New and unused. Selling for a deal at £200 incl post.

You will need a test record that plays a left and right channel tone individually to allow each channel to be dialled in (dialling out the cross talk).

An amazing piece of kit that truly enhances a vinyl system.

Designed by Jim Fozgate.

Details from the web:

The XT-R represents a distinctive electronic approach to solving crosstalk inherent in many turntable cartridges and acoustic problems due to axial tilt. We have placed the name Foz in honor of the XT-R’s designer, Jim Fosgate. Jim (Foz) Fosgate’s life long career in audio design represents decades of work on every possible circuit approach to car stereo, surround processors, tube amplifiers, preamplifiers, phono preamplifiers and other accessories. This wide array of designs have all been explored in depth, built, and auditioned by Foz. In coupling Foz’s XT-R design with Jolida’s decades of manufacturing experience; the result is a unit which can provide our customers with a distinct improvement in turntable sound reproduction at an affordable price.

To obtain high performance from a modern phonograph system, the tone arm and pickup cartridge must be properly adjusted to within a few thousands of an inch to minimize the effect of axial tilt. Axial tilt is when the cartridge needle of the turntable is not perpendicular to the record groove. In addition, a low dB channel separation of the cartridge can result in crosstalk. Crosstalk is simply the stereo signal from the left side leaking into the right side, and the stereo signal from the right side leaking into the left side. Phono Cartridge crosstalk has a great effect on sound stage depth and width, as well as the position of sounds across the stage. When the crosstalk is “in phase” on both channels the stage width and depth will be reduced. When the crosstalk is “out of phase” on both channels the stage will be wider and deeper. When azimuth is off the crosstalk on one channel will be “in phase” and the other will be “out of phase”. This tilts the stage to one side or the other and effects the positioning across the sound stage.

Foz has designed an elegant electronic circuit to effectively reduce crosstalk and axial tilt. The XT-R represents a breakthrough since axial tilt and crosstalk is compensated for electronically and does not use the traditional approach of physical adjustment to mitigate the problems. The XTR incorporates signal cancellation to reduce inter channel crosstalk. This is the same technique that is used in high separation surround processors. The XTR corrects for a misaligned stylus or cantilever, misaligned generator, misaligned tone arm azimuth (axial tilt). It also reduces crosstalk from cross coupling of the generator coils or tone arm wiring. This works with moving magnet, moving iron, and moving coil cartridges. The XT-R will compensate for up to 7 degrees of axial tilt and can improve crosstalk to a maximum of 40dB. The result will be an improvement in stereo imaging.

Got another for sale, new and sealed in it’s box. However can’t do it at the same mega deal.

£260 incl U.K. post.

Recommended and likely the easiest LP to set the XTR up is ‘The Ultimate Analogue Test LP’.
