The Sanders 10'es are probably one of the best speakers of all time. I have always loved electrostatics and planar and ribbon speakers. I have loved Quads, Apogees and Magnenpans . and other ESL's. but the 10e's are a step up.

The quads are beautiful speakers  and I love them  but the 10e's hybrid  design makes up for their bass deficiencies, I also love the Maggies - planar magnetics. The newer Maggies use ribbon tweeters but in my opinion not up to a true electrostatic

I have the luxury of a number of high end systems.. I have home theatre system of Maggie 3.7s .with centre channels coupled to a subwoofer and it is great . I have a home theatre system with Paradigm speakers and subwoofer - great moving watching, 

I have  soundlab ESL system - fantastic sound but limited extension. If I had to pick one it would be the Sanders.

Additional thoughts and comments:

Electrostatic speakers have always been a bit contentious. People tend to love them or hate them. I respect their position as I have explored a lot of electrostatics, planars and dynamic speakers. They all can be great, so the opinions expressed are my own. I have no affiliation with Sanders or any other commercial interest. The opinions are directed at expressing my experiences and perhaps clear up some myths surrounding electrostatic loudspeakers. This is also to express my experiences with Roger Sanders, his company and ESL, in general. 

For me, this dates back to the 70's. I listened to many speakers but ESLs always blew me away - Quads etc. They were not in a price range I could consider. Then Roger published articles in Audio Amateur (that are still available on his website) to build ESLs. These were way over my electronic capabilities, however subsequent articles pushed me on. I contacted Roger and is these were in the day that proceeded communication via internet he walked me thru the process. This was pretty primitive in retrospect. The ESL Stators were garden panels from a hardware store. The diaphragms Mylar with rub in graphite and the power supply a photocopier power supply. Pretty primitive, but sounded great. Coupled with transmission line bass (also home built ),  I upgraded my system with new amps And I was experiencing arcing in the electrostatics. Arcing has always been an issue (perhaps non issue) with ESLs, I subsequently figured out the ESL were just fine the highly regarded amps simply weren't capable of ESL capacitive loads.

As I had torn apart my original DIY ESL’s, I went shopping not wanting to a rebuild. I had heard the Eros were great. Roger was his worst enemy :-) He taught me to build ESLs so I did a rebuild.  They were equally stellar.

So as I get old I sold off my home builts to downsize. I didn't downsize and missed the ESL's so I got the 10's 

• Firstly, ESL panels. Some suggest ESL panels may be unreliable. This is a myth. I ran 2 home built systems. ESL panels for over 20 years. Neither was replaced by panel failures and I believe the new Sanders ESL panels are even more reliable plus they are warranted for life. Few Dynamic speakers can match that record.
• Second, are the electronic crossovers, which are superior to passive crossovers. In addition, the room correction software that is available for most home theatre systems is inferior to Drive rack systems that are used with the 10's.
   
• Lastly, are comments as to bass.
  As Roger and I are in accordance with ESL we have an equally agreement as to transmission line bass. Transmission lines are difficult and expensive. This is why you will have little luck in finding speakers that support this. My last iteration of home built speakers had bass and midbass modules. The bass drivers (12 inch Dynaudios) and midbass modules ( dual Dynaudio 6.5 inch drivers) fed to 8 to 12 foot transmission lines These speakers are 7 feet tall and have 0 Wife approval. That Roger is able to come close to this performance with a single aluminum driver is an engineering feat.
   
  So to the myths:
  • ESLs are unreliable - been running them for 30 plus years with never a panel failure.
  • ESL's are too directional. they are directional and in that role they are magnificent. but for off axis they still rival conventional speakers.
  • ESL's are demanding loads- they definitely are but as with any speaker you need to match your amps to the load.
  • ESLs don't provide dynamic range - This is true for most full range ESL,s however hybrid systems address this issue.
  • ESLs don't address listening rooms. There is no question room interactions are extremely important but a flat plain electrostatic because of its directionality minimizes these issues.
  • Curved electrostatics are better - maybe not. Perhaps a better off axis response but at the expense of detail. imaging' coherence
