New Shunyata Sigma X series with QR technology

[audioquest4life]

Thanks very much. I really appreciate your input.

I've had Sigma V2 NRs on all my source gear (connected to an Everest with Omega XC to the wall). I've replaced them with Sigma-X NRs on all the source gear and I'm blown away by the increase in noise reduction, detail, clarity, soundstaging in all dimensions, and overall presence of the sound (and the Sigma V2s are no slouches in those regards) – it's pretty remarkable.

However, I'm also noticing that the overall sonic presentation of the Sigma-X NRs seems fairly aggressive with significant energy in the higher frequencies, which on many tracks is a bit fatiguing. I have about 60 hours on the cables thus far, hence my question about any changes you've heard when your Xs settled in completely. And also, how many hours would you guesstimate that it took for the settling in?

I wonder if the new Sigma-X QR's would make a positive difference compared to the Sigma X - NR's. Do you use a Shunyata conditioner with the Sigma X -NR's or are your amps plugged directly into the wall? I am thinking about the Sigma X - QR variants for my future upgrades.

Thanks for commenting!

All four of my Sigma X-NRs are plugged into my Everest, which is powered by an Omega-XC. Sigma X-QRs for my front-end gear is going to be too pricey for my budget (and certainly Omega X-QRs would be, too!).

Per Caelin and Grant at Shunyata, each of my Pass monoblocks is plugged straight into a dedicated 20-amp circuit with an Omega-XC.

Has anyone upgraded to Sigma/Alpha-x from non-Shunyata brands? Would love to get your take.
