Tube preamp match with Solid Stare amp

Would this work for you?

Output impedance = 250 Ohms from 2Hz to 400KHz

Line stage input impedance = 100 Kohm Ω single-ended / 200 Kohm Ω balanced

You can get with/without phono stage

Aric Audio Motherlode XL preamp.  Off the hook good...

I might add a used Cary SLP 05.  Cary offers upgrade is not current model.  I use one with AGD Audions and really like the combination.  

A used Audio Research Reference 6 should fit your needs.

All the best.
