The story as well as the technical challenges around "WBT Plasma-Protect" are unquestionably impressive, indeed, fascinating. However, what counts in the end is the musical result. Of course we think the environmental aspects to be great, but we also wanted to know whether the sputtering process would manage to further improve WBT's "Nextgen" line, which was already ranking at the top end of the quality range.
From HMS we ordered two identical sets of the top "Suprema" NF cables (assembled stereo-meter around 2100 Euro – WBT hat not increased the prices), which were identical including the Nextgen plugs. The only difference was that on one set the contact pieces had gone through the previous galvanic process, while on the other the contacts came from the new PVD process. To avoid further cables, we connected T+A's MP3100HV media player with their large integrated amplifier PA3100HV so that only an additional loudspeaker cable was needed.
Anyone who thought that the differences could only be "superficial" was quickly taught better. A challenge for every chain is the high bit file (24 bit/192 kHz) of an orchestra, shimmering in colors, which plays the second movement of Debussy's "La Mer". With the PVD connectors, the concert hall seemed to be acoustically more deeply illuminated, the music groups moved further away from each other so that the three-dimensionality became clearer. There was more light, air and complexity in the performance.
This was also the case in the tingling beginning of "I Remember Clifford" by the Beets Brothers and Hans Dulfer, which also played as a 24/182 file. The applause tickled even more beautifully, the saxophone breathed softer. Conclusion: 2:0 for PVD!
