@stephendunn... I'm a cable believer however I've noticed the least difference with power cables. I am using a PS Audio P5 regenerator so I think they might have less an impact in my system since the power is regenerated. I love the P5 and did notice a big difference once I put it in my system. Anyway, I'm wondering what cable you replaced and what happened when you put your original cable back in? Did you notice a drop off in performance?
abd1...The Shunyata Omega replaced an Audience AU24 power chord, a David and Goliath match up.  This all came about because my audiophile friend insisted my old Audience cable wasn't good enough  for the VR.  I insisted that there was technology in the VR that made the power cord less important.  But I will say when my friend replaced another Audience AU24 cable with another very high end Shunyata pc (I think it was a Sigma NR V2) on my Totaldac, we could clearly hear improvements by degree but not the quantum leap the Omega gave us on the VR.

I have been a cable believer up to a point, thinking they were the classic example of diminishing returns in hi end audio.  But sometimes $7.5 grand really buys you that much of "better", especially if you're replacing an older technology.  I would have to sell another chunk of my Blue Note collection to afford it, so the jury's still out.

How did my old cable sound when I put it back in?  I don't know, I told my buddy I needed another week with the Omega to make sure I wasn't hearing things. (<:  
"Did anyone try LTA Z10 with the Cubes? Anyone have compared the Z10 to a SIT-3?"

The Z10 works fine with my Nens. However, I do prefer the SIT-3 combo; it has more life and dynamics.
@stephendunn Thanks for the reply. I'm like you where I've felt cables make a difference but also agree with the diminishing returns. Interesting to hear your experience, but for my wallet's sake I wish it weren't true.
The Z10 works fine with my Nens. However, I do prefer the SIT-3 combo; it has more life and dynamics.

Thanks @rwpollock yes, the SIT-3 sounds wonderful. I was trying to see if I can simplify the setup with an integrated. What preamp do you use with the SIT-3 ?
