I'm looking to use a Sigma 25 @ 250mA to power several components and it only has one terminal + and Gnd for output. How do I hook this up properly to two or more components? My guess is a terminal strip, but I'm unsure it would do the trick.
A double row barrier terminal block is a convenient way to hook up multiple things. That's what lurks inside my active crossover/balanced line receiver box. Use crimped or soldered fork terminals. You can put two under a single screw if you flip the bottom one over, and if you need more than 4 connections, there are flat metal links available to tie adjacent terminals together.
Alternatively, maybe you can drill the holes a little larger and put several wires into one hole. Or drill more holes. Or, splice wires and insulate with heatshrink. Or build individual regulators on point-to-point terminal strips, perfboard, prototyping board, or one-off PC boards.
Or, adopt the connectors used in PCs for fans or 3.5" drives. You can scrounge stuff from dead computers. Those won't make as solid a connection as the screw terminal blocks and fork terminals, unless you order gold-plated versions of the connectors from somewhere like Digikey.

Yeah I've found this barrier terminal... I'm looking at B with 4 positions... Not sure what accessory on the 2nd row would work...

I ended up calling Molex tech support for help. The way to do this is with a barrier terminal with 4 positions and 2 rows. Then 2 of these jumpers -- http://www.mouser.com/ProductDetail...UN6gUIhQo6yTz2FZC3MaiIcgXzaGk5zQdDQYIPRYvTw==
It will basically allow for 2 adjacent terminals to become one circuit (+). The other 2 terminals are the GND circuit. You could hook up 1 positive V supply and hook it up to 3 other circuits.

I like the barrier strip - Molex idea. A nice tidy way to distribute the power to multiple points from a single source. Thanks!!
Glad I could be of help and also thanks to dangus for offering some hints on what to do. I didn't want to have to have a separate power supply for each component (clock, re-clocker, dac) and I didn't want to have to solder all these wires together. This should save some frustration.
