I've had exactly your analogue setup and upgraded to Michell Gyro SE. I kept RB300 and later-on modded with Incognito kit and Clearaudio heavy counterweight. There were a few cartridges and Lyra Helikon is current. Before I've acquired Benz M.09 for half of price and was also very pleased. Now I have Benz M.09 as a backup or I might sell it as well if things won't go well.
So my setup is now(new prices)
Michell Gyro Se -- $1200(no arm)
RB300 Incognito mods + Clearaudio heavy counterweight --$350
Lyra Helikon(acquired from overseas) -- $1200
Walker Audio disks only(as a part from valid points) -- $60
This setup literally drives me so crazy that whenever I try to listen to my digital setup, I get fatigue an few minutes and switch back to vinyl. Besides above list I would certainly suggest a dedicated phono preamp instead of built-in. In my case I have ARC PH3 that I call "Botomless beauty" in the sence of that there is no limit to its bottom.
If you will deside to stay with your Classe preamp, you should go for higher output cartridges such as Dynavector 20XH, Benz Glider H2... Sumiko BPS is great but there is no 3D imaging from that cartridge due to the limit in bottom-end resolution. From the simple principals of electrical engineering I can tall that the larger coil has larger inductance and so larger voltage is being dropped on the bottom freequencies. So the lower output carts have much better 3D and bass.
