DIY Rega arm conversion kits


Series Five arms

A new generation
With almost 700 examples of these hand-built arms in use and a reputation for a level of performance that can be compared with some of the most expensive tonearms in the World, you will find Audiomods arms partnered with very exotic turntables and cartridges.

While we’ve continually made improvements to quality and performance this is the most significant upgrade yet. The Series Five arm has been designed around Rega’s new generation 202/303 arm tube casting, their first major revision for 30 years. The most obvious change is the new, redesigned arm yoke. The two bearing caps are now machined as a single unit, linked with a thin, solid bridge, which encloses the arm tube in a complete box section.

What isn’t visible is the new bearing carrier and shaft, hidden within the base, with the bearing shaft set up into the arm yoke, an even more rigid structure than the previous versions. The result is greater bass definition, improved imaging and better retrieval of fine detail. .

" arm that will outperform anything at remotely it's price level…"
"….one of the finest arms you can buy regardless of price…"

“The degree to which you can hear what's going on in the mix is quite remarkable and the way it combines this analysis with musicality is extremely engaging.”

“…amazing value for money and offers some of the finest engineering you will see on any tonearm.

“I am going to make this short and sweet. If you own a Rega RB250 or RB251 or are considering a tonearm in this price range, I cannot think of a better choice than the Audiomods tonearm.”
Nels Ferre, Enjoy the Music

"This is audiophile heaven. Does it work as well from a music lover’s point of view? The flow is beautifully modulated, supple, ductile, sensuous and balanced."
"...a very classy-sounding arm and an exciting prospect for people looking for close to super-arm sonic capabilities at an affordable price."
Edward Barker, Six Moons.

New look, new finish
Series five arms come with a new, matt “frosted” finish as standard (Polished finish is still available to special order) and stainless steel or optional gold plated counterweights. The finish adds a hard compressed “skin” to all the surface which contributes to the improved performance. As well as being functional, the new finish is the perfect compliment for many modern and classic turntables and it also resists finger marks, keeping the arm pristine for years to come.

...and some well tested principles
The performance of any arm depends upon how accurately it can be set up, and to help get the best from the Series Five arms we include tools for precise cartridge matching and adjustment including a new variable-mass counterweight and a set of headshell shims. The heavier shims are of annealed copper and will suit cartridges of low compliance and light body weight. The light alloy shims will fine-tune many moving coil choices. The new counterweight comes with removeable copper shims to adjust its mass and position for optimum performance.

As always, each arm is made to order, individually numbered and packed in a wooden presentation box. The Series Five arms are also available in a standard (non-micrometer) version, still with built-in vta.

...and the future
Will this be the final development of the arm? Very likely not. Analogue reproduction can always improve and there is always a little more to be had from a record groove so the design will continue to evolve. We will continue to offer a future-proof upgrade path for all our arms so any of our products can be updated to the latest specification.

A new model at a very special price
This new arm bridges the gap between the Audiomods DIY arm kits and the full Series Five arms and offers a very similar level of performance to the top models.

If you have a budget but don’t have the tools or skills to build up an arm from a kit, this is the ideal solution: a complete, ready-to-play Audiomods arm with performance that has been reviewed against arms of four times the price and one that won’t be out of place with some of the most exotic turntables and cartridges.

The Classic is built to the same standard as the Series 4 arms and uses new Rega factory 251 parts for the arm tube and arm lift with every other component machined from solid billet. Each hand-made arm is individually numbered for the owner and comes with comprehensive instructions and setup tools.

Complete wiring loom
The wiring loom is a single run of Cardas 33g wire from the Michell silver-plate cartridge tags to the phono plugs, wired in a “pseudo-balanced” configuration in the same way as the Series Five arms, with a separate ground connection, and a screened 0.9m interconnect section.

Choose original polished or Series Five matt finish at the same price.
