Need Small Bookshelf Speakers With a Big Sound

Wow, thanks for all the recommendations!  FWIW, in a couple of coincidences, I went to Holm Audio to hear the KEFs.  While I was there, I also was advised to listen to PSB Imagine Minis, which I liked, but seemed to need a subwoofer to fill out the sound.  So I wonder if the slightly larger PSBs would be a good all-in-one alternative.

I also listened to a pair of Tannoy floor speakers there, although my wife decided she liked the "lighter" look of smaller bookshelf speakers on stands, than taller floor speakers.  Appearance is very important to her, and I think I can find speakers that sound good to me if they fit her "blend into the woodwork" eye.  Lots to check you.  Thanks for the ideas!

chiguy,about a year ago I had to downsize from Sonus Faber Toy Towers & SimAudio i5.3 integrated amp.I wanted the absolute best combination in my budget range of small size & big sound as replacements,they had to sing with lowish powered tube amps(10wpc.+)& as these would probably be the last pair of speakers I would ever buy they had to look special.
I went through 3 pair of Dali’s,long demo’s of Martin Logan Motion 15, 35XT’s,Focal Aria 905,906’s & my VERY hard earned $ went for the Made in Denmark, Dynaudio Excite X14’s in Satin Tiger Rosewood finish on Pangea DS400 stands.
Do yourself a favor before you drop coin & have a look at the physical size of all the speakers on your short list & the baby Dyn is smaller than them all.It has the ABSOLUTE most beautiful finish of any of your choices & in either the Rosewood or Walnut finish they can stand next to the finest furniture.
My room is 4mx5mx 2.5m & with a 10wpc.single ended Class A tube amp they can ROCK Judas Priest Metal Gods until the walls shake!They never drop below 7 ohms impedance & have a very mild Phase Inversion Angle so every watt goes straight into driving the speaker.The crossover is designed to eliminate early floor reflections so they integrate easier into areas with reflective floors.Lastly the sound is IMO superb!Driven by a 25wpc.Class A EL84 tube amplifier it has everything I required in a speaker.Tone,texture,imaging & sound staging is all there & present in spades!You can feel the resonance of a cello being pushed,the difference between the dull thud of a plastic bass drum & stretch of skin,horns have bite but are never brittle or hard,closely miked vocals are so perfectly portrayed you can hear the parting of a singers lips just before the first notes sing out.Bass is just amazing & hits a solid low 40's in my smallish room & after hours long listening sessions absolutely no listener fatigue.You do yourself a disservice if you don’t give the Dynaudios a long look & listen...

"Check out the Harbeth P3ESR or the Spendor 3/5r2. I have owned and enjoyed both ! The fit and finish on the Harbeth's are outstanding!"

and then

"Forget the speakers that I recommended, not for the type of music you listen to!!"

Are you sure they wouldn't be appropriate for rock music?  They looked nice online and got very good reviews.

If you really dig through all the P3ESR reviews as I have you will find several references from listeners who have stated they just don’t rock...IMO based on fit & finish/price ratio they are also WAY overpriced when compared side by side with the Dynaudio’s!!!

You might want to consider the Gallo CL-2 from the Classico line.  It looks like the Classicos (which meet your decor requirements) might have laid an egg commercially.  Gallo dropped the prices a fair bit and Underwood HiFi was discounting them, too.  Last I looked, they were under $1k per pair.

The key here is the very wide dispersion Gallo tweeter, which gives their so-equipped models something of an omnidirectional feel.  It's got a 5 1/4" ish woofer in a ported box, so bass isn't going to shake the walls, but it's satisfyingly full.  

If you want big sound from a small speaker, this may be a good choice.
