Hi Charles,
The RB250 is a fine arm but the Audiomods Classic 3 will be a significant improvement on it.
You'll notice the superior bearing quality the 1st time you hand cue.
Wiring & counterweight mods can improve the RB but the Audiomods is a major redesign
with only the arm tube left, which is the Rega's strong point.
I did something similar a few years ago & was surprised at the overall sound improvements.

I can't speak to the differences between an AM arm and a Rega arm, but if upgrading the arm and/or getting the existing arm rewired, I would try to make sure the shielding on the arm cable is as good as possible.

I know that sometimes Rega arms have less than ideal shielding on the stock cabling. If you check some old threads here you may find some topics on cable shielding.

I had a question about cartridges for the Reflex, I am getting a clearaudio Air concept with carbon fiber arm. 
I Really am torn between getting a clearaudio artist 
Moving magnet or the New Sumiko Bluepoint, I know the 
Bluepoint Evo iii pretty well and used it with a project RPM-9 
With Graham Amp 2SE and loved its fleshed out
Spot lit character as a HOMC, but is the clear audio 
Possibly better or have better synergy with 
The arm and the phono stage? Any help would be appreciated 
By the thread.

The Bluepoint carts have been around a long time. Made by Excel, IIRC. If you know you like them then they are a good bet for you. From what I can tell the Evo series was discontinued and now Sumiko is mainly selling the Songbird as a replacement. They still have the Blackbird which may be similar to the Evo series. IIRC the BB comes in either high or low output.

The Artist moving magnet cart looks like a typical CA MM job where they are scant on detailed info but are really just using an AT VM95 or 95 series generator with "elliptical" diamond then stick it in a wood or metal outer shell. My guess it is a cheaper bonded diamond, since they don't mention that it is nude. If it were they'd be harping on that fact. I'd rather just buy a cart direct from AT so you know exactly what you are getting.

In terms of the arm could you be more specific? Looks like CA makes more than one carbon fiber arm. There is the standard one which is 9g and the "Satisfy" which is 7g effective mass. They have more arms still. I would choose a fairly compliant cart on the lighter one. On the 9g arm you could go either way, but I'd probably avoid any cart with a very stiff suspension when it comes to either of these arms.

It is a satisfy Carbon Arm

I plan after the purchase to get Stack Audio
Auva EQs as well if that info interests you.
 

Yes the blue point is still made, they now have it in 
A covered aluminum body and have damped the resonances 
More so it’s the same old cart as the EVOiii but
With better dampening. I’m afraid the blackbird is no more
I wanted that cart for a long time about 17 years ago. 
And I’m not sure I like the songbird.

I think the clear audio artist cart is made by them with AT
Parts and it could be a VM95 generator but they wind 
Their own coils there so my guess is they are modifying it 
Significantly and of course adding an ebony shell, 

The current bluepoint iii does look a lot like an Umami
Blue by Excel, I think though the Bluepoint may be better 
In terms of channel separation and frequency range alone than the Clearaudio, 
I was just wondering if the Clearaudio 
Artist was particularly good with A graham Slee phono stage 
Since obviously Graham’s stages do miracles 
With moving magnets. 

Thanks for your advice

This one?


Effective mass is 7g.

OK. Odds are it's not that much different than whatever they were selling years ago with the same Excel generator. If you know you like the cart already, then it should be a safe purchase.

A simple test with a multimeter to measure resistance and inductance would tell the truth. As for "winding their own coils", with an MM cart, that is highly unlikely. Virtually no one hand winds MM carts or high output MI carts because there are too many winds of coil to do. The process is usually automated and done on a machine. Of course dealer/salespeople will talk a lot of bunk so maybe that is where you heard that. I wouldn't buy it for a second. LOMC carts are a different story and usually have to have the coils hand wound. Of course those have very few turns of wire in the coils. 

As for CA's "mods" when the carts have been taken apart and the diamonds put on a microscope the truth is revealed. Their basic MM carts are nothing special and have cheap diamonds on them. The higher end ones usually have much better diamonds and cantilevers but they are often murky about what you get. Lot of marketing talk and bunk in the cart world with very few companies actually making cartridges, cantilevers, and diamonds at the OEM level.

Excel is the OEM for those Sumiko HOMCs. Sumiko is just a brand name/marketing company. Excel makes MC carts for several brands and has for decades.

The Artist will work. Not a particularly good value in my book for the reasons stated. If you want an alternative I would be looking at the AT VM500/700 series, Ortofon OM or 2M series, maybe Nagaoka. Any of those should match well with your CA tonearm. The AT 500/700s will be trickier to load electrically for the best frequency response...I recommend short low capacitance phono cables and parallel resistive loading for those.

The Blue Point will also work. Western compliance at 10Hz will be much higher than the Japanese 100Hz spec as seen in tests done years ago by Miller Audio Research...

Yes that is the tone arm, the satisfy carbon 
It’s the main one that comes with the concept air, 
Other than the tracer which is more expensive.
 

I appreciate your feedback, I know Prima Facia 
Evidence seems like the clearaudio cart is just a rebadge 

If you watch Michael Fremer or pursuit perfect systems factory
Tour they show them doing coil winding at clearaudio they do make LOMC carts with original parts, like the Goldfinger. 
As far as what’s inside them maybe it’s to hide proprietary methods of modding, maybe it’s that they are just taking these carts modding the exterior and doing very exacting matching, or 
Just rebadging and rehousing them I don’t know. I’m not fond of AT carts except their LOHC and I’ve been told by people their carts do in fact sound different than ATs, but I digress. 

As for excel and Sumiko my guess is Sumiko is also designing carts as well I don’t think the Hana stuff and Sumiko carts sound the same, I don’t like Hana carts till you get to the umami blue or even red. At which point I would probably buy a gold ring ethos anyway, that cart is sort of my end goal.

Thanks for your input I will go with the blue point iii
And hopefully the new one has improved a bit since the 
Evo iii version

All the best…cheers.
