Non-fatiguing speakers in $10K range?

Unfortunately, there are not that many high end shops around Seattle with gear I like. Some went selling vintage and some went up selling only $100K+ systems. So most probably will be getting something blind.

I haven't read the entire thread, so perhaps someone has already suggested this, but you should visit Gig Harbor Audio if you haven't already.  The owner has a good ear for the type of speaker you're looking for and they carry a number of lines of British type monitors - Harbeth, Graham, Rogers, as well as high sensitivity speakers like Devore.  

You might also consider joining some local audio clubs - we have one here in Olympia that meets monthly and Seattle has one.  

I have been through a fair amount of speakers and keep coming back to Harbeth.  I currently have the Harbeth Compact 7ES-3 in my main system in a fairly large room.  They are the 30th Anniversary edition, not the current XC model.  I have also owned the Super HL5 Plus and have the P3ESR along with the Stirling Broadcast - LS3/5a, which is almost identical to the Super HL5 Plus, but priced lower.  I've also heard the Harbeth 40.2, which are amazing and could be found pre-owned in your price range.

I like speakers that are neutral and easy to listen to, but have detail, great midrange, and excellent imaging and soundstage.  I am very sensitive to anything that sounds "bright".

My room is fairly large, but I listen close to nearfield, about 9 feet from the speakers.  I have had larger speakers like Klipsch Chorus and Legacy Audio 20/20 in my room, but they were too much for the room and didn't image like smaller monitors do.  

I've had the Compact 7's in my system since the end of March.  My original thought was that they would probably end up in a second system, as I have KEF Reference 1 speakers and didn't think anything at or below their price point would be better, but I have not had any desire to put the KEFs back in the system. 

The KEFs are marvelous speakers that perform way beyond what you might expect from something their size.  They produce a remarkable amount of bass for a speaker of their size and while not super efficient, are relatively easy to drive.  

Some other options you might consider are Joseph Audio Pulsars or some of the small Gershman Acoustics speakers.  Vandersteen are also a good recommendation.

@mikhailark , I have to apologize for getting your amps mixed up - somehow I was thinking low-powered Class A Pass Labs, when it’s actually low-powered (but not as low-powered) Class A Accuphase. Speakers with a voltage sensitivity at least in the lower 90’s still make sense to me given your room size, because imo clipping on the peaks would degrade the sound quality.

I owned a pair of Accuphase stereo amps years ago. They could be bridged to run as two very powerful mono amps, but they sounded better in stereo mode. So imo it is quite possible that, despite your amp’s extraordinary ability to maintain full rated power output into very low impedances, it will sound its best into an 8-ohm load.

I mentioned PiSpeakers, and you mentioned measurements. My favorite from their lineup is the 7Pi, which is an innovative corner horn type speaker that actually has excellent measured response. It would probably need subwoofers so that pushes the cost possibly beyond your price range, but if you appreciate innovative, outside-the-box thinking, you might take a look at it.

Just to be clear, I have zero commercial interest in Pi Speakers. I compete against them.

Based on the sound description of these, it may be what you are looking for

You can always take a nice ferry ride (or drive around) to Silverdale and see Jim & Aubry at Nuts About HiFi https://www.nutsabouthifi.com/manufacturers/ (big on Focal) or Kitsap Audio and see Derek or Victor https://silvercityhifi.com/pages/our-brands (Victor is worth the trip alone). Olsen's has previously been mentioned (Marty's a gas). Fun place and always have some deals going on!

I can recommend 2 things for $10k that will be excellent.

An open box or demo Yamaha NS5000 speaker is great and unique in that it is a cone speaker with all 3 drivers made from the same material. That makes a big difference in the coherence of the speaker. No other cone speaker has that design. The cone material is called Zylon and is like Beryllium but not bright or toxic.

I used to own the Meze Emporium headphone. I then went to the RAAL SR1a and CA-1a. The new RAAL 1995 Immanis as incredible but expensive at $10k. However, these are competing against phones in the $50k+ level.
