“Let’s start with the latest version of the well-established TL-6.5. Wedging the full feature set and functionality of the company’s two-box flagship line-stage into a single chassis was no easy feat, requiring a vertical extension to the established casework used for the TL-7.5’s PSU and control section. The resulting box can be supplied in silver, black or two-tone mix, the latter making the most of the original’s elegant design and front-panel proportions. On the inside it houses a fully balanced and differential circuit built around a single pair of ECC82 tubes, used for the critical voltage gain. Paired with a sophisticated FET-buffered, high-current output stage, you could argue that this should be more properly described as a hybrid design, but frankly, I’m more interested in the performance than the labels. With its large and highly regulated power supply, what the 6.5 does is deliver the coherent dynamics and presence that make tube pre-amps so musically appealing, combined with an incredibly low noise floor and the ability to drive almost any load – both extremely unusual in a tube design. Even more unusual is the functional versatility, with a full suit of balanced and single-ended in and outputs, processor and tape loops, adjustable overall and individual input gain. Look inside and you find a mirror-imaged circuit, precision resistor ladders and more by-pass capacitors than you can shake a stick at. The package is topped off with a sensibly sized, full function remote and a display that you can actually see from across the room.”
