Speaker for Threshold amp and preamp

This combo will drive most reasonable speakers. The questions for you are - How big is your room? What type of music do you listen to? How loud do you listen? How much time and effort are you willing to spend on proper set up? Do you have any sonic preferences? And, what is your budget? With answers to those questions you should get some meaningful recommendations.

Well, you've heard some good speakers that you can't be sure that you would like. Whether you like speakers a depends largly on how they integrate with your room and the electronics you use to drive them. So my question, rhetorical if you like, is underwhat circumstances did you hear and not like those speakers you referred to? Personally I'm fond of the Tyler Acoustics Linbrook Systems one piece full range system (lots of post here on Tyler speakers), Spendor 100's, and Paragon Jubilee/Jems (which are very hard to find). I think the Tylers have the best quality/price ratio and for a large speaker are easy to set up in a medium sized room.
