If you have a VAC Statement or ARC REF box plugged into something other than another one, maybe because you couldn't AFFORD it.
Is system synergy worth having matched components?
What have been differences you have noticed in listening to amps and preamps from different manufacturer's together compared to a combo from the same manufacturer? I love my current setup of an Odyssey Audio Khartago plus amplifier and Aric Audio Unlimited all tube preamp. It sounds great to me. But am I doing myself a disservice by not even hearing the Odyssey Candela or Tempest preamp with the Khartago?
