Ok...the VPI Scout Prime with an Ortofon Bronze (I am assuming 2M series since the Rega is only MM loading) is your strongest component. I am wondering though, if you are limiting it by using the integrated phonostage of the Rega Brio. I'm not a big fan of integrated anything, but especially not for the phonostage. I'd maybe consider borrowing a proper separate phono pre-amp from your dealer. A good all-rounder is the Sutherland Insight. Music Direct sells them and gives you a generous 60-day return period should you not be happy with it.
Speakers are so subjective; not only is their sound a consideration, but their style also should influence your decision. What looks good to me might not you and might not fit the rest of your decor. I'm a fan of Martin Logan electrostatic paneled speakers. They are not the most efficient and will get better the more power you throw at them. They are very fast and accurate and provide a nice sound stage, but they have compromises. Biggest one being there is a very narrow sweet spot for the listener. The only cone speakers I would consider ditching the Logans for are Tidal or Aerial Acoustics (that I have heard). But those are super expensive!!! Looking at the speaker selection offered at say, Music Direct, I think Sonus Faber has one of the better reputations. I've not heard them, but know the company is well respected. Focal also, but the ones sold at MD are their lowest end (I think). I'd look at Stereophile online and see what speakers they recommend in your price range.
