Duntech vs Dunlavy?

Rcprince, at least until one year ago Duntech gave support to the old Sovereigns, and also they tell to me that this model is still in production and in a very competitive price.
My Sovereigns are biamped with a digital amp (Yamaha MX-D1) for the bass and a tube amp for highs (ASL Hurricane). His sound is really good but as I never heard a big Dunlavy (very rare in Europe) and I always ask to me if they will sound noticeably better.
Recently I bought a pair of crossovers, from a younger Sovereign than mine (but with the same drivers), and I'm working to put better components as Mundorf caps and resistors... I hope that this upgrade will give a more open and detailed sound to this good speakers.

Pryso, I have personal messages from other goners that also believe that the Duntech are a overall better product.
As I told before I, have a mixed amplification: tubes/digital, and I should add that I have also an digital active filter (BSS-336) but only in the bass path, in order to adjust the SPL of the woofers and correct the room modes. For me (and many of my audiophile friends) the sound is very smooth and detailed, with fast and clean bass, but with the big and focused soundstage and, when required, with the high dynamics and SPL that this speakers can produce.
