Looking for my Final Pair!!

Your final pair?
What do you have now?
B’s or C’s?
Don’t over do it. D’s at a maximum. 

I am not familiar with all of those speakers. The Cornwall IV are very high sensitivity. Tannoys I believe are the same. But you should verify if you don’t already know. This is important bc you need to match your amp(s) with these speakers. I will say that if you want that holographic and wide soundstage with imaging and depth, a tube integrated or tube power amp(s) would be the way to go. I am a new convert to tubes. OMG. The above characteristics above are addicting! Sounds like what you want. Plus with even a low wattage tube amp you can drive those high sensitivity speakers with no effort. If you are solid state all the way the high sensitivity speakers will allow for use of a low watt ss amp like a First Watt class A amp. 

What is in the rest of your system? Speakers alone cannot give you what you are looking for. It’s all about the synergy.

+1 on the Magnepans if you have the room and the power. 

Dave_b,  My man there isn`t a  box speaker on earth 12k. or under that reproduces music realistically as though your siting in the Lincoln center in Washington, DC or as you put it at the Village Vanguard.  Just think if you were in a concert hall would the music sound like it was coming from a box?  For heaven sakes no,  I`ve paid 250.00 of my hard earn dollars to hear a great musical it best not sound like its coming from a box.  The acoustics at the Vanguard isn`t that good a live recording the box speaker sound worst.   Once you`ve listen to the magneplanar`s (aka) maggies set up properly you would never ever want to listen to a box speaker again Corwalls, Klips, Wilson Audio Alexia 25k, Martin Logan`s, Gauder Berlina Akustic RC 9`s 75K.  know matter  the cost.  The best box speaker I have ever heard was the Tannoy Golden Seal`s I wouldn`t give up $2.00. for the Golden Seal`s or any other box speaker. For 6-7k you can pick a pair of maggies the 20.1`s  that will just blow you away given you have the room and the right amplification. I`m absolutely blown away with my Maggie 3.6`s (2) Velodyne 12inch. subs the Pass XP30 Preamp and the Pass butt kicking XP 350 Power amp.  If your hearts desire is to be at  the Village Vanguard mentally but actually at home weighing  in on your easy spot listening to your favorite artist follow the advise I promise you you won`t regret it.  I am so in love with magnepans I plan to build an addition on to my home a  35X35X12 room and purchase a Pair of 20.7`s; now if the LORD really really bless me I see the 30.7`s 30k  I`m speaking it into existence as though it is so Hebrews 11:1-10  Stay blessed.
