I agree, I tested the Topping Pre90 with my Tube DAC and it gives lots of distortion in tweeter and **not recommended if you are running an Tube Dacs**. YOu can try on integrated DACS or R2R works fine on them.
Finally I changed to Gustard P26 preamp and it works fine as it has 47K Ohms input impedance.
