Recent engineering breakthroughs have resulted in a major upgrade to one of VTL’s most important products – the TL-7.5 Reference Line Preamplifier. Four years after introducing the TL-7.5 to universal acclaim, VTL has revised it for an even higher level of performance. The new design, known as the TL-7.5 Series II, adapts current gain technology developed for the new TP-6.5 Signature Phono Stage.
