TL-6.5 II Signature

About the TL-6.5 II Signature

The TL-6.5 Series II Signature Line Preamplifier incorporates advanced technology from VTL's flagship TL-7.5 Series III, including a revised power supply based on current-sourced shunt regulator technology for precise power regulation and noise rejection. It features a redesigned high current gain stage using normally-on FET technology that operates similarly to vacuum tubes, resulting in a more tube-like sound with zero global negative feedback. The preamplifier includes re-voiced audiophile grade capacitors and additional bypassing, enhancing sonic character with more defined imaging, inner detail, and improved mid-bass and midrange. It is a fully balanced differential design with a hybrid circuit combining tubes in the gain stage and a FET buffer for current capacity. The user interface offers intuitive functionality with full remote control and RS-232 compatibility. The unit uses 2 x 12AU7 tubes and supports multiple balanced and single-ended inputs and outputs. It features a 95-step discrete resistor relay attenuator for volume control and gain switching with 6dB reduction. The power supply includes ramped filament soft-start for tube longevity and large energy storage for noise elimination. Overall, it is designed for musical purity, integrity, and compatibility with VTL's Signature product line.
