I've spent plenty of time with the ETs and the Sols. The ETs do need plenty of current. As pointed out..they also need to be away from the walls maybe 3 feet or better. Other than that if setup properly they sound very good. You can adjust the treble on these speakers. The midrange and treble have that airy box less sound you expect from a planar. The woofers integrate pretty well(better than MLs). The further away you sit with in reason the better(maybe 10 to 12 ft) with hybrid speakers. This gives the drivers time to blend before the sound reaches you.
The Sols also need to be out in the room. Since they're rear ported.The Sols are very efficient and can be run off 25wpc no problems. I wouldn't use the Sols in a already "Bright room". The speakers can and do have some spikes in the upper frequencies. Not to take anything away....The Sols do sound good in their own right.
It would be nice if you could listen before you buy.
If I had to choose.. I would go with the ETs. It is a very laid back speaker in comparison to the Sols.
Good luck
