Yeah their new version came out this year (same price). Here is what they said about v2 :
《The new Opera has finer strands, thicker palladium plating, improved enamel coating, a new multi-layer Japanese fine cotton central cores, and a new custom TPU insulation that looks incredible, is super resistant, and would never lose its clarity.
The updated version has an improved, up-to-date design. As technology and production technics constantly evolve, we improve all our wires from batch to batch to stay on top with state-of-the-art wires. Testing the pre-production samples, there was a slight overall improvement all throughout, but the improvements are mainly in the wire design and materials, and it still has the same tonal characteristics as the current Opera.》
