The new model has incorporated numerous technological advances, while retaining the best elements of the TL-7.5 platform. The proven advantages of the original system architecture include: a fully balanced differential design; a hybrid circuit that combines tubes in a gain stage to provide voltage linearity (less than 2 dB NFB) with a MOSFET buffer for greater current throughput; a high-resolution volume control; and a clean box/dirty box architecture with multiple precision controlled power supplies.
The VTL TL 6.5 Series II Signature uses a fully discrete balanced circuit, a FET buffer in combination with lamps (2 x 12AU7/ECC82), an ultra-precise volume control (95 steps, 70 dB) and a brand new power supply.
The VTL TL2.5 preamp is a relatively inexpensive tube preamp designed for maximum realistic unpainted music playback. It has all the necessary functions to coordinate and control other components of the audio system. The VTL TL 2.5 has 6 line inputs, allows additional installation of a phono corrector, and is equipped with two pairs of outputs, a tape loop and a processor loop.
