I heard an extended session with the
ATC SCM-7's (the babies in their line) and was I ever impressed. The wee wonders are/were $1100.00 a pair

and need lotsa' power to drive them. With a hi-current YBA amp driving them, they sounded beyond superb. Fair bass extension for their size, rock solid imaging and it all hung together like no bookshelf I've ever heard.
It blew the
Quad 11L's away that I heard on the same day...and they are no slouches (I ultimately bought the Quad's as I didn't have the power to drive the ATC's and my budget, at that time, was stretched at the $700 for the Quad's). My Dad has the Quad's now....and they sound very fine in his den. I can recommend them heartily especially used well under $450.
My current speakers are 10 year old
Linaeum Tower models (rewired, and acoustically deadened with 20 lbs of Plast-i-Clay and lead shot and Acousta-Fil fibre in each and added Tekna-Sonic Vibration Absorber to the rears) ...and I owned a couple of the Radio Shack branded Linaeum's before. They're all good....but stick to the 4-6.5" woofer'ed units....the 7-8" pairing with the incredibly fast Linaeum tweeter don't jive together well enough. The LX-4 and LX-5's were great for likely that reason.
The Linaeum tweeters on the Linaeum-brand speakers are a little higher end than the Radio Shack counterparts...whether it was the bi-pole or monopole versions.
I've found over time that
mass = pleasure with speakers. The smallest cabinet size and the heaviest weight for it's particular size
normally add up to one heckuva' good sounding speaker. It's easier to make a more rigid bookshelf sized cabinet than a floorstander, and less expensive as materials and labor are less, so I'm a bookshelf lover at heart...currently in love with a floorstander.
Go figure
