Although the room is 45' x 15' , it is separated into an eating area, a sitting area, and a listening area(15'x15'). However, the ceiling is slanted and high and the separations between the areas is achieved with partitions only. The listening area is well damped with curtains and thick carpet.
Currently I have a pair of magnepan 3.7i driven by a pair of sanders magtech mono block amplifiers. These amps are rated to 2000w into 4 ohms and I have to be careful not to blow the fuses on the maggies . Preamp is a Schitt Freya +. The sound is superb. Until I set this system up, I really didn't know what people were talking about when they said they could 'see the instruments'. Positioning the maggies 5' away from the back wall is no problem but they cannot fill the room. I added a pair of rhythmic subs and the lower end is better. The imaging does require proper positioning and seating. You cannot really have a good listening experience unless you are in the sweet spot. That limits the experience to two people sitting really close. In addition, they are big and now with the subs, I am getting dirty looks from the boss of the house.
So I am looking for a pair floor standing speakers that can stand up to this room but that might be less imposing. The walls have heavy curtains, thick rug on the floor so echo is very well controlled. I listened to the B&W 802D but found them harsh (I don't remember the amp that was driving them) I have looked at (but not listened to) the Golden Ear Triton reference as well as the Triangle Magellan reference and the Gershan avant garde. I would like to keep my amps and preamp.
I mostly listen to vocals, jazz standards, and folk acoustic although I also put on some ambient when I am reading, cooking, etc. I am getting on in years and have noticed fall off in my ability to perceive the upper frequencies but still enjoy listening.
Which speakers would work well with my amps and this big room? I am looking for a bigger sweet spot (soundstage?) , more presence to fill the room a little better without losing the clarity, the realism and the quick response (articulate?) of the maggies.
