$3000 stand mounted speakers?

Thanks Meiaflask. Your story of your journey has good information for me. Looks like my initial choice of the ProAc Model 10 or upgrade to the Model 10 Anniversary is still a solid choice for me. Its 10 ohm rating is easy on tube amps and slightly better bass is a better match than the Harbeth P3 I thought about.

I’ve used my Seas Froy mk3 speaker kit w/ 3 different EL34 amps over many years and it has worked quit well, but it’s time for a change. I like the look of the Tablet 10 very much and would like to ask what you get w/ the Anniversary version.

BTW Meiaflask, My amp is the Mystere IA-11 by PrimaLuna. It’s more dynamic and punchy than a PL w/ the glorious EL34 midrange. So you comparison is important to me.

Thanks Taww. The other speaker I’m most interested in from this long thread is the Dynaudio Special Forty. I’m wondering if it may work w/ tube amps, and it seems like it may be a better speaker for Bryston amps or similar according to your assessment.

Tekton Impact Monitors.  Incredible speaker and value.  $2k delivered.  Check out the review.

I can’t get past the look of Tektons. Looks way to busy to me drawing your attention to the speakers. I like a more subdued look. Not only does a $3k speaker have to sound good, it has to appeal to my visual senses too.

Wavetouch because of the value and most natural sound, as well as the universal positive reviews.

I went through a similar Journey a year ago. However my room is much smaller  @ 13 x 15 . My list had a number of speakers already listed. Including Dynaudio Special Forty ( loved the Contour 20 much better  Maybe used $3500). ATC SCM 11 or 19 , Proac Response D2 or D20R ( not sure if bookshelf) , Legacy Studio, Fritz Carrera BE. I also included Acoustic Ariel 5T, PMC IB1S Studio Monitors or the Twenty 5, Focal Electra 1008BE , Selah Tempesta. My goal was to replace an older (20 yrs)  Sonus Faber Concertino . I was also looking for a great price on the SF Olympica 1 ( used) . Only heard a few of the speakers live when a used pair of Monitor Audio Platinum 2 became available locally . It has incredible highs and an outstanding firm base response. The base was so good I no longer needs the SUB for the music I play  . I am shocked at how big they  sound and fill the room . They soundstage is very wide. Literally blew the old SF's away - not surprisingly given the age and cost difference . I use a 36 watt Tube amp and maybe max at 11oclock on the pre without them being much too loud yet still sounding very clear .  I thought I would need more power . 
With a large room I think you will need to be much more selective . Even with a SUB it will be hard to fill the room . I know you are looking for a Bookshelf Speaker but there are some lovely and great sounding floor standers with a small footprint . Maybe a used Totem Forest Signature for a room that large.
