Duntech Sovereign, Dunlavy IV, V, VI purchase make sense today?

This thread's title-listed speakers received multiple decades of the highest praise.  Such legendary speakers can't just lose such status because of their age....or can they?

I currently run with Sound Lab A1 and Sonus Faber Amati Futura.  But I have an itch to try a BIG dynamic speaker without paying a fortune for such.

I'm thinking about the V, VI or Sovereign.  The dimensions are doable but the sheer mass of these things is intimidating!  A local friend had the IV's for many years, modified the with very impressive results, but them passed them on.

Getting these things down to my basement isn't happening but upstairs will work mighty fine.  Only other concern is driver replacement but there seems to be a lot of qualified driver rebuilders out there.

Amplifier concern is a non issue as I have CAT JL-3 monos and a Symphonic Line Kraft 350 40th Anniversary Stereo amp. 

I will only consider this if such speakers are a day's drive away as I would use a trailer.  What are your thoughts?  A crazy idea in current times?  And if so, what is out there at under $10k that can even begin to touch these speakers' performance.
