i'm falling in love for this..
does someone have it? what's your opinion on this job, is it well worth the money of the DIY kit over a new-different tonearm? |

Well worth doing, definitely transforms the rega to a whole new performance level and Jeff is a real gentleman to deal with.

have you listened to this tonearm? how does it compare with other similar priced tonearm?
don't those holes reduce stiffness? |

Oh yes, I have had a long test of one of these on my own design of turntables.
The holes help to break up the resonance in the arm and have no effect on the stiffnes.
At its price you really can't go wrong. You could look at Jelco or Pro-ject but the audiomods arm is a real hand made bargain.

I found the most cost-effective upgrade to the RB250 was the Origin Live counterweight assembly - the counterweight and mounting stub are replaced with new components (a very simple job) and increases the rigidity of the whole arm without changing the arm tube....

Actually, the most cost effective is to simply put a RB300 stub and counter weight on it. All of the same benefits, a fraction of the cost. And I think I am right in saying that even the very elegant TecnoWeight is better value, not least because it eliminates the absolute need for a VTF balance or scales. 
However going back to the Audiomods Rega, this is a new arm from the ground up. Only the arm tube and a couple of other minor components survive from the original arm but it is favourably priced compared to the obvious competition. The arm has recently won an award in the press so we can assume it sounds as good as it looks. I have seen and heard one in the flesh and preferred it to the much more laid back RB900 I was running at the time. The version I heard had the micrometer built in for adjusting VTA. |

I tried this on RB250 and an RB300, along with an original heavy weight, OL weight and Tecnoweight. The stock RB250 weight noticeably coloured the sound, the RB300 stub and Tungsten weight were much better but I eventually settled an RB300 with the OL weight over other combinations.
With a different cartridge on a different turntable (and different ears?) the decoupled Tungsten weight may perform better, but to my ears the extremely rigid OL design is the best, and a bargain despite the poor finish.

I just got done reading the 10 page paper on the design objectives of the Audiomods upgraded RB250 and RB251. Audiomods does indeed do far more work on the Rega tonearm this side of the Origin Live Encounter MK3 which only retains the arm lift lever I believe. I have not heard this tonearm but after reading the paper, I would consider this Rega upgrade over any other. Given it's reasonable price, it seems like an extremely good bargain. I encourage everyone to read the 10 page paper. The education will not hurt you. |

I am hoping that my arm will ship this week. I ordered it without the micrometer.

Hi Todd,
Yes I'm (just) on schedule to finish the arm this week.
Base etc. is all done and I just finished the arm tube this evening. It's got a few little "tweaks" in it to suit your cartridges, like a some extra mass added inside and three bracing disks.
Looking very nice, I think your gonna like it.
Just have the mounting plate for the Samba tt to do and then wire it.........
cheers, Jeff |

Hi Jeff,
Thanks for the update, I am looking forward to seeing your arm mounted on my Samba tt. More importantly listening to how much more I can get out of my cartridges with it.
If you don't get it finished this week it is no big deal to send it out next week. I added the mounting plate to the order after you gave me your estimate.
This arm with a brass counterweight is going to look sharp on my tt.
Regards,
Todd |

Hi, yes that one has the Technics mounting. I really like the look of that one.
The owner wanted to use one of the Ortofon Nightclub cartridges  A 7cu cartridge in a 5g body. I'll never complain about Denons again 
So that's when I developed the idea of putting extra weight inside the arm tube to get the effective mass up. Took about 9g for the Ortofon!
Just a few g in yours but it's what cartridges like the Shelter need to work well with Rega tubes.
cheers, Jeff |

Well perhaps I should have said "most of the benefits". |
