Going from your machine with the Virtuoso to a $1000 machine with the same grinder, will get you hardly better shots, sorry. The virtuoso, whether preciso burrs or not, is going to hold you back big time. I doubt it is even giving you the full potential of the humble Saeco. I would HIGHLY recommend you lower your machine upgrade budget to about $600 and look for something used like a PID Silvia or a small HX like Nuova Simonelli Oscar, Pasquini Livia 90, or if you can find one in good shape, I've been happy with my Pasquini Livietta/Olympia Maximatic/Coffex for a couple years. Put that other $400 toward a new grinder. Stepping up to $400 on your grinder will probably be the biggest improvement for you right now. That will get you either a Baratza Vario or a used Mazzer Super Jolly, which are both excellent grinders. I prefer my Super Jolly for robustness, but Vario supposedly produces just as good of coffee. If you have $1000 to spend, you should NOT be hanging on to that Virtuoso whilst thinking a $1000 machine is going to make a difference! I'm not trying to be condescending, it's just the truth.
