Jon2020, in general, if you ever use a Shunyata wire on Puccini, I suggest you do not adopt a VX variant. . . VX contains pellets of a FeSi filtering compound. . . it is meant to shield the system from incoming and outgoing stray high frequencies. It is my understanding that the series was developed when a lot of CDPs were supersensitive to grunge, and in turn tended to inject grunge back into the AC. Outwardly, VX does have a smoothing effect, but at least on my TEAC Esoteric X-01 Limited, it tends to lacquer away extremely fine detail, and paradoxically introduces some minor hardness in the mid treble. Puccini being in the same league as X-01 is likely to experience the same issue. The Shunyata Alpha variants and the recent CX series have no FeSi filtering and do not cause any loss of fine detail. . . on the contrary, CX is uber-scrumptious! G.
