Sorry probably my mistake, wrong model number , when I checked it showed 50wpc. Moreover I've heard that Marantz so its easy recommending.
Tube Amps are a different ball game altogether, people won't consider tube amps for Elac. The Good Quality High Sensitivity Speakers matter more for tube amps, than anything else. Tube amp watts work like Class A, most of them have their own distinct character, even when made from same Manfacturer. Only the Chinese Tube amps sound similar. I'd probably not buy a tube amp unless I have a compatible speaker.
