Having the V6 Classic in the I/V stage and the V6 Vivid in the LPF stage improves the already technically-excellent Playmate by adding texture and revealing more details in the recording. Even with the increased detail, there is no harshness to speak of. It is pleasant to listen to, it provides ample detail for those who demand it, and it has enough power to drive any headphones or power amp to satisfy any listener. Congratulations, Burson Audio, on this fine product.
