Keep the speakers that move you.
I used VOTT's in the summer of 1975 (Mac/Dynaco tube gear in a large room with very high ceilings) and aside from their warts/blemishes they made me smile.
Watched a YT video of yours in which they sounded better+++ than what I recall of mine.
This said, having listened to the new Heresy IV and the new La Scala on YT soundbites (yes, I know YT supposedly sucks for auditioning purposes) I'm intrigued.
Could not stand either models in their vintage versions, but the new ones...
Aside from not having the real estate for the big ones (and also that I would not invest that amount of money in speakers) the Heresy are a problem as I could keep my current system and use them in the living room setup.
I liked the H's in the same manner that I like my vintage wide band single drivers, but they offer "more" of what I like in a single/simple package.
This said, I may be better off ditching my tube gear and going with a simple SS integrated mated with conventional speakers considering my age and the fact that I no longer gave the energy/ability to fuss with HiFi gear as I've done/enjoyed in the past.
Hope this makes sense as I suspect that we may be going through a similar "event".
