Look at all these different preferences or suggestions. The answer is very simple. Once you get into a relatively large circle of speakers for any set of circumstances (dollars, room size, etc.)...it's Taster's Choice. We all listen and prefer differently...there is no definitive or wrong answer.
What is the best audiophile speaker for a tiny square room?
I currently have Soundlabs M545 electrostatic speakers in my 9 x 11ft room. They are great speakers particularly for this small room because they are more directional than box speakers and therefore decrease sidewall reflections. However, like other electrostatics, they are hard to drive and require big amps (>200W), which tend to generate a lot of heat. Class Ds don't go well with ES speakers. Are there great easy to drive speakers that would work well in this room without compromising SQ?
