Deep Purple has been using HK Audio T-Series and M-Series speakers as onstage monitors. According to monitor engineer Rob Hodgkinson, “The new VT 115 X that we are using as stage monitors for Ian Gillan, Roger Glover and Steve Morse is one of the best 15-inch/2-inch monitors in existence. This box is just incredibly loud and clear.”…Veteran Clair Bros. monitor engineer Steve McCale picked the ATI Paragon II for shows with both The Eagles and Stevie Nicks, citing the Paragon's rock-solid stereo imaging. “Left-to-right separation is vitally important, and the ATI Paragon II has the best imaging and the widest dynamic range of any console I've ever used. It's my first choice,” noted McCale.
