I have been testing one of Frank's power cables over the last few days with some interesting results. He kindly sent me a Stratos cable which, I believe sits below his top of the range Jupiter cable but above the Mercury. My system is currently wired up through standard kettle leads that Cyrus provide when you buy a component. The only specialist cable is an Istotek power cable on my Pre-X.
I am now very happy with my system and feel I want to get the very best from it in terms of bass, treble and overall soundstaging, but know that tweaks are going to be subtle improvements if anything.
First up, I hooked the Stratos onto my Cd player and sat back with a coffee. After about 5 minutes it was clear that the bass was tighter through the Dyn's and there was more air and life around the music with vocals rolling off slightly more. Yello's Stella album was on and my foot was tapping well. Pleased with the subtle improvements all round.
Next I moved the Stratos onto the Pre-X and this is where I feel the biggest improvement came. If anything with the cable on the Cd player there was a hint of clinicalness and dryness to the sound, but on the Pre Amp the sound was much more rounded with a much more natural texture. Timing is absolutely spot on using this cable, the bass is rock solid as before there was a sense that the Mono'd Smarts were doing a good job controlling the Dyn's but there was a touch of flabbiness to the bass. Not now.
I was considering buying a Nordost Shiva as the performance enhancement when I tried 4 of those on my set up was a step forward indeed. However, I seem to be getting the same results from the Stratos at a third of the cost so think I may stick with this one. Going to see if I can get hold of a Shiva at the weekend to do a back to back comparison.
So I guess all good so far! I can only recommend you try these and see what you think. It's working for sure on Mr R's rig! Believe the Jupiter is quite something...Technobear? Your thoughts?
