Recommendations"I have to say the Rega modifications turn this humble arm into a real Giant killer. Gone is the rather grey, sterile sound of the cooking Rega. Instead, tonal colour is fresh, dynamics have great speed and impact, and the sound stage is huge." Rega tonearm mod review with RB300 and RB250 - Hi-Fi World (Nov 97)
"In short, the performance boost was striking. The most obvious improvement concerns scale. With the modified arm, the stereo image is much wider and deeper. Focus, enabling each musician to be placed with accuracy within the sound stage, is better too. And improved bass depth increases solidity and weight. In fact, there isn't an area in which the standard arm betters the modified. Dynamic swings are faster and tonal colours far more vivid, making the standard RB250 seem almost grey by comparison." What Hi-Fi? (Sep 98) gave the modification a 5/5
"The overall musical and sonic performance of the Origin Live RB250 is simply astounding. Considering its sub-$500 price, the only appropriate reaction is to yell, 'Eureka!' The Origin Live modification of the RB250 appears to be the new giant-killer." Rega arm mod review on RB250 - Stereo Times (Aug 2000)
"If you have any…Rega RB250 or 300, dismount the arm and send it off for the mods NOW. You have no idea what you are missing." Rega tonearm mod review on RB250 - TNT Magazine
The structural modification entails reconstructing the rear end of the arm on which the counter weight is attached. This is an extremely critical area, as the counterweight represents by far the highest moving mass in the arm and affects any tonearm’s performance more than can be imagined. The work involves removing the rear end stub which is normally just screwed into the end of the arm and replacing it with a new stub, which is then torqued onto the arm by a thin high tensile bolt. The stub is also designed such that it presents a low contact area onto the arm tube and is therefore decoupled, yet far more rigid than the original. This also allows the counterweight to be rigidly torqued onto the stub using an Allen bolt. On an unmodified arm, the counterweight must not be rigidly coupled in this way due to the poor vibration characteristics of the standard arm / rear stub joint. This ingenious Origin Live modification elevates a good tonearm into the same league as the super arms and at an insignificant outlay. This mod applies to the RB250, RB300, RB600 and the RB900 in fact a modified RB250 will still comfortably outperform a modified rega RB300, RB600, or RB900 tonearm - see FAQ on rega tonearms for reasons why.
It should be noted that the structural modification to the rega arm is far more significant than any rewiring of the rega, even though rewiring the tonearm is known to do wonders. Rewiring the OL1 arm yields particular improvements to bass weight and transparency. |
