High Efficiency Speakers Your top 3 or more

Has anyone mentioned Zu speakers yet? The ones I have heard have sounded good and I believe around 101 db/watt. The Essence was cheap and sounded good on Atamasphere amps.

As Mapman alluded to these can play modern music without strain too amp permitting.

If somebody can show me a SET based system that can deliver Radiohead's "In Rainbows" with the authority and rock solid iron grip in the low end that I hear currently in my system running the (not so) big Bel Canto Class Ds, in a typcial sized listening room, I will be gladly convinced.

Zu speakers rock, especially the Definition and Presence models with the powered subwoofers.

I won't comment on whether they sounded good to me.

I don't think there is a standard unless someone else knows of one. Early in the thread I set a limit of 92db at 6ohms minimum so as not to exclude anything on the cusp. However I think most of us would agree 92db is not really high efficiency. I think I personally would classify 92-96 db as higher, and 97+ as high. However if your reference is horns that may be low.

MMike84,

Is it a safe assumption that you are looking for different speakers to go along with your tube gear? You aren't looking to replace the amp you have with a SET are you? That makes a big difference I would think on what speakers would work well. I don't think you need super high efficiency speakers necessarily with your amp. I would think 89-90db and a smooth 8 ohm load more or less is all that would be needed for your stuff to sing!
