Power Cords - Equipment Priority?


I was reading a current thread regarding power cords.  Very interesting! 

I am using the stock power cords that came with my equipment. 

In total, I have 7 pieces of equipment with stock cables:
* power conditioner (thought this product came with an IsoTek EVO3 Premier C19 power cable)
* integrated amp" dac* turntable* two subs* bluetooth receiver feeding into dac (of course, it uses a stepdown powercord)

Assuming the IsoTek power cord that came with the power conditioner, how important or what would the added value to upgrading the other equipment's power cables?

In other words, is it beneficial to have upgraded power cords on all equipment or just the power conditioner?
Thanks

@malatu - Cables are a very complex area to delve into and an area I have been investigating for many years.

I have found that the "amount" of improvement from power cords is dependent on the components. i.e. The better the power supply in the component the degree of improvement is less noticeable.
e.g. my integrated amp has a very good power supply, so using a third part power cord on it would not yield the same level of improvement as using that same power cord on my streamer that has a less capable power supply.

Having said that - for the best "bang for the buck you can get "similar levels" of improvement by putting an extremely good ($$$) power cord on the amp and a lessor ($$) power cable on the streamer.

Putting an extremely good power cable on ALL components is a "safe" approach, but can be a waste of your budget - i.e. unless you have lots of spare cash lying around burning a hole in your pocket :-)

As to which of the three cable types provide the best bang for the buck I have found the following...
- interconnects allow your components to get the signal to the amp - so good IC’s are imperative and I have found to be one of the most noticeable upgrades.
- speaker cables get the signal to the speaker - I found using the right cables provided the biggest improvement in sound
- power cables are perhaps the most daunting of the three, because gear tends to respond very differently with each cable/brand/component

I have spent more time on cables than I care to admit, but for me, now they are the most important "component" in my system - even my very affordable streamer performs way above it’s "snack bracket" when connected with good cables.

Good power cables on subs also provide considerable benefits because it allows the amp to exert more control over the speaker.

The only commercially available cables I recommend these days are...
- NORDOST
- KLE Innovations

They provide similar "levels" of very noticeable performance improvement. But unfortunately they are at the upper end of the cable price range. Having said that, once purchased, you may never need to replace them.

If you are into "serious DIY", by that I mean making the actual wire, not just buying bulk cable, I can recommend a Helix Design that I use throughout my system. to great effect.

If you just want to build you own cables using good a good bulk cable and connectors - look at the DH Labs bulk wire and use Sonar Quest silver plated connectors (Ebay). They will outperform some of the name brand cables for a least amount of $$$.

The problem with DIY power cables is - you really should be aware of the electrical codes in your area and adhere to them, otherwise insurance coverage could become an issue.

DO NOT ever use solid core wire for component power cables since it is not recommended by many electrical codes due to fatigue failures (i.e. breaking).

One last point - replace the wall outlets with Pass and Seymour MRI grade outlets - they clamp like a vice and do not contain magnetic materials

Hope that helps and apologies for the long post - Steve




DO NOT ever use solid core wire for component power cables since it is not recommended by many electrical codes due to fatigue failures (i.e. breaking).
Probably the majority of audio grade aftermarket power cords made today use solid core wire for the hot and neutral conductors in their construction.

Individual insulated solid core wires are paralleled together to make a larger gauge conductor.

@jea48 - I sorta generalised - I should have said DO NOT use ROMEX solid core wire. 

A case could be made for higher quality solid core wire being softer - as in the case of Gutwire cables. 

But I prefer not to use solid conductors at all because apart from breaking, the clamp in the connector can work loose resulting in arching.

And that's not the only problem - some cables  use wire that has insulation not rated for mains use,  e.g. they actually use speaker or interconnect wire for hot and neutral - I only use wire rated to 600v - a common mains rating.

Beware of cables that have forged UL stickers - not a good sign and very hard to spot

One cable I purchased around 10 years ago had LIVE/NEUTRAL wires connected in reverse polarity - which would make the neutral side of your components power supply circuitry - LIVE!

Lots to be aware of - another reason for going with a trusted brand or build it yourself

I have to agree with boxer12 and jbrrp.  Over the past 20 years, power cords have made the largest impact in my system when it came to cable upgrades (i.e., ahead of IC and spkr wire).  Depending on your box count, IME the first place the cord should go is the amplfier and a close second on your digital source (with a PC designed specifically for digital gear). 

On another point, off topic a bit, is the use of isolation transformers.  I've owned several well known PLCs in the past, but the most effective by far is an isolation transformer.  While there are several audiophile approved companies making them and audiophile prices upwards of $2K, I found a hospital grade Powervar iso xfmr on Ebay for a tad over $200.  I put in some better outlets/wire and WOW!  Line noise gone, lower noise floor, more texture, etc.and no downside.  Granted Imy amp is only 100w/ch, but larger iso xfmr are available.
