To the best of my knowledge, the M1, F1, and R1 are Oyaide's Premium Products Beryllium line. However, while the M1 and F1 shells are no holds barred, cost no object designs, the R1 shares the same body design as Oyaide's rather affordable SWO Ultimo AC outlet line.

The P-004 and C-004 are Oyaide P/C AC connector line models. The 004's are more affordable versions of the M1 and F1, since the 004 shells share the same design as the other P/C AC connectors (046, 079, 037, 029). While the 004's do have the same platinum (0.5) and palladium (0.3) plated beryllium copper blades as the M1 and F1, the 004 shells are the same as the P/C AC connector line, which makes the P-004 and C-004 much more affordable than the premium M1 and F1.

Exactly , the top Oyaide models are all 1's - hotbird 00:45:01 07/04/07 (0)
If you want the best and money's not the concern, the F1/M1/R1 are the best-performing matching triplets, followed by the P/C004s

....and further, to split more hairs, other than the color, the R-1's build is identical to the other Ultimo's. One could rename them Ultimo Models 1, 2, 3, and 4, which might have made more sense.

And excepting the beryllium copper substrate, the 004's are no different than the other connectors, albeit with differing platings.

Which is why I suggested a mythical shootout between the like-plated innards with differing, higher-performance shells. This would take a certain amount of labor, along with a good amount of listening time.

  First, BeCu is great stuff for sonics. I've had it in some ICs made for me and they're a head above silver or copper both, IMO. So when they came out with this as the substrate as an improvement on the usual copper or bronze stuff, then I was quite excited (sadly, my pocket was depressed!)
  
  Second, Acrolink uses carbon fiber in those barrels, I think. I got the idea for CF experimentation from that and those of us who have been playing with CF sleeving of plug barrels are happily impressed with the results.
  
  So I have a hunch that I can give the probable answer to your questions without the experimentation, but I cannot afford the experiment to prove or disprove that.. LOL
  
  Any manufacturers out there who'd care to take up my challenge? Oyaide and Acrolink, wanna send me the goods to test this out? I'm waiting....

    Indeed....materials matter. As do particular combinations of materials, and I have been espousing the concept of materials interaction (in high-end audio performance) for many years. Much of our success, and failure in creating component synergy rests with these interactions, some (I believe) even on a nano level. What you're doing, bart, is where the rubber meets the road.
    
    And yes, the Acrolink barrels are made of machined aluminum and carbon fiber, addressing both resonance and noise issues. I could take a good guess at the outcome of the comparison as well, but I wanted to suggest further experimentation (by individuals) with the possibilities. The cabling used with the connectors contributes to the materials interaction as well, additionally adding their own resonance signature (per Al Sekela). Particular "recipes" seem to be better than others, and the beat goes on.

      Alan, you wrote: "...where the rubber meets the road." Are you hinting at rubber now? LOL
      
      I've used rubbers in my youth, but they simply dull the experience.
      
      Hey, true story of my first lesson in electronics in Jr. High: I asked the shop instructor how you were supposed to tell the "male" from the "female" connectors he kept mentioning. He sat down on the front of his desk, made an almost fist with one hand (hole through the fingers meeting the palm), took the other hand's index finger and inserted it in and out of the hole. Wry smile on his face, you can bet!
