Onlywax,
The Decware Zen amp is a unique creature. It can sound stunning with the right speakers, but it can also completely fail to power some speakers that would typically be considered "good with SET". I know, I've tried one with my Reference 3A MM DeCapos (SET friendly) and the little amp actually "puked" at only moderate volume.
I have a couple of friends that are huge Decware fans and their systems sound fantastic. However, both of them use speakers that were designed to be used with the Decware Zen amp which actually prefers a 2 ohm load.
Recently Decware has come out with a version of the Zen that is designed to drive 8 ohm speakers. Also, some of the other Decware amps may be better suited for 8 ohm speakers.
I would highly suggest that you post on the Decware forum for information. There are some good folks there and they will give you good advice about matching the Decware amp with Omega speakers.
Enjoy,
TIC
