I have been a user of Vermouth Audio Black Pearl speaker cable for number of years now. A few moons back, Vermouth Audio have released a new Reference series cables and I managed to get a sampler for their XLR interconnects and power cable.
Given Vermouth is close to my heart, I have chosen to write the review for Novo High end instead to get a more international coverage. You can read the review in the link below but you can listen to the samplers from the videos on this page.
