Where to get XLR male to male cable

Why would a preamp output to amp input use a male/male?
Standard connection would be a male to female.

I was thinking that, too.

I’m no techie but I believe XLR cables are purposely made with a male on one end and female on the other. Check the labeling on your equipment, output on one component should go to input on the other. It may sound silly, but it’s an easy mistake to make. The cables are made to support that format. Classe Audio equipment is very clearly marked. Be sure to check carefully.

For some reason, the XLR connectors for my Classe Audio DR-8 amp and DR-5 amps both need male connectors.  It does not make sense.  

Below are links to pictures of my equipment so you can see for yourself. I am thinking the DR-5 pre-amp should have the female connector, but it doesn't.  Was this is a mistake when the unit was made?

You’re right, the pre and amp both have female connectors. Since the amp is so old (no warranty issues), why not change out the connectors?
