Black Ice (Jolida) Fusion F159 Phono Preamplifier - New (Open Box)

Description

Selling a Black Ice Audio (formerly Jolida) Fusion F159 phono stage - Brand New (Open Box) and never used. Purchased as a gift but was never given (a long story).  Item was taken out of the oroginal box and packing materials ony once.  It is in perfect condition and includes the power cable, original box and cover, and test LP for setting up your cartridge. Black Ice’s Audio F159 Phonograph Stage Tube Pre-Amplifier is an example of state-of-the-art vacuum-tube technology as it exists today. This product was designed to provide:
- A Phono Stage that would deliver musical accuracy
- A significant value based on a high performance to price ratio
- A vacuum tube unit that would exceed the reliability of solid state units
The F159 is housed in a heli-arc welded chassis and uses 2 6922/6DJ8 tubes. Parts quality is the best currently available, and the overall circuit layout is maximized for sonic purity.  Another major feature of the phono stage is the inclusion of the XTR circuit or Cross Talk Reduction circuit. To obtain high performance from a modern phonograph system, the tonearm 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.
Jim Fosgate, has designed an elegant electronic circuit to compensate for crosstalk and axial tilt. The XT-R represents a breakthrough
since axial tilt and crosstalk is not mitigated thru the traditional method of physical adjustment, the compensation of the XT-R is electronic. The XT-R incorporates signal cancellation to reduce inter channel crosstalk. This is the same technique that is used in high separation surround processors. The XT-R 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 circuit 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 channel separation to a maximum of 48 dB. The result will be an improvement in stereo imaging and clarity without any sacrifice in
smoothness.
