"Now then, the reality of this scarcely an Hi-Fi sound  in comparison to the vinyl records!" that is hardly an Hi-Fi sound!"

Many of the harmonics that bring existence to the music extend beyond 20kHz (Kilohertz). Indeed good quality vinyl records can be extended well above the 20kHz Kilohertz). Sometimes the vinyl records can be extended to twice that amount above 20 20kHz. and still produce a useful output that is extremely trustworthy and dependable. It just goes to show that a good phonograph preamplifier with the right kind of gramophone turntable can bring far more musical gratification!
