The Denali has such a high level of noise reduction built-in that the NR in the power cables provides little to no additional benefit. We usually recommend the Delta EF, Alpha EF or Sigma EF for use as an input cable to the Denali or Triton power conditioners.

Hi Caelin, thank you so much!

Terrycwk... Welcome to AA! :wave:

Thank you Masterlu! =]

With the Typhon QR in front of Triton v3, would it still be Sigma EF wall to TQR and then the included TQR power cord between TRQ and Tv3?

If you bought the TQR (Typhon) after the Tv3 (Triton), connect the TQR to the wall with the power cord that you used to connect the Tv3 to the wall. It doesn’t matter if the cable was an NR or EF type. The TQR and the Tv3, both require a C19 type power connector at the input. So the cable used for the Tv3 is compatible with what is required for the TQR.

If you purchase the Tv3 and TQR together as the reference stack, I would recommend a Sigma EF to connect the TQR to the wall. Then use the supplied Sigma Typhon umbilical to connect the Tv3 to the TQR.

Hi Caelin,

Actually i’m using an Alpha HC for the Denali 6000T now, will improvement be significant if upgrading to a Sigma EF?

Thanks!

Hi Caelin,

I'm currently using an Alpha NR between my 6000T & the wall. (As my dealer didn't inform me that the Alpha EF would be just as good...)

How much of an improvement would a Sigma EF make? (I have my mono blocks plugged into the HC outlets, & my preamp, phono stage, SACD player, & active bass crossover plugged into the "source" outlets.)

Thanks.

The Alpha HC is one of the best high current cables we have produced.

However, the Sigma EF is formidable.

Just to be clear, the EF is not superior to the NR version. They are the same cable in construction and connectors except the NR version have built-in noise reduction. AAMOF, the NR is usually superior in performance to the EF when used on individual components. It is just that in this very specific application - the wall to Denali cable - that the NR has little to no advantages over the EF version. It is for this reason we recommend the EF version since it costs less.

And to be fair to the dealer, the EF version was released sometime after the NR version. So depending upon when you purchased the cable the dealer may not have been aware of it for this application.
