After having my cd player repaired and upgraded, and being so very impressed, I decided to ask John to get to work on my amplifiers as well. I continue to be impressed and my hi-fi improves every single week (I’ve had it for 3 months now) and I’m really looking forward to seeing where it eventually ends up. My only regret is that I don’t have anything left for John to work his magic on! An upgrade that is worth every last penny that you spend!!
