If you say they sound incredible with what you have, I agree with the other fellow, enjoy!. Incredible is pretty hard to beat. I'm still trying to get the top of the line OMD's to sound incredible.

so you are gonna use the Onkyo as the pre?

I know I'm way late on this...but hopefully I can help. I've got the OMD-28's and love them. For power, I'm using two Emotiva 500 watt/channel Monoblocks (XPA-1). Plenty of clean (cheap) power. That being said, I am toying with the idea of adding a tubed amp and preamp into the mix. After about 15 minutes (warming up) - the XPA 1's sound wonderful and warm.....hence the reason I am really debating hard to introduce a tube amp/preamp.

Mbovaird the OMD 28's require lots of current. I'm not confident that a tube amp will deliver unless you plan to spend quite a bit for one.
