I borrowed a Corona Elite power cable from Sablon last week, it had Furutech ncf plugs and a synergistic research 13 amp (uk) blue fuse fitted .
My cables have Oyaide iec and Furutech 13amp (uk) plugs with Kimber 8TC cable. They have done me well for a good few years. I have a dedicated power supply to an isolation transformer plus an old Furman balanced power conditioner.
Anyway, thought it would be worth trying something more up to date.
I tried the Corona in my Lampi GG, phono stage and pre-amp.
It made a difference to all the equipment I tried it with, and most noticeably with the pre. It was not night and day but the sound quality was decidedly improved somehow. It took awhile to work out what the cable was doing, imo it was lowering the noise floor slightly and increasing the dynamic range particularly in the lower registers. I listen to a lot of piano music - one of the things I noticed with the Corona, it enhanced the sense of keys being struck firmly, the percussive element. In particular, on KJ's Koln concert - besides the dynamic contrast mentioned, his foot stomping became more tangible and spatial clues became more evident.
I only had it for a limited time but felt it was contributing to an increased involvement with the music being played, across the board. Other posters have talked about it blowing their existing cables away, I did not feel this was the case for me, maybe because I have a reasonably sorted power supply chain enabling the system to work pretty well. That said I shall be purchasing one soon, would also like to try out more than one as I guess the effect would be cumulative.
Dave, I found the Sablon PC gets even better over time and leaving without disturbing.
