Don't fool yourself, there is a lot involved in making high quality cables 
than just crimping on a couple of plugs.

I haven't seen his connectors, so I can't say if he is using the "right" 
connectors or not, but I do know that I've been buying AMP brand MMJ plugs 
and I have genuine AMP tooling. The junk crimper he bought off of eBay is 
a knock-off of the non-ratchet Ideal Telemaster. Anyone who has done much 
in way of cable assembly knows how poorly those type of tools preform. 
Short term, a cable made with that type of crimper might test ok, but it 
isn't going to produce the consistent crimps that the AMP crimper does so 
it may exhibit problems later.

I'll admit that I do tend to put a lot more time into making cables than 
most people do, but I want something to be 100% reliable (when used under 
reasonable conditions, of course).

To quote a late friend of mine, and I believe Tony has also said this a 
couple of times:

   I can't afford cheap tools :)
