Hi Kenl
Jeff Rowland CADENCE was not a top rated phono stage. The DACT was much better then, and better still was the Klyne.
Today, I use custom tube pre-pre (TFK CCa) without coupling cap to the input signal or any kind of feedback & a clever anti-active RIIA MM phonostage (TFK ECC803s/Raytheon 6J5 St) that supply 250mV-3V adjustable with a passive attenuator directly to the power amp.
I would not advise anyone to go that route as it has too many issues to deal with. (In fact I would not recommend a tube phonostage or likely an active preamp).
Instead, I can confidently recommend the small EINSTEIN as the real champion of the most.
But if you really want to go further, please arrange a listening audition for the VDH "THE GRAIL". In my research I've found it as a real treasure way beyond the Lamm, Jadis, Manley, Goldmund, Klyne, TEAD, FM 222, and some lower level others that I can't remember.
Be very demanding! There are not many phonostages out there that can make the difference. Do not overpay for something that is just works. Search for the exciting factor!
