With the new TP-2.5i phono stage, we have created an entry to true high-end analogue sound. The VTL ‘family’ genes of highly resolved detail, linearity and controlled bass are all there, along with tonal depth, richly textured midrange and spaciousness you won’t find in most phono stages. For the true music lover seeking to capture the special magic that only a fine analogue system can provide, the new TP-2.5i phono stage is an essential component.
The TP2.5i shares the same cosmetics as the TL2.5i preamplifier with aluminium top and thick sides that mount to a well-braced chassis, offering better rigidity and bracing, and also a non-ferrous loop around the audio circuit.
The TP-2.5i also comes with internal MC StepUp transformers, to offer the user complete flexibility to handle any cartridge. The available settings are MC active, or MC StepUp Transformer, either of which flow through the 12AX7 MM stage resulting in an all-tube path for the MC Stepup.
The MC StepUp transformers at 10:1 step up ratio offer approximately the same gain as the active MC stage, but with far lower gain noise, and cartridge loading options of 100ohm, 470ohm and 1kohm. Certain low gain low source impedance cartridges sound better with step up transformers, and the lower-noise step up means that a very wide range of cartridges can be used.
To further reduce the noise pickup by the step up transformer, shielding between the power supply and the audio circuit has been added, and the AC filter components are now moved to the AC power supply side of the shield.
Another design breakthrough in the TP-2.5i is the use of the shunt regulator in the power supply, resulting in lowered noise floor and opening the soundstage to a wider, more spacious and cohesive soundscape.
The new power transformer in the TP-2.5i is similar to that used in the TL-2.5i, and is designed to achieve a much lower magnetic radiation by utilizing a balanced winding technique.
Multi-stage AC RF filtering ensures complete filtering from AC-borne radio frequency interference, and lowered circuit noise, for a darker and quieter background.
