may react in audible ways with the load device power supply.

By your thought process there really is no point ANYBODY making any recommendations then?
Makes me wonder why we are even commenting on this thread.

Surely part of the process is for readers to base an opinion of what they MIGHT expect ?
If say 95% of respondents state they had similar results with product X then it would be a safe bet to assume you would as well. Of course you could be in the unlucky 5% but sometimes you take that chance.
I base my purchases of peer reviews, recommendations, popularity and a good dose of common sense.
