The power amp on the Decco is its weak part. I'd look towards speakers with 90db efficiency or greater. Klipsch heritage line or more recent refernce line are two that I would consider.
Also I think the Decco has pre-amp outputs on the back, meaning it could be used with a separate and more substantial power amp if needed. I think a lot of Decco users end up going this way from what I have read.
