Rob-I have no idea what "highly touted SS phono stages" you are talking about, but one thing I do know is that they can't be that good in terms of S/N ratio if they have as much noise as a tube phono stage. I have been around tubes my entire life and I know that you can't send a microvolt signal to a tube and expect to hear an output signal with no noise. I used to buy AAA graded tubes from Mike Elliott which he said required rejecting 100 tubes in order to find one tube that would meet his AAA noise requirements. And quiet today doesn't mean quiet tomorrow.
the best pure tube 'stages i've tried reach a precipice at ~45-50 db of gain before they get too noisy. SS stages like the klyne, Krell, Pass, Whest and sutherland I've owned were capable of 65+ db of gain but also suffered from significant noise at that level. The work around that did it for me was lowering the gain to around 50 db and making it up with a high gain line stage (20+ db). I've found this pretty much evened the playing field between tubes and SS (noise-wise). there are many moving pieces of course i.e. your cart's output voltage, amps input sensitivity, speaker sensitivity etc.
