Tubeyist sounding Pre-amp?

You’ve got an amp with warm and liquid sonics that mates well with tube preamps. Have you tried rolling in NOS tubes in the SF? Mullards are the way to go, but are expensive.

A preamp with 6SN7 tubes will present a classic tube sound, with NOS of course.

In the Cary line...
Probably Cary 98.

not the 05

ebm
CJ preamp jump on one now!!!!!!

Agree the older CJ preamps were beautiful sounding like honey or maple syrup!   Also try the old Counterpoint preamps!

in the Cary line the spl94 was better imo then the 98 the 94 had tube rectification the 98 had moved on to SS. I had a 94 slightly moded one  with AudionNote caps and it was very musical and warm. I liked it better then the 98 but hard to find one now.

Most preamps that use multiple 6sn7 tubes are a good example . 
Don't sax makes a exceptionally hoof preamp for under $3k spend the upgrade 
With better output caps .
