Reimagining the iconic aesthetic with the cast aluminum chassis of its Electronic remembered “X”the prestigious British musical firm Fidelity has just launched the market X-Tubea revolutionary separating stage (“buffer”) of valve output that supposes the return of a concept of product initiated with the revered X10D. Tuning by Antony Michaelsonfounder of the brand, this electronic singular took its name from the contraction of “Ex (10) Ten- (d) dedication”, respecting the new model faithfully the design of the internal circuitry of the original. Connected between the input source and the amplifier, the X-Tube extends the audio chain acting as a Intermediate stagein order to improve the quality of that and add the tone and dynamics Characteristics of the vacuum valves to the existing line sources in it, read optical disks, DAC’s, network music players and even preamplifiers.
To achieve this goal, the musical Fidelity resorts to a configuration based on Two Triodos E88cc (also known as 6922), arranged in an innovative way by processing the entire audio signal in “Single-Ended”a topology whose correct implementation allows to exhibit a Transitory response superior and consequently manage rapid changes in the volume level with a Minimum distortion. But the valve output stages provide even more advantages from the technical point of view, the first being the Superior entry impedance of vacuum devices with respect to their solid state counterparts, empowering the separating stages to provide a Better adaptation of impedances (especially when used between a preampler and a power stage) and ensure therefore a Maximum power transfer minimizing losses.
In addition, they can offer a high isolation level between the amplification and load circuitry (that is, the acoustic boxes), protecting The first of reactive loads and minimizing possible instabilities or oscillations. Hence its ability to introduce a tonal palette and additional subtleties with the result of contributing depth and wealth To music reducing in parallel auditory fatigue. The X-Tube, whose main chassis consists of an extruded aluminum piece that blinda in front of electromagnetic interference, it is completed with a brushed aluminum front panel and a connectivity Formed by an RCA input, a “bypass” rca and an RCA output.
