Speakers costing range of 2500-3500 per pair


With my budget what speakers would work well with the Denon 4311-ci

Have to ask what your goals are?  Is your priority movies or 2-channel music listening?  If the latter, what are the most important sound reproduction characteristics to you from a speaker perspective?  At this price level for speakers I think you're outclassing your receiver and won't get the best out of what speakers at this level have to offer, unless your plan is to upgrade your upstream electonics fairly significantly in the future.  Don't mean to be a buzzkill here, but without knowing the answers to these important questions it's really impossible to make an informed recommendation for your specific situation. 

The aforementioned Vandersteen 2CE Sig IIs are another must audition in this price range but are not as efficient.
I'd take it even farther, the 2Ce Sig II is a must-audition up $5K. I drove mine to satisfying SPLs with my Ayre AX-7 (60 W into 8 ohm, 120 into 4 ohm). I only heard clipping if I tried to reproduce The Who at concert levels. Anyhow, the 2Ce is superbly balanced in it's price category without any substantial weakness.
Ascend Acoustics Raal Towers. I purchased a set in 2015 @ 2800. I sold them last month. After listing them on another site, within 8 hours I had 6 buyers. It was strange trying to pick which one got them. They sound incredible for the price . I updated to a set of speakers costing 4 times the price of the Ascends. They spoiled me,and I just refused stepping backwards on my updates. Obviously they hold their resale. The reason being its really rare for them to become available on the used market .I originally had them with a Marantz 7500 @ 110 watts. They needed a sub to bring life to the rock and roll that I wanted to listen to. But most people think their fine with out one .Listeners choice .
