Best Phono You've Heard Under $2200

Just a little over your budget new - Manley Chinook.

The Nova is quite good, super quiet and hyper linear. The mentioned Manley and Gold Note are great. The Gold Note makes loading and EQ changes dope simple. Stretch and find a Herron IF you can.Also IF you don't need a ton of gain, a Croft RIAA is a fantastic tube unit from the UK. A sleeper SS unit is the Chord....also easy top/front panel changes...

I have an SPL Phonos that I like but I'm interested in the ones mentioned above.I wonder how much better it can get going into my Octave V70 Class A?

Lindemann Limetree Phono.

There are several units-tube/SS listed  in your price range. Even if a unit is a couple bucks more, you can always negotiate.  Pick a few models and research 

A new $5K unit 3+ years old, now used is only worth HALF

Goldnote, Parasound, Rogue, Aurorasound, Manley,Cyrus Icon Audio... plenty of choices
