Ideas on how to improve setup please

Hi guys -- it's been awhile since I last checked in here as I've been using the same setup for a few years now and was wondering what suggestions I could get for improving the overall sound quality on my system. I think my best options may be to get the Blue Ortofon and KT88s - but wanted to see if there are any more thoughts on this or my wires and/or anything else. All components of my setup listed below:

Totem Staaf speakers
PrimaLuna ProLogue Classic Integrated (w/EL34s)
Bluesound Node 2
Pro-Ject Carbon Espirit  (with Red Ortofon)
Cambridge Audio Azur 651P Moving Magnet MM Moving Coil MC Phono Preamp
Affinity™ Premium 12AWG Hi-Fi Speaker Cable with Solid Brass Interchangeable Terminals
Premium 2 RCA Plug/2 RCA Plug M/M 22AWG Cable

Any questions/clarifications please let me know -- thanks very much for your time!

Matt
