The TL-6.5 Series II incorporates most of the advanced technology found in VTL’s flagship preamplifier, the TL-7.5 Series III, for a dramatically higher level of performance compared to the original design. The new version features an extensively revised power supply based on current-sourced shunt regulator technology that minimizes impact on the audio signal. Far more precise power regulation yields dramatically improved rejection of noise and AC fluctuation.
The completely redesigned high current gain stage utilizes newly available FET technology developed for green technologies such as solar panels and electric cars that require a normally-on state. Unlike MOSFETs that need to be biased on, normally-on devices operate more like vacuum tubes in the audio output stage, with simpler circuits that continuously conduct current, resulting in a more tube-like sound. The high-current gain stage is shock-mounted like the TL-7.5, and has been further optimized for linearity, with zero global negative feedback.
Also included in the upgrade are re-voiced audiophile grade capacitors and additional bypassing.
Enhancements to the Series II result in an overall more tube-like sonic character, with more defined images in the listening space, a higher level of inner detail, and a dramatically improved mid-bass and midrange. The TL6.5 Series II is an exceptional match with any of VTL’s other Signature products.
