Thiel Owners

Proud new owner of a pair of Thiel speakers.  My 2.4's are driven by Classe CA-200 in a living room with sloped high ceilings (about 10 to 20 feet at its apex).  Room is roughly 15 feet in width by 30 feet in length.  Speakers are space about 9 feet apart.  With respect to the room walls, the speakers are placed about 2.5 feet from the backwall and 3 feet from the side walls.  Listening position is about 12-13 feet from each speaker.

Sound is good so far but imaging is a little off.  If I add a cheap tube buffer like FX Audio Tube 1, the imaging and soundstage seems to improve quite a bit.  I'm hoping to experiment with better tube preamps in the near future.

Thanks to jafant for providing many insights.

mrpostfire-
My pleasure.

Wonderful! to read about your scoring a pair of CS 2.4 loudspeakers. 
Experiment with speaker placement as you certainly have the dimensions for best outcome. When imaging is off center try placing the speakers closer to each other, a measure farther from back/side walls or sitting closer 10-12 feet.  Keep us posted as you dial-in these speakers into your system.

What other gear including cabling rounds out your current set-up?

Happy Listening!

Welcome! to this thread. You will find a plethora of solid information to assist your speaker set-up and obtaining the best presentation and sound.

Happy Listening!

mrpostfire - Your room is large, which is great, but its dimensions present some potential standing wave issues. The average ceiling height is the same as the width and the length is double that dimension. That setup is less than ideal.

If there is any way to get your speakers farther from the boundaries, that might help. Also, opening doors is good, especially if near corners and/or center of long walls. As a learning experiment I suggest the following:Your width is fine, although I might try 8' between speakers to give 3.5 to side walls.Length in difficult rooms sometimes works well with golden ratios.
Listening position at 18.5' from wall behind the speakers.Speakers at 10' from wall behind them.That gives 8.5' from speaker line to listening chair.
Or reverse the room end-for-end if better for traffic. 
You are then closer to the near-field with generous room all around to delay the room modes relative to the initial direct sound.

If you can try this arrangement, please let us know how it works.

PW - in the absence of other responses, I offer similar advice as to Mr Fire. The room is a huge part of the playback experience and can often be directly addressed very cost-effectively. Your geometry would benefit from effectively shortening the room as well as convex diffraction / diffusing on the corners, especially where end-wall corners meet the floor. Pleated wool draperies are amazingly effective as is wool / horsehair (old fashioned) carpet under-pad. Let us know your progress.
