Or
I could go with the Mean Well 48V which would take care of both power and transformer.

Is that correct?
Just to be clear, the Antec PS-5N42 is a transformer. I pretty certain from the description that the Sure IRS2092 needs a full power supply. This would be a linear PS consisting of some thing like the Connex board + Antec PS-5N42. Class D Audio's Heavy Duty DC power supply HERE, plus the Antec would also work.

Reading the Sure IRS2092 blurb more carefully I see that they recommend +-50 to +-65 VDC so the 48 VDC Mean Well would be marginal.

I think I am going to go ahead and order the Sure board as I do really want to get all my speakers up and running.

Also, do you know of any instructional videos or how to step by step instructions to assemble the 254 from Class-D audio? This is still the week point of these kits.

I have ordered a couple electronics books and have began reading them. I think I am going to be fine but it is totally different than wiring homes;>)
Thanks Feanor
I really don't know whether the switching or linear supply would sound better. Purists do lean to a linear supply, however.

To be "safe", just go with the Class D Audio CDA-254L kit, Class D Audio CDA-254L Kit - Amplifier Kits, or the SDS-254 kit. It comes with adequate instructions to connect it up.
