plz suggest a tube preamp to match Parasound A21 amp


Hi, I'd like to add some tube attitude to the signal entering my Parasound A21 amp. Plz suggest decent tube preamp under $2,500...New or used, but no 20-30 years old, vintage stuff plz. Fully balanced design is preferred. Combined XLR / RCA inputs/outputs are necessary. Recently tried Schiit Freya Plus, but didn't like it due to weird volume control function and delayed start. Tnx.

Freya +/A21 combo sound better than my SS (p6)  and I know that I could play with tube rolling to polish the SQ, but that clicking-scraping volume control and pretty long start delay of Freya is Just not for me. 
If Balanced input of A21 used the impedance is 66 kΩ..... 33kΩ is for RCA input only.
