LCR phono stage with cascode input - any obvious improvements?

You shouldn't assume i didn't use ferrite beads though...i actually used some of the most expensive components on the market in all my projectss in the last decade .I still have those 4 Siemens e810f and 1 Mullard almost brand new(as i only used them for a month doing tests and i couldn't find a single decent use for audio since 2013...and i cloned that Luxman cl34 as well...High gm tubes for phono use are better than what you need with normal pasive or active riaa, while eating 8...20 time more current for the same task and equal perceived beneffits as an ecc83 circuit and not good enough for direct loading with an lcr netrwork nor as good as it needs for best signal to noise compared to silicon realm...It's just overkill for mm and poor design for mc...
