Rega upgrade packages for all eras of Rega turntables

Rega RAGE 3 -Funk Firm FXR-2 tonearm, Bo!ng isolation, Achromat + Houdini -

Rega RAGE 2 -Funk Firm FX5X tonearm, Bo!ng isolation feet and Achromat

Rega RAGE 1 -Funk Firm FX5G tonearm, Bo!ng isolation feet and Achromat

Convenient packages for Rega owners called RAGE 1 and RAGE 2.
Rega turntables are mounted on a single plinth with no suspension to provide isolation from external vibration. The arms have no VTA adjustment making them harder to use with non Rega cartridges, spacers are required which lift up the arm base, and this causes the lid to touch the counterweight! The standard arms also ring and give quite an artificially bright sound.
Regas are ideal for upgrade with our simple to fit solutions to solve these problems.

Background to upgrade packages
The objective of a good turntable design is simply to spin the platter at the right speed and accurately read the information from the record! How well it achieves this is dependent on the turntable’s ability to deal with vibration. 
The focus for upgrades, then, should be to reduce the distorting effects of vibration. Ideally the only vibration occurring during vinyl replay would be the stylus in the groove and the sound from the loudspeakers, but unwanted vibration comes as a consequence of these and other external and internal sources.
Isolation from external vibration– turntables can vibrate due to sound from the loudspeakers, people walking (or dancing!) across the room, and to a lesser extent, seismic vibration from passing traffic, trains etc.

To cope with external vibration, most expensive turntables have a spring isolation system, rather like the suspension in your car. These turntables have two plinths.  The top one houses the platter and arm while the lower plinth holds the motor and three or four springs that isolate the top platter. These turntables are expensive to manufacture and often require considerable tuning to set up properly.
Rega turntables have a single plinth (usually made of MDF, sometimes plastic or foam) with motor, arm and platter all mounted directly to it. This is done simply to save manufacturing costs and does nothing for performance! Rega turntables benefit greatly from a spring isolation system, which can elevate turntable performance considerably with little cost outlay.
For this reason Funk Firm designed the “Bo!ng” spring isolation feet. These screw on in place of the existing hard rubber feet which are ineffective at isolating the deck from the seismic vibrations that are all around. Bo!ngs are customisable to the weight of your particular turntable and are supplied in sets for the turntable in question (three for Rega, four for SL1200 and so on)

Isolation from internal vibration
Platter resonance- if you tap the platter, it rings!  What is happening during playback is that vibration from the stylus itself passes downward through the felt mat, hits the hard surface of glass and is immediately reflected back up again, to distort the movement of the stylus. 
Achromat is our patented solution to absorbing vibration energy from the critical interface between stylus, record and platter.
Achromat contains thousands of randomly sized bubbles. These absorb energy and turn it into heat, significantly reducing the back reflection from the platter to the stylus, and thus distortion. This results in a more 3D soundstage and better delineation between notes. Achromat also helps to damp the ringing of metal and glass platters as it is affixed to the platter when fitted. Achromat is also anti-static, unlike the felt mats that come with turntables. 

Tonearm upgrades
Arm resonances– a tonearm is like a see-saw, a weight at one end (headshell and cartridge) and a counterweight at the other end with a pivot between. Vibrations pass back from the stylus at a whole range of frequencies into the arm, reflected back by the counterweight, causing the arm to bend and twist variably at different frequencies. This colours the sound as the bending of the arm moves the stylus relative to the record.

FXR-2 design
We wanted to upgrade the ubiquitous Rega RB250/300 family of arms to improve performance for the millions of audiophiles who already have Rega arms.

The modifications:
* The non-linear magnetic anti-skate (bias) is replaced with a linear and hence more accurate falling weight design

* The bearings are upgraded to the highest possible quality (AEC7)

* The resonant arm tube is replaced with Funk’s new thin-walled high stiffness aluminium tube fitted with our F.X carbon fibre cross-section beam inside, considerably increasing stiffness, and reducing ringing from 20+dB to just 6dB. The audible difference is startling. Carrying out this modification is a precision, time-consuming task. The end result is not “Just a Rega”, it is a genuine transformation.

Funk Firm FX5 series arms: 
Based on the original F5 arm, the new FX5 series al use Funk’s new F.X braced tube and so have a family performance. The differences are merely in their applicability to different turntables: 
FX5T (Thorens), FX5L (Lenco) are drop in replacements, with no lift or arm rest. 
 FX5G is Funk’s most affordable complete arm and comes with a simplified arm rest and lift mechanism. It is used on Funk’s Gett!.
 FX5X is the top specification variant. It has a solid base for the arm rest and proprietary lift mechanism as well as Funk's calibrated tube with variable mass sliding weight to apply tracking force.
* FX5 series arms are characterised by very low colouration to deliver an open sound, bettered only by FXR and FX3

* Adjustable Azimuth and VTA are standard

* Medium Effective mass
