You have a nice system.
It's hard to point a finger at a weak area within the context of what you have. Your arm and cartridge match the turntable well. The phono stage and amp, I'm sure work together nicely. You suggest speakers, but Curas were very good and you may have your work cut out to improve on them at a sensible price.
One thing. Whilst the mid and top end should be excellent, Curas were never the most impactful in bass. Have you considered a compact sub-woofer? It could be beneficial.
Also, are your interconnects and speaker cables decent quality? They can make a huge difference. Poor cabling sucks the life out of the sound.
It is impossible for anything digital to sound analogue, because it isn't analogue!
