For years I was a big fan of Dynavectors.
Started with a DV23rs, and wound my way up thru 17D2, 17D3, XX1L ..... then topped the lot musically with a 10X5.
How weird is that?
But the 10X5 remains the most enjoyable Dyna I owned.
You do get a bit more detail out of the propa Dyna MCs, but there's a rambunctious, lolloping sense of fun and sheer enjoyment with the 10X5 that won me over.
I'm also a big fan of the Denon 103, especially when rebodied in a nice massy lump of aluminium. I ended up with a Zu 103 after owning a standard 103 and loved it. It's a great way to extract more detail and refinement out of the bundle of musical fun that is the standard 103.
I never got round to a 103R.
It does sound kind of crazy - but cross a 17D3 with a 103 and you kinda end up with a 10X5.
Anyways, when all is said and done, given your stated preferences, I would defo look at a Zu 103.
