Am i missing something without a power conditioner?

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

Power cords do not do any power conditioning.

The best power conditioners were made by a company called Elgar. You can find them on ebay; the 3000 and 6000 series are likely the most practical for audiophiles. The 3000 series can run 28 amps continuous and so can handle some pretty large systems. Because of their age, they will likely need some service.

These conditioners are so much better than anything offered to high end audio that its really a bit of an embarrassment. At full power they can deliver a sine wave with only 0.25%THD and they can regulate line voltage without limiting current within their ratings.

Running Springs can not be beat

@audiotroy how would you compare the isotek to a transparent conditioner & power cable. Esp what you feel it does to the sound?
Thanks 

Ralph, very few real audiophiles want an industrial, discontinued power regenerator, especially one that would or might need service from a company that really doesn't care about the consumer market way too impractical.

Also we have tested regenerators from Exact Power and PS Audio and none of them made systems sound as good as the best passives.

As per Transparent, never cared for their power products cable companies generally don't make the best power conditioners. 

Companies like Isotek do not sell anything other than AC products generally make the best power products. 

As per CPT we haven't tested them yet, there are people who seem to think that they are good.

There are a lot of CPT users on there forums for sure, it is how I heard of them and then bought one based on research and recommendations.
I am sure they are not the last word by far but for $1500 for a unit that could handle everything I run it was worth a test.
Biggest holdup is that CPT are pretty backed up with orders so may not be a quick purchase and delivery.
