Michael, you seem to like dynamics, and sound staging. For a dynamic speaker, the 10Ts have good dynamics, but nothing like your 19s. Slight cracking of the composite mid / high cabinet, is not normal, ime. That should not happen. And yes, they require a good amount of power, but with current, as not every 200 wpc amp has the same current output capability. You have owned many excellent speakers. It will boil down to only one thing. What are the specific qualities, such as dynamics, and / or sound staging, that are the most important to you, and, only you. We are all different listeners, and it would be easy for me to make a recommendation to you, as others here have done. The thing is, no speaker will be perfect ( perfection is non existent ), but each of us needs to determine, what we want to live with, and, what we can live without. You have 2 rooms, so maybe you can set up 2 systems, that cater to your various moods. Reading through the lines, your lines, I believe sound staging, is the most important characteristic you are looking for, although, the 19s ( dynamics ), certainly get your attention. I own highly modified Klipsch Lascalas, and feel, they do most things exceptionally well, for, what I want. Tone, agility ( speed ), coherent, and dynamic. With every kind of music, at any volume level ( I did have two subs built, to match them, for that last octave )They have excellent imaging and sound staging, but nowhere as " large " as other speakers I have owned, and you have owned. What they do, however, is present music, in a very realistic way, that makes listening to many other speakers, sound " dead " to me. The 19s are a wonderful speaker, but my only issue with them, and it is an issue " I have ", is it is a hybrid horn system, and I hear that discontinuity between the bass cabinet, and the horn ( I owned them, modified the crossovers, damped the horns, added additional bracing to the cabinets, the whole nine yards ), but felt dissatisfied. A virtue of many speakers, such as Vandy's, Thiels, and many panels, are their coherence. I am used to Lascalas, which use a true bass horn, which has an seamless transition between the dog house ( the bass cabinet ), the mid horn, and tweeter horn. Of all of the speakers you have owned, I would feel, even with the " coherence " issue I find with the 19s, they would be my choice, because of all of the other attributes " I " find important. I tell you all of this, not to make it about me, or to convince you to get a pair of Lascalas, but to tell you, " I know what I want ". Determine what you want, instead of going on this merry go round, that many here, are on ? And, if you cannot find a single pair of speakers, to do it all for you, well, you have two listening spaces to fill. I would pass on the 10Ts. Again, I did not want to make this about me, but any time someone makes a suggestion to another, it is sometimes about them. Enjoy ! MrD.
