The 664 would sound great with almost any ham rig, but it needs EQ, 
because it's a flat mic. The EQ I just recommended for the CM500 is a 
good starting point, but I would add boost of about 9 dB in the highest 
band and about 5 dB in the band below that.

It's a balanced mic, so to connect it to a ham rig, connect one of the 
signal conductors to the rig mic input, connect the other to the mic 
return, and connect the shield to the chassis. No other matching needed.

I don't remember the 630, but my guess is that it would work too, and 
would likely need similar EQ. Since it's hi-Z, it's probably unbalanced.
