@ricred1 > I'm debating between getting the Denali power conditioner or new power cords. I even have a debate about which power cord to get. Is there a significant difference between Sigma and Alpha power cords? Does the Alpha offer more value for the money?
I’d say look at some other PLCs that are contending as exceptionally well received and reviewed like possibly the CORT 1200 & 1800 models.

$2,000 with power cord
Power line conditioners are at times, great spots to affix a PC with noise reduction features. True that IF the noise reduction does not come at the expense of detail reduction or glazing over and leading edge performance dampning, which the VX versions were guilty of regularly. The helix versions seemed to better address actual ‘noise reduction’ without so much of the ‘VX’ ill effects.
RE Alpha value
It would sure seem from what Richard of Shunyata Res said to me, getting two Alphas would be the wisdom if only one Sigma could be swung financially, given the Sigs are twice the costs of a single Alpha.
With only four main entries on the latest SR PC lineup, the Alpha has to be some sort of mix between the performance of the former Taipan & Python cords, and the Sig more like the older Anaconda and or King cobra versions.
It was said the Sigma had a new tech in its build not previously instituted into any other model, ie., HARP.
It would sure be interesting to see the diffs from an Alpha and a Sigma on a source or amp. Just as exciting would be finding out if any for sure diffs were indeed to be realized between the NR versions and the non NR versions somewhere in the system.
