A friend of mine had both a Graham Phantom and a Basis Vector arm on a Basis table. He much preferred the Basis Vector with his Orpheus cartridge. I preferred that combination too, though this sort of judgment is very system specific. A friend in the industry (a distributor) also much prefers the Vector arm generally, and particularly with the Orpheus (he thinks the older Graham arms actually sound better-more alive).
Another friend uses the Orpheus in an SME 309 arm (with upgraded bearings and the dampening trough) and gets really good performance out of that combination. I also have an Orpheus (the more current low output version), which I have on a Basis Vector arm. It is a very good sounding combination, though I could say it is better than the Lyra Titan that I also have (the Lyra is a bit leaner and more open sounding on top, the Orpheus has a little more upper midrange presence).
I don't think that any reasonable generalizations are possible. While it is hard to actually get a chance to review cartridges or tonearms, actually hearing a combination in one's own system is really the only way to actually tell what is ideal for a particular system and particular taste. I have heard really nice vinyl setups with such a variety of arms and tables that I think one can make any reasonable combination work well. The choice of particular cartridge and phonostage makes much more of a difference, to me, than the choice of arm and even table(I have heard cartridge/phonostage combinations that, no matter what was tried, just could not be made to work together).
