Stacked Large Advents v Cornwalls v Klipschorns

I am quite familiar with all three.
1) Klipschorns
2) Cornwalls
3) Distant third - Advents
The Khorns are amazing if you have the correct room for them, but the Cornwalls are a really enjoyable all-arounder, and an easier fit in more rooms if less exciting dynamically. They're still superior dynamically to the average good direct radiator.
In my opinion, the Advents are just too old, and I don't think they are really even in the same league as the other two.  

Thanks. I appreciate your time.

I have heard all three of them and stacked Advents are hard to beat if the woofers have been serviced correctly. I have owned 4 Advents since 1974 and I went through them a couple years ago and when people hear them they cant believe how good they sound.

Anyone that says negative things about Advents don't know what they are talking about. 

I have owned all three of these speakers and correctly refurbished Advents in a double stacked setup will give the other a run for their money.
