I am going to look for some measurements of the loudspeakers but LEEd are not common, I actually heard them being demonstrated at the Munich show fifteen or so years ago, they are worth a look if you are not familiar with them.
Question is would you say the Leeds are being properly driven by the Resolution integrated?
Thank you in advance,
Keith

There is no web information about the Leed H E2 Loudspeakers. I attempted finding details and stuff but to no avail. If the amp's output wattage is linear'ish then the 50w/ch will seem like more. Otherwise it might be a bit low going off of the speaker efficiency, my gut feeling and previous experience with amps and speakers.
Re: Sensibilité : 83 dB / 1 m / 2,83 v
It's a unique amp for sure. I've never seen a ground terminal for speakers before this. I almost thought it was bi-amp'able with the blue color of the speaker negative terminal.
