Wrong speakers

Acid:
S.T.O.P.! Lots of advice being offered, although Zd542's and Unsound's should be heeded. The stuff you have purchased is not cheap, and it is crucial to find the right direction before proceeding. It is puzzling how you find yourself in this position after reading forum info, as Unsound's advice has been the mantra for the 30 years I have been around high-end. But, your situation does give you an unusual advantage in determining your next step. You can take your electronics to a demo location with speakers you wish to hear and audition first-hand. Also, you can borrow electronics (from dealers or hi-fi friends) to mate with your Thiels to test at home. Few of us can have such a perfect opportunity to see which we prefer.

But, your first priority is to get some focus/direction. Crucial to speaker selection are topics I haven't seen you mention: preferred music/instrument types; room size; seating distance; listening levels, etc. Different speakers perform differently depending upon your criteria.

Doing this the recommended way will yield dividends. The other way is a series of expensive crap-shoots.... But, I will say that over the years, I have won in a hi-fi crap-shoot or two (got damn lucky)! It's just that you have this opportunity to really get it right if you use the right approach. Good luck.

Good info. Ceiling height is important to know, as the volume can be drastically different in an 8' as compared to a 16' cathedral ceiling. Big volumes require a lot from both speakers and electronics. Only music type that has me concerned for you is orchestral. I like the ability to fill the room with sound, and in my large room, it takes a big amp with large speakers to make large scale symphonies sound good. Piano can also be concerning, but to a lesser degree, as good piano done right requires balls too, especially in low-mids and bass regions. Hope this helps.
