Xindak XA8250 MKII Reference Pre Amplifier - Type UK | Pre Amplifier | Audio Emotion

Product Description

XA8250 MKII is a dual mono design, pure Class A amplifier pre-amplifier with a separate dual-channel architecture which of course partners beautifully the XA8800MNE and MNU, but has been tested at length with numerous high end power amplifiers, and has shown itself to be a quite sublime match, releasing the full untapped potential of the amps in question.

The special input stage adopts the TOSHIBA HiFi Dynatrons A970/C2240 to promote the upmost symmetry and integrity of the signal path, which in turn is perfectly synergistic with the 'double-difference' amplifier circuit design - this topology allows the XA8250 MKII to punch significantly above it's weight.

This design architecture also connects one resistor in serial with the emitter of each dynatrons - this circuit applies a current 'negative feedback', which in turn decreases open-loop distortion, and vastly improves the linear dynamic range - the result is astonishing musicality and an enthralling soundstage.

The voltage amplifier stage also adopts the complementary push-pull amplifier circuit design and again consists of the world class A970/C2240. The signals are then directly transferred to the output stage giving 'shortest path' advantages and therefore greater signal integrity.

The output stage adopts the pure Class A push-pull arrangement, with the output model consisting of N-type and P-type JFETs - this has two huge advantages of increasing dynamic range and decreasing output impedance - this again ensures the match between the pre-amplifier and other power amplifiers is world class.

The left and right channel power supplies are especially designed for the task and ensure these are separate and isolated. The left and right channel circuits are geographically located at opposite ends of the chassis with the power supply lying directly in the centre, this ensures zero distortion and this engineers in the lowest possible noise parameters. There is also a separate and bespokely designed 40W high-quality E-type transformer with a clever stainless steel shield cover to supply power to each channel. This 100% avoids any magnetic interference to the signal path. Power supply filters and decoupling designs are provided by Marcom and American Military-Grade electrolytic capacitors - optimized grounding is also used, to ensure very high signal to noise ratio's.

In addition, the XA8250 MKII provides separate balanced input and output terminals for left and right channels, this is also a fully balanced design, so ensures the very best performance levels.

The XA8250 MKII is a full Class A pre-amplifier and uses JFET transistors at its heart - this results in a tone which is both natural and transparent.

The sound of the XA8250 MKII is wonderfully balanced in the entire whole frequency spectrum: exquisite at the high frequency, organic in the medium frequencies, and deep and controlled in the LF's.

A wonderful preamp

While it's true that there will never be a component that satisfies every persons unique preferences when it comes to feature sets or even what constitutes as a great, musical sound!

Well for me, the introduction of Xindak XA8250 preamplifier has taken my system to another level be it digital or analogue. There is a gut punching confidence with the combination of Xindak XA8250 and Xindak A600E's that hits one with an absolute immaculate top to bottom "rightness".. The palpable 3D imaging, layering and vanishingly low noise floor "blackness" is intoxicating. I'm swimming in a dimensional room of sound with a big smile on my face my listening room is awash with beautiful music.

Yep, another tour de force from the masters at Xindak. Before anyone shells out 10's of thousands on amplifiers do yourself a big favour and demo Xindak amplifiers at Audio Emotion..

Once again a Big thanks to Gary, all the staff, and especially Steven and Gordon for their invaluable help.

A real winner !

Thanks so much to Audio Emotions for introducing me to the 8250 MKII Pre - from the moment I put it into my system I knew it was something special. The performance is quite exceptional with quite gorgeous sonic characteristics that make it stand head and shoulders above previous pre amps that I have owned - the other aspect to it is just how quiet it is - even with no music playing and the volume up loud, there is not even the faintest hiss , very impressive. The sheer delight of being able to listen to any genre of music and have it presented in the most beautiful way is what makes this special for me - one quick point is that don't use the standard black power lead, as upgrading this allowed me to get its full potential, and that potential is glorious !
