Having already bought a Lector Reference CD from Mark which is beyond words compared to any CD costing many times more decided to upgrade my B & W CM10 S2 . Spoke to Mark who recommended The Audio Physic Virgo 25 as they would work really well with my tube system & offer amazing natural sound. Having let them burn in for 3 weeks I was amazed at how natural & musical they sounded compared to the B & W's, however mentioned they still sounded a little bright with the Tellurium Q Ultra Black speaker cables. Mark suggested I try the HiDiamond 7 speaker cables & Diamond 2 XLR as they offered incredible natural detail along with warmth compared with the TQ's. After 3-4 days all I can say is breathtaking rich natural sound without any of the brittleness & harshness that both the TQ's & Kimble Monocle XL offered. Simply put having tried numerous so called amazing brands from Nordost, Kimber, Tellurium Q etc, the HiDiamond not only offer the best sound by miles but just as important I haven't had to sell off all my internal organs to afford them. Once listened to everything else pales in comparison. Outstanding products backed up with quality knowledge & expertise.
