Vinyl Pre-Amplifier

  
Many designers opinionate that NFB loop controlled amplifiers are inferior because they degrade the sound, and yet I wonder what it is that these individuals think they actually listen to ? The fact is that most vinyl waveforms and CD pits, as pressed into their own disc collections, have already been mastered through a myriad of NFB loop controlled pre-amplifier and mixer stages - this long before anyone can start listening. Indeed, that Mullard developed TDA1034NB integrated circuit which initially cost me ½`£67 for ten, went on to be used by the hundred within what became a classic series of world famous Neve mixing consoles.
