LOUNDSPEAKER FOR $10,000.00 PER PAIR

Most of what we are going to say is mirrored in other threads to which we have replied here is our take on this subject.

There are a lot of good speakers in this price range, you need to identify what are your priorities aside from just bettering your current speakers and these issues include things other than just sound.

1:Are looks important? 
2:Is the loudspeakers size important?
3:Is the long term sustainability/servicability resale important as some of the smaller companies may or may not be around 10 years from now
4:Do you prefer to purchase new and gain dealer/manufacturer support or is used a viable option?

Then determine sonic issues, the Golden Ears and the Golden Ear Reference are not the last word in detail, like it or not Golden Ear uses good well made drivers and parts but these drivers are not state of the art in design compared to more exotic and expensive European drivers so a Heil AMT is not a Heil AMT. 

We were going to be Golden Ear dealers and had the Aeon 2 left at our shop for a few weeks the speakers were good they were not amazing compared to the LS 50, we brought in the Quad Line the S2 which uses a real ribbon tweeter and those sounded amazing and could challenge the LS 50. So one Chinese sourced and built ribbon vs one Chinese sourced and built AMT are similar equations. 

Considering you have 2 excellent subs, you may not need a speaker with very deep bass, so in terms of what you want to get superior dynamics are usually from bigger more robust designs however the dynamic ability of a speaker also comes from the electronics and your tube amplifiers are probably not the last word in kick.

So with this in mind you need to be a bit more specific in what you are looking for these are the questions we would ask you about the sound:

1: How loud do you like to play?
2: How important is imaging, do you want a big wash of sound or is the specificty of the image more or as important.
3: How much resolution do you crave? Sonic flavors run from the warmer camp: Vandy, Harbeth, Proac with soft domes, Golden Ear, Legacy, vs the more detailed camp, Paradigm Persona, KEF,Focal models like the Kanta, Rockport etc.
4: Are you prepared to buy without listening as some of the choices listed here may not be demoable unless you drive or fly to a larger city.

Hope this helps give you some guidance on to some of the things you may need to also consider.

Bondmanp, Omni directional speakers are a love hate thing, honestly most people don't like them, if they did everyone would be making such designs at last count I think there are four such designs: MBL, Ohm, German Physics a Walsh clone, and the Candian Electrostatic product.

The issue with omni directional speakers is the image is very large and very unfocused, also the sound may be bouncing all over the place due to reflections, over the years have heard most of these designs, give us a direct radiating loudspeaker which is tunable anyday.

Soix so far heard the Carvers at several shows and they just didn't sound right to us at all, where did you hear a pair sound good, most of the show reports haven't been flatering.

Salk does make some very interesting designs with very good drivers, howerver, if detail is your thing, a pair of Paradigm Personas offer a pure Beryillium midrange driver and tweeter so the sound if very coherent and the Paraigms are quite dynamic and image extraoridinairly well.

The Salks use a ceramic midrange driver with a Raal ribbon two very good but different sounding drivers, have heard ceramic midrange drivers over the years they all sound slightly hard in the midrange, although they have great detail, hence Kharma moved away from ceramic for this very reason. 

The other issue with a company like Salk is actually hearing a pair because they are factory direct means no dealers and hence difficult to audition.

Drive or fly to a big city and you most likely can hear Kef, Paradigm, B&W, Magico Rockport, Wilson. etc.

Kji if it is possible take an audio vaction to NYC and you can hear almost every conceivable reference speaker you would want.

Prof it is impossible to properly tune an omni, the effects of toe in do not apply to such a design, and for most people roon reflections will create a wide but unfocused image as you will be producing new sound sources via reflections, a well damped room and the right place in the room is crucial.

Have heard MBL many times over the years, they are one of the best of these types of designs, howerver, yet to hear a set whose image is believable most of the times the image is too large and lacks the pin point focus of the really good dynamic designs. The Mbls do have very good clarity and are very open which is a positive.

EBM  Magico is a another love hate brand, many people find the Magico's boring and lifeless, also will they really work well on a tube amp, most Magico demos use high powered solid state.

We haven't heard the new A3 which may be tuned differently.

With a tube amp the great matches have been the Focals, Legacy, the Persona 3F from Paradigms are also amazing with the right tube amplifer. 
Tektons would also work.

If the OP has GE and wants more clarity then a speaker with higher technology/better implimented drivers will be the key, most of the less expensive Chinese sourced Heil drivers or Ribbons or Planner Ribbons Hybrids do not have the upper octave detail, we had the same tweeters Carver used in our much more expensive Scaenas and they did not have amazing detail, slightly soft in the upper octaves.

If the OP craves more detail then the Sopra 2, the Paradigm 3/5F should be on the top of his list.
