Phonostage

Need help. Purchased a cartridge,benz micro LPS, currently have a nova phonomena phonostage which I believe is my weak link. Would like to upgrade phonostage with tube or solid state with at least 62 db of gain. After a natural sound with lots of detail. Listen mostly to jazz to include female singers would like to have as much depth as possible. Budget is $5000 new or used. Suggestions please.
