Hey jrwaudio,
I’m certainly open for you to share your thoughts on speakers that you have considered in the past. What I find a little odd is that if you are aiming towards ML’s, are the speaker you have tried in the past not living up to what you expect from ML’s, (which I already have)?
My wife and I love our Spires, we will not give then up until we can find something better, which I think will be pretty difficult on our budget.
I would actually purchase new unit first, before letting the Spires go just to ensure they sound equally as good. The focus for me being on something smaller and more efficient.
With regards to the listening position. My existing room is only 12’ deep. With the speaker 2 1/2’ of the back wall and my chair, a pushed up against the step down into the sunken living area, my ears are around 9’ away from the speakers and it sounds pretty darn good to me.
I find if you abide by ML’s flashlight method in setting up your listening position, this general rule works pretty well from any reasonable distance.
I was running a pair of GoldenEar Forcefeild 4 subs and wound up selling them as I found the bass on the Spires perfect my listening experience.
