Favorite Preamps without phono section

Backert is another to consider. Just over 4 years ago I bought their Rhumba line stage and it took my system to another level. After a couple of years, curiosity got the better of me and I auditioned the Rhumba Extreme which provided additional  improvements across the board. They have a generous trade up policy and the people are great to deal with. Here's a fairly recent review:

If it demonstrates anything at all, at every opportunity to sing the praises of Aric at Aric Audio, I will happily do so. His gear is world class as well as his customer service! I worked with Aric on a bespoke preamplifier some years ago that we named The Motherlode. Every piece of gear since taking delivery has come and gone, but The Motherlode has never left the rack. Do yourself a favor and reach out  to him to discuss your specific needs. 

I have a few in rotation however an old favourite of mine ARC REF 40.
