Hi, the NX5 was produced from 93 - 99, and the NXA was the last of the line, 2000 - 2002, the main visual difference is the nx5 has the single sided s/arm, while the nxa reverted back to a double sided s/arm, like the earlier pre 93 nf5's, but obviously a lot more beefier than the nf5. Iam obviously biased towards the nf5, as i own one.
