Speakers with wide listening window


I am looking to upgrade my speakers (currently Paradigm Monitor 7 v3). My biggest complaint about the Paradigms is their thin optimal listening window. If I am out of a narrow corridor directly in front of them, or if I am listening more than 4 ft off the ground, the sound drastically depreciates. I realize that all of this is inherent to some degree in any 2-channel system, but I am generally active and moving around while listening to music (e.g. while cooking) so I'm really looking for a set of speakers that can fill a room (20x30x10) without needing to be too loud.

My budget is about 1500 (up to 2k, max) new or used. The rest of my (vinyl only) system is:

Clearaudio Virtuoso Cart
Marantz 15-TTs1
Onkyo A10 integrated amp

Thanks!

I do something similar to what AK is saying with my Dynaudio monitors to make them perform more similarly to my more omni OHMs in one of my rooms where I have the placement tweaked for off axis listening.
I would seriously consider the Shelby+Kroll Nano monitors. I've had these now for almost a week and the soundstage is phenominal, it just follows you around the room. I was even listening behind the speakers and didn't notice a significant difference and mine aren't even completely broken in yet. I've been listenting to mine with a cheap Yamaha receiver and can only imagine how much better they would sound with better electronics.
I would contact Tim over at Shelby+Kroll They may have some B stock remaining. He's a great guy to deal with and I doubt you could do much better in this price range.
Ditto: look at Ohm. You get a 4month in-home trial; if you don't like them, you're only out the cost of shipping them back. Whether or not you like their presentation is a matter of personal taste, but they're definitely worth a look. Very well priced, too.
Try towing your speakers so that they cross in front of you.
This works very well for the AV and HT listeners.
It allows the soundstage to image in a much wider spot so everyone on the couch can have a bit of imging.
It's free.
