There's a pair of Joseph Audio RM25XLs for sale here a bit below your price target. I know you mentioned the SF Venere above, and having had them both in my system (Venere 2.5) I'd put the RM25XLs at a significantly higher level in terms of refinement, imaging/soundstage, linearity, and overall build quality. They also go a bit lower than the 2.5s and are likely an easier load for your amp as they don't dip below 6 Ohms. Just another option and best of luck.
