Have you actually owned , or used any models of either Pilium, or Soulution for a long periods in your own system to come to such "definitive" conclusions about these brands?! I m not a fanboy of the either brand's amplifiers, but whatever resultant sound I ve heard, especially with the Pilium was rather lush, grounded, tonally rich, and to my ears very far removed from anything that would have sounded sharp and hard. And that was in the systems using the Magico speakers, which nobody would describe as wooly sounding. And my hearing is intact, as I have it regularly tested with the audiologist, and can hear up to around 16-17 Khz. Also, in my opinion Pilium and Soulution have rather different sound signatures.
