TL 2.5i Performance Preamplifier
The TL-2.5i all-tube preamplifier is designed for performance – giving you music that is direct from the source, in the most realistic, colorless and truthful way we know how. This preamp is packed with features to give you the maximum control over all the audio and video sources in your system. With 6 line inputs, an optional internally retro-fittable phono stage, two pairs of outputs, a tape loop, and external processor loop (for home theater), you can rest assured that this preamp will plug and play into your existing system in no time at all. Silver or black cosmetics, and remote volume control and mute come standard.

This new and improved version of our long-standing TL-2.5 Performance Preamplifier, both the line stage and the phono stage have been updated sonically with audiophile-grade parts, resulting in improved resolution, greater harmonic richness in the mid and highs, with the speed and dynamics that have become the hallmark of the VTL family sound.
A pair of user-selectable Gain Switches have been added to the Line Stage to allow the user to select between Normal Gain and Low Gain. Similar to the design of the TP-2.5 Series II Phono Preamplifier, the TL-2.5i’s internal phono stage supports both MM and MC cartridges, and offers user-adjustable Load and Gain settings that makes cartridge optimization an easy task for vinyl lovers.
Above all, you’ll be pleasantly surprised when you find out how little the TL2.5i costs. This sturdily made unit hand-built in the VTL factory in California, with proven-quality parts, will take your breath away with its clear, musically involving sound.
