Speakers costing range of 2500-3500 per pair

Yes I did and they sounded amazing, like I mentioned in the prior post my only concern is will they sound the same with my Denon 4311.

Yes.  I have heard them on lower end Yamaha receivers and they sound great.  Also have heard them on an old old Onkyo receiver, newer anthem, and a higher end Marantz.  All sounded great.  (I have recommended these to several friends so have heard multiple setups)

Is it worth the extra money to get the Aria 948 over the 936?   How much better/deeper bass do you get?

As always, are you talking brand new or used?  Used, you can get almost twice the speaker for the price.  Browse floorstanders on Audiogon between your two budget points.  If it's got to be new, latest version of Vandersteen 2.

Get something of high efficiency. The Focals have decent efficiency on paper, but not so much in practical use. Check out the Monitor Audio Silver 300s, they’re more efficient, less fatiguing and simply better speakers.

The aforementioned Vandersteen 2CE Sig IIs are another must audition in this price range but are not as efficient. Their 1Cis are efficient enough and competitive in the $3K class.
