Shunyata Denali 6000S + two Denali 2000T's + Sigma PC's

Does 6000 S or T come with power cord or do you have to get that separately?

It does not ship with one unless you request one specifically. They'll include a stock 20 amp iec cable for a nominal fee.

if you want to stay all Shunyata, buy a Sigma power cord. Remember though any 15 amp power cord should work fine with a 15 amp to 20 amp iec adapter. I prefer to use a Nordost Valhalla 1 with Denali.

Hope this helps.
 
Shunyata does not recommend the 20 amp IEC to 15 amp IEC adapter as a long term solution.

If you don't want to spend another $2500+ on a power cord for the Denali take a look at this one and see if it fits your needs.

With "audiophile" approved Furtech connectors for less than a fourth of the price after you take the discount and figure in the exchange rate. Or look for an equivalent Neotech PC. Another more than viable option is to contact Pete at Triode Wire Lab. His pricing will be in between the two but a highly respected product without the associated costs of the "big boys."

Of course not! You'd take a perfectly good cable and end up with a 15 amp termination that would not work! Not what I said...

The Sigma line is great and outperforms the Alpha. It's a great choice. The Alpha is a good choice if budget constraints do not allow for a new power cord that costs half as much as the conditioner itself.

BMW recommends only Castrol oil for my car's engine but I have been using Mobile1 for the last 50K Miles or 4-5 years. Drives great! [emoji6]

You said, "Remember though any 15 amp power cord should work fine with a 15 amp to 20 amp iec adapter."

I had a long conversation with Shunyata about this since I already have huge Rubbermaid containers full of 15amp IEC power cords. They strongly recommend against it as a long term solution noting that the adapter does negatively affect the sound. Fine in the short term, but not a viable long term solution for those looking to optimize the power foundation in their system.

P.S. I prefer Mobile 1 as well.

Lol... yes I did indeed but you were speaking of a different adapter, one that converts a 20 amp to 15 amp termination which we both agree would not be applicable here.

Thanks for the insight. By the way there are different quality adapters. Some are cheap in price and quality and others are very premium. The one I am using is a $200 adapter, pure silver termination cryogenically treated I believe. It weights a ton and is a thing of beauty. Made by VooDoo cables for anyone interested.

I have tried all of the following... 1) Shunyata Sigma, 2) Shunyata Alpha, 3) Ansuz Diamond and 4) Nordost Valhalla. I'm sticking with the choice that sounds best to my ears and expect we each will do the same.

Thanks for the info Mike. Best wishes for a great Sunday!

I have used these also, but when you compare using the adapter to not using an adapter, its amazing how much difference it actually makes.

Well Jock I guess you and Mike have much better hearing than I do. Fair enough. If I could actually hear a difference I'd just send my power cord to Nordost and have it reterminated. Hell I may do that anyway...

ALL Shunyata Research power distributors and power conditioners are rated at a full 20-Amp current capability and should NOT be used with a power cord rated less than that. The conductors in the power cord should be at least 12 gauge or better. Remember that wire gauge is rated inversely. As the wire gauge number gets smaller the actual size of the wire is larger. So, a 10 gauge wire is larger than a 12 gauge wire. For our European friends wires are rated in a more straight forward manner using the diameter of the wire in milli-meters or mm squared.

Also the DENALI Series uses an IEC C19 type inlet that is rated at 20-Amps. You cannot connect a standard C13-C15 type power cord into it. It is physically different. We use this type of connector because of the higher current rating and the fact that the contacts have a lower contact impedance and therefore better performance. The connector also has a much better grip on the power cords than the conventionally used type inlet.

RE: Power Cords
Although some people are using our reference power cable (Sigma) it works just fine with less expensive cables in our line up. The VENOM-HC is a great power cord with 20-Amp capability, 10 gauge conductors and superior molded connectors and plugs. It retails for less than US$300. If you want and can afford it - the best price to performance choice would be the ALPHA-HC at $1250.

Thanks Caelin. In your opinion, would it not be advisable to use a 20 amp IEC to 15 amp IEC adapter even in the short term? Thanks. Just trying to clarify as Grant had told me "only in the short term" - as in, "a few days while you wait for your proper 20amp IEC cables to arrive."

Relevant question for those who may elect to order or purchase another brand's 20 amp power cord. Barring some unforeseen production issue or stock issue, one can generally receive the Shunyata 20 amp power cord at the same time they receive the Denali unit so if going all Shunyata there's probably little need for the adapter. Another option is to request the stock 20 amp power cord with the Denali.

Every inline contact junction affects DTCD (dynamic transient current delivery) which is a major factor in power cord and power conditioner performance. We go to incredible (obsessive compulsive) lengths to maximize DTCD performance. We manufacturer our own wire and connectors. The outlets have contacts that are made from solid copper - not brass or bronze. Use use cryogenically treated IEC inlets. We even make our own custom wiring terminals inside the DENALI. Our Alpha and Sigma power cords are made with our own connectors that are constructed of solid copper base metals. So any adapter that you may use inline will be detrimental to the performance.

However, there are practical concerns when doing a trial of one of the power conditioners. Some people have their own expensive power cord and want to use it. Fine, we understand - just understand that if you use an adapter, you are not getting the full potential of the power conditioner. You can use an adapter for a trial but we do not recommend it for long term use of the power conditioner.

There are other more practical concerns about adapters. We make adapters to convert C15 to C19 and C19 to C15 and they are very high quality. However, just by the nature of IEC inlets and connectors - they are just not that great for contact integrity. It is far too easy for the connector to become loose or perhaps it was not fully inserted. If a contact is not fully engaged, the components will work OK but there will be a build up of heat at the contact junctions. This thermal noise can affect the sonic performance and in some cases can become a hazard.

Entertainment systems have high powered amplifiers and multiple components which means that a typical system can pull as much current as a space heater. We use FLIR and thermal probes in the development of our products and you would be surprised how hot a properly functioning connector can become when under a typical load.

If you want to use an adapter to a single component - I don't have a huge problem with it even though it will degrade potential performance compared to a direct connection with a high performance power cord. However, I DO NOT recommend using any adapter between the power cord and a high capacity power distributor or conditioner.

Thank you Caelin. I will remove the power cord and use the Sigma.
